- Outcomes of and actions from Boston F2F (40 min)
- Datatypes
- Issue 132 (Replace usage of "constant" with "literal" as defined by RDF and XML) resolved as per Boris's email
- Issue 126 (The list of normative datatypes should be revisited) resolved as per Boris's email
- We will use owl:real(Plus) as the name for the real numberline (plus "extra" values)
- The value spaces of xsd:float and xsd:double will be a subset of the value space of owl:realPlus (real numbers plus +/- inf, +/- zero, NaN). They will be discrete points in that space in line with XML Schema
- Decision on rational postponed pending decision on N-ary (don't need rational if we don't have N-ary)
- xsd:dateTime interpreted as XML Schema 1.1 time line; mandatory time zone for constants (applications may apply non-standard repairs); need to decide if this will be called xsd:dateTime or owl:dateTime (see strawpoll)
- Structural equivalence of literals based on syntactic form
- Annotations
- Bijan and Peter will produce a "specification standard" document by August 20th.
- Possible alternative based on Alan's proposal and Boris and Peter's paper
- Profiles
- N-ary
- Bijan (?) will produce a "specification standard" document describing N-ary datatypes (see strawpoll)
- WG will decide how much of this doc to include in main spec (from zero to all)
- Anything left in N-ary document will be "optional" (roughly: MAY be supported; if supported SHOULD be as per this doc)
- OWL Full
- Already have a good draft of RDF-based Semantics; will be frozen for review by 19th August
- Reviews from Jie, Peter and Zhe by 22nd August
- Resolved to publish on or around 1st September
- MOF Metamodel (see slides)
- Generally liked, but some issues need more thought
- Probably add it an an appendix to the syntax document
- User Facing Documents
- Reviewed snapshot of Quick Reference; still incomplete and not in card format
- Deb and Elisa to produce reasonably complete PDF by first week of September
- Reviewed first draft of Requirements
- Good progress made; Vipul, Evan, Christine and Jie to update (making shorter and tighter) within four weeks
- Reviewed snapshot of Quick Reference; still incomplete and not in card format
- Test Cases
- Some changes to test types needed (e.g., profiles tests)
- Hope to have OWL-1 tests imported into wiki within 2-3 weeks
- Manchester syntax
- Idea is to publish as a note (not rec track)
- Publication Schedule
- On or about 15th September, publish new public working drafts of core docs, including: Syntax, Semantics, RDF-based Semantics, Mapping to RDF, Profiles, XML Syntax
- plus, maybe, Primer, other UFDs
- Reviews needed of all the above documents
- reviews due by 8 September
- Goal is to transition to last call at Cannes F2F in late October
- On or about 15th September, publish new public working drafts of core docs, including: Syntax, Semantics, RDF-based Semantics, Mapping to RDF, Profiles, XML Syntax
