-----------
- 15 elements
- decentralised community extension
- usage board endorsement ('ratification') of extensions
- multilingual RDF schema annotations of DC (and related) property/class definitions
(use case: 'find me the french description of dc:title...')
- history:
old DC RDF spec didn't really use RDF Schema, so instance data
had to do all the work of expressing extensions/qualifications
current DC RDF qualifier spec makes richer use of RDF, ie.
sub-property, classes etc
current concerns:
"RDF 'versus' XML"
Being processable as XML and as RDF
perceived syntactic ugliness or overhead of RDF syntax
containers: what does dc:creator(foo,bar) mean if bar is an rdf:Seq?
datatyping: people want numbers, dates (creation date of document etc)
what we like:
- loose common structure is making distributed collaboration feasible:
RSS 1.0 uses DC without the two groups having to agree a common DTD
- easy composition: rdf allows data mixing
what we need...: something soon...
