interoperabilidad

Sign up for SEMIC 2023 and discover the interoperable Europe in the era of artificial intelligence. According to the forecasts of the European Commission, by 2025, the global volume of data will have increased by 530%, and in this context, it is crucial to ensure data interoperability and reuse. Thus, the European Union is working on creating a digital model that promotes data sharing while ensuring people's privacy and data interoperability.

The European Data Strategy includes the launch of common and interoperable data spaces in strategic sectors. In this context, various initiatives have emerged to discuss the processes, standards, and tools suitable for data management and exchange, which also serve to promote a culture of information and reuse. One of these initiatives is SEMIC, the most important interoperability conference in Europe, whose 2023 edition will take place on October 18th in Madrid, organized by the European Commission in collaboration with the Spanish Presidency of the Council of the European Union.

SEMIC 2023, which can also be attended virtually, focuses on 'Interoperable Europe in the AI era.' The sessions will address data spaces, digital governance, data quality assurance, generative artificial intelligence, and code as law, among other aspects. Information about the proposal for an Interoperable Europe Law will also be presented.

Pre-Workshops

Attendees will have the opportunity to learn about specific use cases where public sector interoperability and artificial intelligence have mutually benefited. Although SEMIC 2023 will take place on October 18th, the day before, three interesting workshops will also be held, which can be attended both in-person and virtually:

• Artificial Intelligence in Policy Design for the Digital Age and in Legal Text Writing: This workshop will explore how AI-driven tools can assist policymakers in public policy formulation. Different tools, such as the Policy Analysis Prototype (SeTA) or intelligent functionalities for legal drafting (LEOS), will be discussed.
• Large Language Models in Support of Interoperability: This session will explore the methods and approaches proposed for using large language models and AI technology in the context of semantic interoperability. It will focus on the state of LLM and its application to semantic clustering, data discovery, and terminology expansion, among other applications supporting semantic interoperability.
• European Register of Public Sector Semantic Models: This workshop will define actions to create an entry point for connecting national collections of semantic assets.

Interactions Between Artificial Intelligence, Interoperability, and Semantics

The main SEMIC 2023 conference program includes roundtable discussions and various working sessions that will run in parallel. The first session will address Estonia's experience as one of the first European countries to implement AI in the public sector and its pioneering role in interoperability.

In the morning, an interesting roundtable will be held on the potential of artificial intelligence to support interoperability. Speakers from different EU Member States will present success stories and challenges related to deploying AI in the public sector.

In the second half of the morning, three parallel sessions will take place:

• Crafting Policies for the Digital Age and Code as Law: This session will identify the main challenges and opportunities in the field of AI and interoperability, focusing on 'code as law' as a paradigm. Special attention will be given to semantic annotation in legislation.
• Interconnecting Data Spaces: This session will address the main challenges and opportunities in the development of data spaces, with a special focus on interoperability solutions. It will also discuss synergies between the Data Spaces Support Center (DSSC) and the European Commission's DIGIT specifications and tools.
• Automated Public Services: This session will provide an approach to automating access to public services with the help of AI and chatbots.

In the afternoon, three more parallel sessions will be held:

• Knowledge Graphs, Semantics, and AI: This session will demonstrate how traditional semantics benefit from AI.
• Data Quality in Generative and General-Purpose AI: This session will review the main data quality issues in the EU and discuss strategies to overcome them.
• Trustworthy AI for Public Sector Interoperability: This session will discuss the opportunities for using AI for interoperability in the public sector and the transparency and reliability challenges of AI systems.

In the afternoon, there will also be a roundtable discussion on the upcoming challenges, addressing the technological, social, and political implications of advances in AI and interoperability from the perspective of policy actions. Following this panel, the closing sessions will take place.

The previous edition, held in Brussels, brought together over 1,000 professionals from 60 countries, both in-person and virtually. Therefore, SEMIC 2023 presents an excellent opportunity to learn about the latest trends in interoperability in the era of artificial intelligence.

On September 11^th, a webinar was held to review Gaia-X, from its foundations, embodied by its architecture and trust model called Trust Framework, to the Federation Services that aim to facilitate and speed up access to the infrastructure, to the catalogue of services that some users (providers) will be able to make available to others (consumers).

