Super Catalogues#

You can utilise the DCAT-AP fields dct:hasPart and dct:isPartOf to organise your catalogues within a designated super catalogue. A super catalogue should include dct:hasPart field to list all the catalogues that belong to it. Similarly, a catalogue should have a dct:isPartOf field to establish a link with its corresponding super catalogue, if applicable. Note that:

  • A super catalogue can contain N catalogues.
  • A super catalogue cannot contain other super catalogues.
  • A super catalogue cannot contain datasets.
  • Each catalogue can only belong to 1 super catalogue.
  • A catalogue does not have to belong to a super catalogue.

The diagram below illustrates the limitation discussed above:
