ISSUE-39 (rdfa term mapping triples): Profiles, term mappings, and URIs as literals [RDFa 1.1 Core]

http://www.w3.org/2010/02/rdfa/track/issues/39

Raised by: Manu Sporny
On product: RDFa 1.1 Core

>From Richard Cyganiak:

This is a comment on Profiles in the latest RDFa WD [1]. The draft provides a mechanism for establishing term mappings using RDF triples of the following general shape:

    ?x rdfa:term "name" .
    ?x rdfa:uri "http://xmlns.com/foaf/0.1/name" .

I ask that the mechanism be changed to the following form:

    <http://xmlns.com/foaf/0.1/name> rdfa:term "name" .

This change should be made for the following reasons:

1. Conciseness. If one triple is enough to say it, there should be one triple.

2. Putting URIs into RDF literals is almost always an anti-pattern.

3. The principle of least surprise.

4. Using a URI simplifies the creation of self-contained profiles that contain a set of term mappings along with labels for the classes and properties, mappings to other vocabularies, presentation hints etc.

5. Using a URI simplifies the extension of existing RDF Schema documents (e.g., the RDF version of the FOAF spec) to RDFa profiles.