The webinar, led by the manager of the Spanish Gaia-X Hub, was led by two experts from the Data Office, who guided the audience through their presentations towards a better understanding of the Gaia-X initiative. At the end of the session, there was a dynamic question and answer session to go into more detail. A recording of this seminar can be accessed from the Hub's official website,[Forging the Future of Federated Data Spaces in Europe | Gaia-X (gaiax.es)]

Gaia-X as a key building block for forging European Data Spaces

Gaia-X emerges as an innovative paradigm to facilitate the integration of IT resources. Based on Web 3.0 technology models, the identification and traceability of different data resources is enabled, from data sets, algorithms, different semantic or other conceptual models, to even underlying technology infrastructure (cloud resources). This serves to make the origin and functioning of these entities visible, thus facilitating transparency and compliance with European regulations and values.

The INSPIRE (Infrastructure for Spatial Information in Europe) Directive sets out the general rules for the establishment of an Infrastructure for Spatial Information in the European Community based on the Infrastructures of the Member States. Adopted by the European Parliament and the Council on 14 March 2007 (Directive 2007/2/EC), it entered into force on 25 April 2007.

INSPIRE makes it easier to find, share and use spatial data from different countries. The information is available through an online portal where it can be found broken down into different formats and topics of interest.

To ensure that these data are compatible and interoperable in a Community and cross-border context, the Directive requires the adoption of common Implementing Rules specific to the following areas:

• Metadata
• Data sets
• Network services
• Data sharing and services
• Spatial data services
• Monitoring and reporting

The technical implementation of these standards is done through Technical Guidelines, technical documents based on international standards and norms.

Inspire and semantic interoperability

These rules are considered Commission decisions or regulations and are therefore binding in each EU country. The transposition of this Directive into Spanish law is developed through Law 14/2010 of 5 July, which refers to the infrastructures and geographic information services of Spain (LISIGE) and the IDEE portal, both of which are the result of the implementation of the INSPIRE Directive in Spain.

Semantic interoperability plays a decisive role in INSPIRE. Thanks to this, there is a common language in spatial data, as the integration of knowledge is only possible when a homogenisation or common understanding of the concepts that constitute a domain or area of knowledge is achieved. Thus, in INSPIRE, semantic interoperability is responsible for ensuring that the content of the information exchanged is understood in the same way by any system.

Therefore, in the implementation of spatial data models in INSPIRE, in GML exchange format, we can find codelists that are an important part of the INSPIRE data specifications and contribute substantially to interoperability.

In general, a codelist (or code list) contains several terms whose definitions are universally accepted and understood. Code lists promote data interoperability and constitute a shared vocabulary for a community. They can even be multilingual.

INSPIRE code lists are commonly managed and maintained in the central Federated INSPIRE Registry (ROR) which provides search capabilities, so that both end-users and client applications can easily access code list values for reference.

Registers are necessary because:

• They provide the codes defined in the Technical Guidelines, Regulations and Technical Specifications necessary to implement the Directive.
• They allow unambiguous references of the elements.
• Provides unique and persistent identifiers for resources.
• Enable consistent management and version control of different elements

The code lists used in INSPIRE are maintained at:

• The Inspire Central Federated Registry (ROR).
• The register of code lists of a member state,
• The list registry of a recognised external third party that maintains a domain-specific code list.

To add a new code list, you will need to set up your own registry or work with the administration of one of the existing registries to publish your code list. This can be quite a complicated process, but a new tool helps us in this task.

Re3gistry is a reusable open-source solution, released under EUPL, that allows companies and organisations to manage and share \"reference codes\" through persistent URIs, ensuring that concepts are unambiguously referenced in any domain and facilitating the management of these resources graphically throughout their lifecycle.

Funded by ELISE, ISA2 is a solution recognised by the Europeans in the Interoperability Framework as a supporting tool.

Illustration 3: Image of the Re3gister interface

Re3gistry is available for both Windows and Linux and offers an easy-to-use Web Interface for adding, editing, and managing records and reference codes. In addition, it allows the management of the complete lifecycle of reference codes (based on ISO 19135: 2005 Integrated procedures for the registration of reference codes)

The editing interface also provides a flag to allow the system to expose the reference code in the format that allows its integration with RoR, so that it can eventually be imported into the INSPIRE registry federation. For this integration, Reg3gistry makes an export in a format based on the following specifications:

• The W3C Data Catalogue (DCAT) vocabulary used to model the entity registry (dcat:Catalog).
• The W3C Simple Knowledge Organisation System (SKOS) which is used to model the entity registry (skos:ConceptScheme) and the element (skos:Concept).

