Hello RDFa WG members,
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.
Best,
Richard
