    DCAT-AP-ES implements DCAT-AP and its HVD extension, ensuring compatibility with the European open data ecosystem.

    UML

  • When does it come into effect?

    DCAT-AP-ES is expected to come into effect in 2025, following the approval of the new NTI-RISP, the day after its publication in the Official State Gazette (BOE).

    NTI-RISP

  • What is the deadline for migration?

    Publishers have an adaptation period of six months from the entry into force of the NTI-RISP.

Data Model#

  • How do the DCAT-AP-ES elements relate to each other?

    The DCAT-AP-ES model functions as a network where elements connect to each other:

    - A catalog (dcat:Catalog) serves as the main container hosting datasets and services

    - Data services (dcat:DataService) provide access to the datasets

    - Each dataset (dcat:Dataset) can have multiple distributions (formats)

    - Distributions (dcat:Distribution) can be accessed through specific services