Other notable features of Re3gistry

• Highly flexible and customisable data models
• Multi-language content support
• Support for version control
• RESTful API with content negotiation (including OpenAPI 3 descriptor)
• Free-text search
• Supported formats: HTML, ISO 19135 XML, JSON
• Service formats can be easily added or customised (default formats): JSON and ISO 19135 XML
• Multiple authentication options
• Externally governed elements referenced through URIs
• INSPIRE record federation format support (option to automatically create RoR format)
• Easy data export and re-indexing (SOLR)
• Guides for users, administrators, and developers
• RSS feed

Ultimately, Re3gistry provides a central access point where reference code labels and descriptions are easily accessible to both humans and machines, while fostering semantic interoperability between organisations by enabling:

• Avoid common mistakes such as misspellings, entering synonyms or filling in online forms.
• Facilitate the internationalisation of user interfaces by providing multilingual labels.
• Ensure semantic interoperability in the exchange of data between systems and applications.
• Tracking changes over time through a well-documented version control system.
• Increase the value of reference codes if they are widely reused and referenced.

More about Re3gistry:

As more of our daily lives take place online, and as the importance and value of personal data increases in our society, standards protecting the universal and fundamental right to privacy, security and privacy - backed by frameworks such as the Universal Declaration of Human Rights or the European Declaration on Digital Rights - become increasingly important.

Today, we are also facing a number of new challenges in relation to our privacy and personal data. According to the latest Lloyd's Register Foundation report, at least three out of four internet users are concerned that their personal information could be stolen or otherwise used without their permission. It is therefore becoming increasingly urgent to ensure that people are in a position to know and control their personal data at all times.

Today, the balance is clearly tilted towards the large platforms that have the resources to collect, trade and make decisions based on our personal data - while individuals can only aspire to gain some control over what happens to their data, usually with a great deal of effort. 

This is why initiatives such as MyData Global, a non-profit organisation that has been promoting a human-centred approach to personal data management for several years now and advocating for securing the right of individuals to actively participate in the data economy, are emerging. The aim is to redress the balance and move towards a people-centred view of data to build a more just, sustainable and prosperous digital society, the pillars of which would be:

• Establish relationships of trust and security between individuals and organisations.
• Achieve data empowerment, not only through legal protection, but also through measures to share and distribute the power of data.
• Maximising the collective benefits of personal data, sharing it equitably between organisations, individuals and society.

And in order to bring about the changes necessary to bring about this new, more humane approach to personal data, the following principles have been developed:

1 - People-centred control of data.

It is individuals who must have the power of decision in the management of everything that concerns their personal lives. They must have the practical means to understand and effectively control who has access to their data and how it is used and shared.

Privacy, security and minimal use of data should be standard practice in the design of applications, and the conditions of use of personal data should be fairly negotiated between individuals and organisations.

2 - People as the focal point of integration

The value of personal data grows exponentially with its diversity, while the potential threat to privacy grows at the same time. This apparent contradiction could be resolved if we place people at the centre of any data exchange, always focusing on their own needs above all other motivations.

Any use of personal data must revolve around the individual through deep personalisation of tools and services.

3 - Individual autonomy

In a data-driven society, individuals should not be seen solely as customers or users of services and applications. They should be seen as free and autonomous agents, able to set and pursue their own goals. 

Individuals should be able to securely manage their personal data in the way they choose, with the necessary tools, skills and support.

4 - Portability, access and re-use

Enabling individuals to obtain and reuse their personal data for their own purposes and in different services is the key to moving from silos of isolated data to data as reusable resources. 

Data portability should not merely be a legal right, but should be combined with practical means for individuals to effectively move data to other services or on their personal devices in a secure and simple way.

5 - Transparency and accountability

Organisations using an individual's data must be transparent about how they use it and for what purpose. At the same time, they must be accountable for their handling of that data, including any security incidents.

User-friendly and secure channels must be created so that individuals can know and control what happens to their data at all times, and thus also be able to challenge decisions based solely on algorithms.

6 - Interoperability

There is a need to minimise friction in the flow of data from the originating sources to the services that use it. This requires incorporating the positive effects of open and interoperable ecosystems, including protocols, applications and infrastructure. This will be achieved through the implementation of common norms and practices and technical standards.

The MyData community has been applying these principles for years in its work to spread a more human-centred vision of data management, processing and use, as it is currently doing for example through its role in the Data Spaces Support Centre, a reference project that is set to define the future responsible use and governance of data in the European Union.

And for those who want to delve deeper into people-centric data use, we will soon have a new edition of the MyData Conference, which this year will focus on showcasing case studies where the collection, processing and analysis of personal data primarily serves the needs and experiences of human beings.

On 20 October, Madrid will host a new edition of the Data Management Summit Spain. This event is part of the Data Management Summit (DMS) 2022, which was previously held in Italy (7 July) and Latam (20 September).

