CatPrez is the Catalogue Presentation tool - a read-only Linked Data interface for the online delivery of Data Catalog Vocabulary (DCAT) - Version 2 catalogs.

CatPrez is one of the only, perhaps the only, DCAT2-native catalogue.

It is based on the pyLDAPI toolkit that implements the Content Negotiation by Profile W3C & IETF candidate standard for Internet-based content retrieval according to data specifications (profiles).

  2. DGGS Catalogue - a listing of information assets relevant to the OGC ‘s Testbed 16 Discrete Global Grid experiments
