Decisions

• log DaveB's proposal for issue faq-html-compliance was approved and this issue closed
• log The WG agreed the following resolution of rdfs-isDefinedBy-semantics and closed this issue:

  This property indicates a resource which contains information about the subject. Often, this property is used to indicate the source of the subject uriref, where its owner specifies its intended meaning. The subject node of this property can be any uriref, and the value may be any document or resource; the usage is not restricted to a particular form or schema

• log The WG agreed to drop the requirement from M&S that "In RDF, each predicate used in a statement must be identified with exactly one namespace, or schema." because there is no concept of a namespace or schema in the RDF model.
• log The WG agreed to modify the exisiting RDF and RDFS namespaces rather than create new ones and seek implementor feedback on this decision. The WG agreed this closes issue rdf-namespace-change.
• log The WG agreed to defer schema document editorial issues to the editor and close rdfs-editorial.
• log The WG agreed to define a computable function on URIREFs which will return one of two values, light or dark. A statement with a property whose URIREF is mapped to dark by this function is invisible to the model theory; it has no semantics. The WG agreed to postpone issue rdf-contexts to a future WG.
• log The WG decided to send a short email to www-rdf-interest and others in the RDF community soliciting input on the tidy/untidy decision.
• log The WG decided that the RDF graph syntax does not allow isolated nodes in the graph.
• log The WG approved Jeremy's text on character normalization:

  Jeremy proposes to allow any XML literal in well-formed graph, and note that interperability problems may result if not using XML normalization rules

• log The WG decided that a description of RDF(S) semantics in Lbase should be added as a non-normative appendix to the model theory document (provided it is ready in time) which should be renamed RDF Formal Semantics (or similar). Lbase will be published as a w3c note.
• log The WG decided to consider producing a new document to describe the RDF graph, possibly called "Resource Description Framework". This will include description of the graph synax, what it means to assert, character normalization and possibly some other material from the primer. Graham and Jeremy to be editors.
• log The WG decided that bwm will be "series editor" for the WG documents.
• log The WG decided to aim for last call on 26th Aug 2002.