The event is aimed at a technical audience: CiOs, CTOs, CDOs, CIOs, CIOs, Business Intelligence Officers and Data Scientists in charge of implementing emerging technologies in order to solve new technological challenges and align with new business opportunities.

Date and time

The conference will take place at the Nebrija University, on 20 October 2022, from 9:30 to 19:30.

The day before, a DMS prologue will take place in the same space, exclusively for representatives of public administrations, from 14:00 to 19:30.

Agenda

The agenda is made up of presentations, round tables and group dynamics between professionals, which will allow networking.

The prologue on the 19th will focus on open data and the exchange of information between administrations. Carlos Alonso, Director of the Data Office Division, will be one of the speakers. Among the different activities, there are two group dynamics that will focus on open data and interoperability, as well as two round tables, in the first of which the red.es coordinator of the datos.gob.es platform will participate:

• Round table 1: Open Data and data interoperability in public administrations.
• Round table 2: Challenges and barriers to data exchange in the public sector.

Day 20 will have a business-oriented focus.  This second day will also feature expert presentations and group dynamics focusing on data governance, data quality, master data and data architecture, among other topics. There will be three round tables:

• Roundtable 1: “Data Architecture, Data Mesh or Data Fabric?” which will discuss the Data Mesh architecture pattern, with a decentralised approach, as opposed to Data Fabric, which promotes a single unified data architecture.
• Roundtable 2: “How Data Governance changes with the new paradigm of open banking” that will address the evolution towards an economy based on full interoperability and APIs, where the traceability of processes is complete.
• Roundtable 3: “How to converge the different data quality models”, focusing on how to measure data quality, how to manage quality processes automatically and how to avoid Data Lake corruption.

You can see more about the event in this video.

More information on the summit website.

Nowadays we can find a great deal of legislative information on the web. Countries, regions and municipalities make their regulatory and legal texts public through various spaces and official bulletins. The use of this information can be of great use in driving improvements in the sector: from facilitating the location of legal information to the development of chatbots capable of resolving citizens' legal queries.

However, locating, accessing and reusing these documents is often complex, due to differences in legal systems, languages and the different technical systems used to store and manage the data.

To address this challenge, the European Union has a standard for identifying and describing legislation called the European Legislation Identifier (ELI).

What is the European Legislation Identifier?

The ELI emerged in 2012 through Council Conclusions (2012/C 325/02) in which the European Union invited Member States to adopt a standard for the identification and description of legal documents. This initiative has been further developed and enriched by new conclusions published in 2017 (2017/C 441/05) and 2019 (2019/C 360/01).

The ELI, which is based on a voluntary agreement between EU countries, aims to facilitate access, sharing and interconnection of legal information published in national, European and global systems. This facilitates their availability as open datasets, fostering their re-use.

Specifically, the ELI allows:

• Identify legislative documents, such as regulations or legal resources, uniquely by means of a unique identifier (URI), understandable by both humans and machines.
• Define the characteristics of each document through automatically processable metadata. To this end, it uses vocabularies defined by means of ontologies agreed and recommended for each field.

Thanks to this, a series of advantages are achieved:

• It provides higher quality and reliability.
• It increases efficiency in information flows, reducing time and saving costs.
• It optimises and speeds up access to legislation from different legal systems by providing information in a uniform manner.
• It improves the interoperability of legal systems, facilitating cooperation between countries.
• Facilitates the re-use of legal data as a basis for new value-added services and products that improve the efficiency of the sector.
• It boosts transparency and accountability of Member States.

Implementation of the ELI in Spain

The ELI is a flexible system that must be adapted to the peculiarities of each territory. In the case of the Spanish legal system, there are various legal and technical aspects that condition its implementation.

One of the main conditioning factors is the plurality of issuers, with regulations at national, regional and local level, each of which has its own means of official publication. In addition, each body publishes documents in the formats it considers appropriate (pdf, html, xml, etc.) and with different metadata. To this must be added linguistic plurality, whereby each bulletin is published in the official languages concerned.

It was therefore agreed that the implementation of the ELI would be carried out in a coordinated manner by all administrations, within the framework of the Sectoral Commission for e-Government (CSAE), in two phases:

• Due to the complexity of local regulations, in the first phase, it was decided to address only the technical specification applicable to the State and the Autonomous Communities, by agreement of the CSAE of 13 March 2018.
• In February 2022, a new version was drafted to include local regulations in its application.

With this new specification, the common guidelines for the implementation of the ELI in the Spanish context are established, but respecting the particularities of each body. In other words, it only includes the minimum elements necessary to guarantee the interoperability of the legal information published at all levels of administration, but each body is still allowed to maintain its own official journals, databases, internal processes, etc.

