Profile of implementation of DCAT portals for European data

  • Short Name:
    Creator body:
    SEMIC - European Commission
    Within the initiatives on semantic interoperability, the European commission has defined a profile of application of the vocabulary DCAT published by W3C to describe catalogs of data from three key concepts: catalogue, dataset (dataset) and distribution. DCAT-AP has two extensions: GeoDCAT-AP to describe geospatial data sets, series of data sets and services; and StatDCAT-AP to describe statistical data sets.

    Promoter body:
    Political ministry Territorial and Public Function
    Secretariat of state of Public Function
    General Secretariat of Digital Administration

    Within the program ISA2 (Opens in new window) de la Comisión Europea, la iniciativa Comunidad de Interoperabilidad Semántica ( SEMIC (Opens in new window) ) has published a profile of application of the vocabulary of Data catalogues (DCAT) defined by the consortium W3C.

    DCAT-AP comes to solve interoperability of catalogs of data and, in particular, those published by open data portals public administrations in the context of the HAT. Furthermore, the use of this common vocabulary enables also search functionality of data in different catalogues, which provides a clear added value to the sector infomediario.

    The three key concepts that constitute the DCAT-AP are:

    1. Catalogue: as a collection of data sets
    2. Dataset (dataset): as data collection
    3. Pattern: as a specific form of accessing a set of specific data (as a file in a particular format or a API with a specific technology)

    Varios países, incluido España, han extendido el DCAT-AP para responder mejor a sus necesidades específicas.

    StatDCAT-AP (Opens in new window) is an extension of DCAT-AP which provides a vocabulary data for statistical open fully compatible with the repositories of data based on DCAT-AP. In its elaboration, SEMIC has worked with Eurostat (Opens in new window) and CONNECT DG (Opens in new window) .

    GeoDCAT-AP (Opens in new window) it is also an extension of DCAT-AP that enables the search data through several portals of data, such as those offered by the Geo-Portal INSIPIRE, for spatial data infrastructures nationally and by the geospatial community that uses standards such as ISO 19115/19139. For its development SEMIC has collaborated with the Joint Research Centre (Opens in new window) , CONNECT DG (Opens in new window) and Room of publications of the UE (Opens in new window) .
