VO10 - values for dct:format and dcat:mediaType

Published on: 07/04/2015

The current version of the Application Profile mandates the use of http://publications.europa.eu/mdr/authority/file-type/ for both dct:format and dcat:mediaType. It is proposed that the values for dct:format are taken from the MDR file type NAL and the values for dcat:mediaType are taken from the IANA register as specified at http://www.w3.org/TR/vocab-dcat/#Property:distribution_media_type.

For dcat:mediaType can use http://publications.europa.eu/mdr/authority/file-type/  this table covers all the IANA register and has some additional values used by european institutions

Publications Office created a new table : http://publications.europa.eu/mdr/authority/product-form to use with dct:format

The proposal is to use the MDR File type NAL for dct:format and the IANA medfia types for dcat:mediatype. The latter case may need to be done with blank nodes as there is no URI set for IANA media types.

The recommendation to use IANA file types in dcat:mediaType and MDR File types NAL in dct:format is in Draft 3.

The URIs for the dcat:mediaType by the Publications Office are not dereferenced. E.g., the URI for ZIP returns a 404: http://publications.europa.eu/resource/authority/file-type/ZIP. Any idea whether there are plans to dereference these? If not, we should not use them?

Assigning this issue to Willem van Gemert at Publications Office.

De-referencability of the authority tables on table and concept level is in the pipeline.

For the moment only the authority tables are de-referencable, not the concepts contained in the tables. Re-users have to indicate the desired mimetype (e.g. application/rdf+xml).


The following request will return the SKOS:

curl -L -v --header "Accept: application/rdf+xml" http://publications.europa.eu/resource/authority/language


We hope to migrate the authority tables in the course of this year to the CELLAR, the Content and Metadata Repository of the Publications Office. I will check with the CELLAR team if concepts are de-referencable once they are available in the CELLAR or if an additional development is required.

Meeting with CELLAR team scheduled for this Thursday 11 June to discuss planning for de-referencability of concepts.