With regard to the temporal scope, bodies have to apply these specifications in the following way:

• State regulations: apply to those published from 29/12/1978, as well as those published before if they have a consolidated version.
• Autonomous Community legislation: applies to legislation published on or after 29/12/1978.
• Local regulations: each entity may apply its own criteria.

How to implement the ELI?

The website https://www.elidata.es/ offers technical resources for the application of the identifier. It explains the contextual model and provides different templates to facilitate its implementation:

• URI template for state and regional regulations.
• URI template for the official journal.

It also offers the list of common minimum metadata, among other resources.

In addition, to facilitate national coordination and the sharing of experiences, information on the implementation carried out by the different administrations can also be found on the website.

The ELI is already applied, for example, in the Official State Gazette (BOE). From its website it is possible to access all the regulations in the BOE identified with ELI, distinguishing between state and autonomous community regulations. If we take as a reference a regulation such as Royal Decree-Law 24/2021, which transposed several European directives (including the one on open data and reuse of public sector information), we can see that it includes an ELI permalink.

In short, we are faced with a very useful common mechanism to facilitate the interoperability of legal information, which can promote its reuse not only at a national level, but also at a European level, favouring the creation of the European Union's area of freedom, security and justice.

In the current context, digitalisation has expanded exponentially, reaching beyond the boundaries of the private sector and consolidating itself as one of the great challenges in all productive sectors of society. This process has brought with it the massive generation of data from which to extract value. However, according to an IDC/EMC study, it is believed that, despite the fact that the volume of data will multiply exponentially in the short term, only 1% of the data generated is used, processed and exploited. One of the reasons for this lies in the inconsistency and inflexibility of data models, which block data integration.

In this regard, the Spanish government's Recovery, Transformation and Resilience Plan, which details Spain's strategy for channelling EU funds to repair the damage caused by the pandemic, emphasises technological reforms and investments focused on building a more sustainable future. One of the main challenges in this area is to boost data sharing, mainly in those sectors with the greatest impact on society, such as health and tourism.

To this end, smart data models play a fundamental role. But what exactly are they?

visión común que proporciona una base técnica para lograr la apertura de la innovación.

What are Smart Data Models?

A traditional data model is a representation of the elements of a dataset and their relationships and connections to each other. Smart Data Models go one step further. They are common and compatible data models, with the objective of supporting a digital marketplace of interoperable and replicable smart solutions across multiple sectors, so that the availability of data in specific domains is homogenised.

These models propose a common vision that provides a technical basis for unlocking innovation.

SDM Initiative

The FIWARE Foundation, TM Forum, IUDX and OASC have joined forces to lead a joint collaborative initiative to bring together intelligent data models by domains, making them available to organisations and any user who wants them. This is known as the SDM (Smart data models) initiative, in which all data models are public.

In this way, it responds to the new data modelling needs at the speed required by the market, reusing models that have already been tested in real scenarios.

How does it work?

The fundamental objective of SDM is that organisations can evolve their vision of data exchange towards a sharing that supports both the so-called Data Economy and the data spaces.

The Data Economy is nothing more than the set of activities and initiatives whose business model is based on the discovery and exploitation of data to identify opportunities that generate products and services.

SDM classifies information by domains or industrial sectors, creating a repository for each of them. In addition, each domain contains sub-modules with the relevant topics for that domain and, within each topic, the related data models. However, shared cross-cutting elements are also available for all domains. For each of these repositories, models can be extracted free of charge. It is also possible to contribute to the initiative by filling in a collaboration form to create new ones.

To facilitate sharing and common understanding, each model includes three elements:

• The model's technical representation that defines the data and its relationships, using JSON structures.
• The specification or manual with the functional descriptions of each of the elements contained in the model.
• Examples to ensure understanding.

In addition to its public nature and free use, it has a licence that allows users to make modifications if they consider it necessary, as well as to share these modifications with the rest of the users. To this end, a workflow is defined according to the phases of the life cycle of the data models, which presents three stages:

• Official: the data models have already been accepted and are fully available to users with the three elements described above.
• In harmonisation: the models have already been accepted, but are still in progress to complete the elements.
• In incubation: the models are being developed and supported by the organisation to achieve an official model.

Through this initiative, data models sharing at all levels will be made more dynamic. For the moment, models have already been homogenised in the domains of smart cities, the agri-food sector, water treatment, energy, environment, sensor technology, robotics, aeronautics, tourist destinations, health and manufacturing industry, as well as some transversal ones such as social media or incident monitoring, although not all to the same extent, as shown in the following image with the number of models included in each domain.

