Charter
Brian reviewed the
charter,
noting that backward compatibility with existing RDF is a priority.
No issues were raised with the charter,
although Frank Manola noted that the
"devil may be in the details".
Issue Discussion
We discussed 3 technical issues:
- #rdf-ns-prefix-confusion
- The XML Namespace spec doesn't address unprefixed attributes.
We'll have to live with their bug.
RESOLVED: We'll strongly recommend the use of namespace qualified attributes,
and allow but deprecate unqualified attributes.
- #rdf-container-syntax-ambiguity
-
- #rdf-container-syntax-vs-schema
-
Ora noted that it was an original requirement for RDF that
parsing should not require knowledge of the schema.
The discussion on the latter 2 issues largely occurred in parallel and
became a more general discussion about containers.
Several people advocated deprecating container types and/or making them
a separate module
(this also applies to reification).
It also brought out several larger issues:
- RDF Syntax vs. Model
- We should record more of the history behind various RDF issues.
- What is the real-world use of containers and other RDF features?
What will break if we change stuff?
ACTION (everyone): send RDF feature usage information from
real-world applications you know of to Guha, who will collect it.
- Modularization can be accomplished via namespaces or documents.
- Redefinition of the RDF(S) namespaces may not be required.
ACTION: Dan Brickley will own the "container problem". Ora Lassila will help.
Face-to-Face Meeting
W3C procedure requires 8 weeks notice for a face-to-face meeting.
RESOLVED: We'll meet August 1 and 2 in conjunction with the
International Semantic Web Workshop (SWWS)
at Stanford.
ACTION (various): Contact Brian McBride and Dan Brickley if your organization
has a facility in the Bay Area that would be willing to host a meeting of
20-25 people.
Issue Ownership
Brian asked for volunteers to "own" (analyze and write-up a suggested fix)
items on the
issues list:
- #rdfms-editorial
- Ora Lassila to own. Dan Brickley and Guha to help.
- #rdfms-reification-required
