Within the program
de la Comisión Europea, la iniciativa Comunidad de Interoperabilidad Semántica ( SEMIC
) 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:
as a collection of data sets
as data collection
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.
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
and CONNECT DG
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
, CONNECT DG
and Room of publications of the UE