It is, without a doubt, an initiative that facilitates the path towards the data-driven transformation of products and services, providing the opening of models as the technical basis on which the adoption of reference architectures will be based. If you want to go deeper, the SDM itself contains a "Learning zone" section to facilitate learning about the initiative and encourage its use, including self-explanatory videos.

There is also a whole series of tools for those users who, although experts in their sector of activity, are not experts in the generation of data models. Under the tools menu item, there are services that allow users to generate a draft data model with an example, an assisted online data model editor, options to generate examples from existing data models, and options to incorporate the @context element that allows connection to linked data solutions.

Global initiatives such as SDM are of great importance when it comes to agreeing benchmarks to optimise citizen services. They constitute a further step in the objective of achieving common data spaces, making available contrasted data models. This milestone is a major accelerator for its transcendence, even at European level, with major initiatives already underway, such as GAIA-X.

In any project related to data, it is common to have different sources of information. Data is key for companies and public administrations, in decision making or as a basis for the implementation of projects, services or products. But if these data sources display information in a heterogeneous way, it is difficult to operate.

In the world of open data, each administration covers a different scope, be it territorial - municipal, provincial, regional or national - or jurisdictional - for example, each ministry deals with data from a specific area: ecological transition, health, mobility, etc. -. To be able to carry out projects that cover several areas, we will need interoperable data. Otherwise, the exchange and integration of data within and between organisations will be incompatible.

Why is data harmonisation important?

Today, public administrations manage large amounts of data in different formats, with different management methods. It is common to host multiple copies in many different repositories. These data are often disseminated in portals across Europe without any harmonisation in terms of content and presentation. This explains the low level of re-use of existing information on citizens and businesses. Harmonisation of information allows for consistent and coherent data in a way that is compatible and comparable, unifying formats, definitions and structures.

This shaping of data can be done individually for each project, but it entails a high cost in terms of time and resources. It is therefore necessary to promote standards that allow us to have already harmonised data. Below are several examples of initiatives that advocate the search for common requirements, which are included in this visual:

Ministry of Transport, Mobility and Urban Agenda

The Ministry of Transport, Mobility and Urban Agenda is working on a National Access Point (PAN, in its Spanish singles) where unified data on different modes of transport is collected. The creation of this portal responds to compliance with Commission Delegated Regulation (EU) 2017/1926, which establishes the obligation for authorities, operators, managers and providers of transport services to provide information on multimodal journeys in the EU, based on a series of specifications that ensure its availability and reliability. Among other issues, it indicates that the content and structure of the relevant travel and traffic data need to be adequately described using appropriate metadata.

The creation of this Single Access Point was published in the Official State Gazette (BOE) on 22 February. The text indicates that the minimum universal traffic information related to road safety will be made public, whenever possible and free of charge, with a special focus on real-time services.

At the moment, the PAN has data from the DGT, the Basque Government, the Generalitat de Catalunya, the Madrid City Council and the company Tomtom.

Spanish Federation of Municipalities and Provinces

The Spanish Federation of Municipalities and Provinces (FEMP, in its Spanish singles) has an open data group that has developed two guides to help municipalities implement open data initiatives. One of them is the proposal of 40 datasets that every administration should open to facilitate the reuse of public sector information. This guide not only seeks uniformity in the categories of data published, but also in the way they are published. A fact sheet has been created for each proposed dataset with information on update frequency, formats or recommended display form.

FEMP's future plans include reviewing the datasets published so far to assess whether to add or remove datasets and to include new practical examples.

Also in the field of cities, there is an initiative to further ground the harmonisation of a limited subset of datasets carried out in the framework of the Ciudades Abiertas project, with the collaboration of Red.es. The city councils participating in the project - A Coruña, Madrid, Santiago de Compostela and Zaragoza - have agreed on the opening of 27 harmonised datasets. Currently, common vocabularies have been developed for 16 of them and work continues on the others.

ASEDIE and its Top 3

In 2019, the Multisectoral Information Association (ASEDIE) launched an initiative for all Autonomous Communities to fully open three sets of data: the databases of cooperatives, associations and foundations. It was also proposed that they should all follow unified criteria to facilitate their reuse, such as the incorporation of the NIF of each of the entities.

The results have been very positive. To date, 15 autonomous communities have opened at least two of the three databases. The database of Associations has been opened by all 17 Autonomous Communities.

In 2020, ASEDIE proposed a new Top 3 and started to promote the opening of new databases: commercial establishments, industrial estates and SAT registers. However, due to the fact that not all Autonomous Regions have a register of commercial establishments (because it is not a regional competence), this dataset has been replaced by the Register of Energy Efficiency Certificates.

