RE: [semweb-dev] PA comments on rnews 0.5
- It's nice to see RDFa borrowing those two mechanisms (vocab and
profile) from the IPTC G2 Standards, albeit renaming them. It
is said that imitation is the best form of flattery.

with the vocab attribute to specify a unique schema/ontology where the
terms are defined.
But, more interestingly, RDFa has also introduced the profile attribute.
The profile attribute has for value a URI pointing to a profile that may
contain prefixes for a number of well known other vocabularies.
Therefore, we could imagine that IPTC has an official "profile" listing
all interesting vocabularies in the rNews context (i.e. the vocabularies
for which you establish some mappings) and simply recommend this profile
to be able to benefit from the whole Semantic Web.

introduced a number of structural elements (header, footer, nav, aside,
section, article) which adds a bit of semantics to how content is
organized in an HTML page ... but we are still far from the semantics of
those terms in the journalism domain I think.
