     * Outcomes of and actions from Boston F2F (40 min)
           o 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
           o 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
           o Profiles
                 + Issue 108 (Need to name the OWL Profiles); see  
proposal to resolve
                 + Issue 131 (We should unify OWL-R DL and OWL-R Full  
profiles); see strawpoll
                 + Issue 111 (There's no way to signal the intended  
semantics of an OWL document); see strawpoll
           o 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)
           o 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
           o MOF Metamodel (see slides)
                 + Generally liked, but some issues need more thought
                 + Probably add it an an appendix to the syntax document
           o 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
           o Test Cases
                 + Some changes to test types needed (e.g., profiles  
                 + Hope to have OWL-1 tests imported into wiki within  
2-3 weeks
           o Manchester syntax
                 + Idea is to publish as a note (not rec track)
           o 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

                 + Issue 109 What is the namespace for elements and  
attributes in the XML serialization?
                 + Issue 130 Conformance, warnings, errors
                 + Issue 104 OWL 1.1 DL does not have a disallowed  
                 + Issue 118 Should bNodes in OWL 2 DL have  
existential or skolem semantics?
                 + Issue 129 Desirable to have rdf:list vocabulary  
available for use in modeling in OWL 2