UniversiData

UniversiData is a collaborative project to promote open data linked to higher education in Spain in a harmonised way. To date, five universities have joined the project: Universidad Autónoma de Madrid, Universidad Complutense de Madrid, Universidad Rey Juan Carlos, Universidad de Valladolid and Universidad Carlos III de Madrid (UC3M).

Within the framework of the project, the "Common Core" specification has been developed, with the aim of providing answers to two questions that the universities ask themselves when opening their data: What datasets should I publish? And how should I do it? That is to say, with which fields, granularity, formats, encodings, frequency, etc. The Common Core coding has been created in accordance with the Law on Transparency, Access to Public Information and Good Governance. Two University Transparency Rankings have also been considered for its development (that of the Fundación Compromiso y Transparencia and that of Dyntra), as well as the document "Towards an Open University: Recommendations for the S.U.E.", of the Conference of Rectors of Spanish Universities (CRUE).

All these initiatives show how data harmonisation can improve the usefulness of data. If we have unified data, its reuse will be easier, as the time and cost of its analysis and management will be reduced.

The Open Data initiative of the Government of Aragon was created by an agreement in 2012 with the aim of creating economic value in the ICT Sector through the reuse of public information, the increase of transparency and the promotion of innovation. All this, in order to boost the development of information society and data interoperability in the Administration. Thanks to this agreement, open data is incorporated into the strategies of the Government of Aragon, who is committed to the effective opening of public data that they hold, understanding as public all data not subject to restrictions of privacy, security or property.

In this context, in 2013, the open data web portal of the Government of Aragon was launched. Since then, Aragón Open Data underwent an exponential growth, driven by the unit responsible for its management, the current General Directorate of Electronic Administration and Information Society, and, of course, by the different data providers: public units, mostly from the Autonomous government. These providers offer their information under open data philosophy from a single access point.

Since the creation of the portal, more services have been developed, such as Aragopedia, Budget or Open Analytics Data. All of them are related to open data reuse and disposition through services that facilitate its use and interpretation. In this line, Aragón Open Data offers diverse applications and training materials, as well as APIs and services that add value to data. Due to these projects, the initiative was selected as the only Spanish experience in the Open Data Leader's Network, held in London in 2016.

The most downloaded resources of the portal include: Cartographic download service e: 1/1000 by municipality, Government of Aragon Contracts, list of municipalities of Aragon or annual holiday calendars of the Autonomous Community and its provinces.

In this wide and diverse framework, in 2016, Aragón Open Data also began a work of identification and integration of the diversity of data generated by the Government of Aragon, in order to facilitate its disposition and opening. The first step was to create an ontology, the Interoperable Information Structure of Aragón EI2A, with the collaboration of the units that possess, create and manage data, participating different areas of the Government of Aragon such as agriculture, finance, culture, geographic information or environment, among others.

The Interoperable Information Structure of Aragón (EI2A) homogenizes structures, vocabularies and characteristics within the framework of Aragón Open Data to mostly resolve the problem of data diversity and heterogeneity in the Administration. A heterogeneity that is a real reflection of the reality and competences of the Administration, but which hinders its opening and reuse.

The EI2A describes the conceptual and logical data model generated by the Government of Aragon, representing entities, properties and relationships. The structure is intended to support data interoperability through its standardization. The Interoperable Information Structure of Aragon aims to relate the content and elements of the different data sets so that data can be standardized and exploited jointly in the Government of Aragon, by combining, simplifying and homogenizing them, regardless of the origin, purpose, model, entities and relationships.

It is in 2017 and 2018 when the EI2A becomes a reality due to Aragón Open Data Pool project. Aragón Open Data Pool is a pilot and innovative project that demonstrates the importance of centralizing and publish data to drive its use and exploitation. Open Data Pool is available since December 2018, based on EI2A.

As a result: more than 140 sources of well-differentiated organisms and purposes, which were previously open in Aragon Open Data (API GA_OD_Core), have been standardized according to the EI2A to be exploited together and offered in a simple way, from a single point of access and with the same query criteria.

This project data are aligned with the semantic web standards for its exploitation, consultation and use (SPARQL endpoint), which is its real potential. This makes data consulting and use possible, regardless of their characteristics and vocabularies. It even allows federating data from portals of different administrations such as Aragón Open Data (under EI2A) and Open Data Euskadi (under ELI).

Another noteworthy aspect is that it is oriented to a non-technical user, by allowing a intuitive and simple navigation using data relationships, putting interoperability into practice through the relation of diverse data using a normal navigation web.

