DCAT Access of CKAN repositories
[Introduction](DCAT Access of CKAN repositories#introduction)
[Catalogs interoperability](DCAT Access of CKAN repositories#catalogs-interoperability)
It is possible to fetch information about a specific dataset as rdf with dcat vocabulary by just adding '.rdf' to the url. So if the url is this
https://data.gov.uk/dataset/road-accidents-safety-data
we can easily obtain the rdf: https://data.gov.uk/dataset/road-accidents-safety-data.rdf
but dcat translation might be old. OKFN is working on an extension of CKAN called CKANEXT-DCAT to address the issue. Jackan currently implements a translator to DCAT following CKANEXT-DCAT, see Jackan user docs
Note there is yet-another 'ckan to dcat' mapping specified in new EU open data portal Data supplier guidelines (sic):
can be found in section Providing data -> be harvested by us
In the dataprotocols.org website, there is a link to Data Catalog Interoperability Protoco (DCIP) which looks interesting. It defines REST apis to get datasets list from a catalog with a DCAT vocabulary. At the moment of this writing the spec is at 1.0-beta.2 . Might be in the future CKAN will adopt it, we should check it.
