This is an evolving list of topics to be discussed in breakouts and/or plenary sessions. Feel free to make these be links to new wiki pages, to add details.
2.1 Feature Changes
- Deprecations (suggest data producers avoid these)
- reification (align with some "named graph" support)
- rdf:Alt (just remove)
- rdf:Bag (fix or remove)
- rdf:Seq (use rdf:List instead)
- xs:string (use plain literals instead)
- rdf:XMLLiteral (use plain literals instead, with quoted XML)
- rdf:ID (use rdf:about instead)
- New Features
- lists as first class entities
- annotation framework
- quads, n-quads
- named graphs
- RDF API
- change BNode semantics
- adopt ter Horst semantics for RDFS
- remove restrictions on bnode as predicates
- remove restrictions on literals as subjects
- removal of all semantics for RDFS
- data constraints
2.3 Syntax and Protocols
- new XML syntax
- change propagation
- linked data radius (links + inference)
Draft text on IRIs
The Working Group will consider, in coordination with the I18N WG, the replacing of the term RDF URI Reference with an up-to-date reference to the IRI RFC.
2.4 Special Vocabularies
- unordered lists
- measurement units
- identity management
- n-ary relations
- codifying "follow your nose"