This project has helped to better understand the reality of data incorporated into Aragón Open Data Pool under the EI2A, and confirm the need of data normalization in the production-point, to latter, open and offer them in Aragón Open Data, facilitating their use and reuse, both inside and outside the Administration. But we need a change, sought by data interoperability and reuse guidelines, to open a unique data access point in the Government of Aragon, which today corresponds to a regulatory project. Among its axes of action, this project aim to better identify data, improve its quality at source, and internally support the process from the creation of the data by the different production units, until its publication in Aragón Open Data. In this way, they seek to continue growing, improving and orienting theirselves so that any interested party, institutions, developers or infomediary company can use the information, data and services available for any of their interests, thus contributing to the development of the information society.

With the establishment of the internal market in the European Union, member state administrations need to effectively exchange information beyond their borders in order to be able to comply with public services. Nevertheless, such exchange has posed a challenge since, sometimes, electronically transferring data from one nation to another is not easy. Each national system follows different parameters according to the internal needs of the country that make cross-border administrative procedures into long and costly processes.

However, electronic collaboration among European administrations can speed up and economise such public procedures. In this context, the ISA program of the European Commission started in 2010, which, with an initial budget of 160 million euros, created a joint framework to develop international and interoperable electronic public services for the benefit of citizens and businesses in the EU. This program is based on the interoperability of these services, which not only reduces costs and administrative burdens, but it also contributes to the smooth functioning of the European internal market.

The evolution towards ISA²

ISA² is running from 1 January 2016 until 31 December 2020, replacing the previous ISA programme, supporting both cross-border and intersectoral interaction, as shown in the following video:

With a budget of 131 million euros, distributed over the 5-year duration of the programme, ISA² has a new program designed to achieve the following goals:

• ensure that interoperability activities are well coordinated at EU level;
• develop and operate solutions for the public administrations on the basis of businesses’ and citizens’ needs;
• put in place the necessary instruments to boost interoperability at EU and national level, such as: a revised European Interoperability Framework (EIF); a revised European Interoperability Strategy (EIS); an European Interoperability Reference Architecture (EIRA); and the European Interoperability Cartography (EIC).

This collaborative work  within ISA² resulted in the publication of the version 2.0 of the Core Vocabularies, a set of technical implementation guidelines for the DCAT-AP and the RDF dissemination vocabulary for the EU Budget Vocabulary for representing EU budget data, aimed at increasing government transparency.

Although the program is managed by a specific unit of the European Commission, the DG for Informatics, all member states are actively involved through the ISA² Committee and the ISA² coordination group, which is responsible for ensuring consistency among the program actions.

Achievements regarding semantic interoperability

ISA² is implemented through five work programs, one per year during the period 2016-2020. The member states participating in the 2017 program had to present their proposals last year, providing a solution that is assessed and selected by the ISA² Committee. Once the list of proposed actions is approved, in March 2017, the European Commission will define a work program and allocate a budget for the implementation of the program.

To date, more than 40 actions have been carried out, with special attention to the excellent results obtained by the SEMIC initiative, an action plan to improve semantic interoperability among the different European e-government systems. Within this plan, the ISA² program has developed, along with a group of experts belonging to different institutions of the EU, a set of new data specifications including:

• the DCAT-AP for statistical datasets (StatDCAT), an extension of the DCAT Application Profile to enhance interoperability between descriptions of statistical datasets and open data portals;
• the Core Public Organisation Vocabulary (CPOV), a data model to describe public organisations in the European Union, based on W3C's Organisation Ontology;
• the Core Criterion and Core Evidence Vocabulary (CCCEV), a data model that simplifies the exchange of information between organisations, businesses and citizens in public procurement processes, allowing them to provide the evidence required: CCEV.

In addition, SEMIC continued to provide support on policy matters of different European Commission Directorate-Generals, namely: to DG Employment, Social Affairs and Inclusion through the implementation of a pilot project to link national qualifications systems with ESCO (Skills, Skills, Qualifications and European Occupations); to the Financial Stability, Financial Services and Capital Markets DG (FISMA), to improve the standardization of financial data; or the European Food Safety Agency, to implement an information governance policy.

Through the ISA² program, the SEMIC plan has provided an important push to semantic interoperability in the European Union, in addition to a continuous enrichment thanks to its contributions to the Joinup community, which has more than 1,500 members from different Public Administrations and the European Commission Services. In addition to these initiatives, ISA² has provided the impetus for the development of solutions in many other fields such as open data, electronic invoicing or the geospatial industry. As shown in the web section dedicated to the innovative projects developed within this program.
