[Mediann] Ad. "Return Type / String vs Uri" - Issue

Dear all,

I recently had a look at the Dublin Core in RDF recommendation [1] 
which could provide a solution to the return type issue that we
discussed in our last telecon [2].

In the recommendation examples to describe Dublin Core metadata in RDF
can be found [3]. Especially interesting is the use of dcterms:subject
which in Example 1 points to an URI to identifiy a value. In Example 2 a
string value and a vocabulary encoding scheme are used (this conforms to
the example from Werner Bailer which pointed out to established
classification schemes I guess). This is done using terms from the DCMI
Abstract Model [4]. In example 3 a language tagged literal is used to
specify a title.

Perhaps this is a useful best practice for the return type / String vs.
URI issue.

Do we want to create a WIKI page to discuss this issue? I guess it would
also be important to discuss for which properties this problem is relevant.

Best regards,

Tobias
