Help videos for data reusers in datos.gob.es

Fecha del documento: 09-12-2021

How can I check which datasets are in the catalog?

In a platform such as datos.gob.es, where the frequency of dataset updates is constant, it is necessary to have mechanisms that facilitate massive and automatic queries.

In datos.gob.es we have an API and a SPARQL point to facilitate this task. Both tools allow querying the metadata associated with the datasets of the National Open Data Catalog based on the definitions included in the Technical Interoperability Standard for the Reuse of Information Resources (NTI-RISP).  Specifically, the semantic database of datos.gob.es contains two graphs, one containing the entire Catálogo de datos de datos.gob.es (http://datos.gob.es/catalogo) and another with the URIs corresponding to the taxonomy of primary sectors and the identification of geographic coverage based on the NTI (http://datos.gob.es/nti).

In order to help reusers to perform their searches through these functionalities, we provide users with two videos that show in a simple way the steps to follow to get the most out of both tools.

Video 1: How to make queries to the datos.gob.es catalog through an API?  

An application programming interface or API is a mechanism that allows communication and information exchange between systems. Thanks to the API of datos.gob.es you can automatically query the datasets of a publisher, the datasets that belong to a specific subject or those that are available in a specific format, among many other queries.

The video shows:

  • How to use the datos.gob.es API.
  • What types of queries can be made using this API
  • An example to learn how to list the datasets in the catalog.
  • What other Open Data Initiatives are publishing APIs
  • How to consult other available APIs

You also have at your disposal an infographic with examples of APIs for open data access.

Video 2: How to perform queries to the .gob.es data catalog through the SPARQL point?

A SPARQL point is an alternative way to query the metadata of the datos.gob.es catalog using a service that allows queries over RDF graphs using the SPARQL language.

With this video, you will see:

  • How to use the SPARQL point of datos.gob.es.
  • What queries can be performed using the SPARQL point
  • What methods exist for querying the SPARQL point
  • Examples on how to perform a query to find out which datasets are available in the catalog or how to obtain the list of all the organizations that publish data in the catalog.
  • It also includes examples of SPARQL points in different national initiatives.

These videos are mainly aimed at data reusers. From datos.gob.es we have also prepared a series of videos for publishers explaining the various features available to them on the platform.
