ISSUE-27 (format): URIs for file formats [DCAT]


Raised by: Phil Archer
On product: DCAT

DCAT uses dcterms:format thus:

:distribution dcterms:format [
   a dcterms:IMT;
   rdf:value "text/csv";
   rdfs:label "CSV"

Is this the best we can do? There are alternatives:

1. Ed Summers' work on providing URIs for MIME types [1] could potentially be moved in to W3C space by this WG.

2. Ivan Herman's work on providing file types [2] could be extended ad hoc to provide a stable set of URIs for file formats that includes MIME type as one property but allows for unambiguous naming of multiple formats with a single MIME type

3. Stick with what we have.

Of these, 3 is the path of least resistance, 2 is my preferred option. This is because, as Ivan points out, the MIME type doesn't always tell you everything you need to know.  It's not that big a task and we could create a few key ones fairly quickly.
