6: Confirm Status of Completed Actions

ACTION: 2002-09-06#4 jjc
review material thus far on specifics of rdfs:Datatype, rdfs:Literal and the abstract syntax of literals and produce a proposal for wording in the Abs. Syntax document.


ACTION: 2002-09-27#1 bwm
summarize requirements into next iteration of datatyping rationale document


ACTION: 2002-10-04#1 bwm
send message to the list re the specifics of the voting procedure


ACTION: 2002-10-04#2 bwm
help articulate a the tidy/untidy discussion  (more statement.. 'can you live with this') and ask WebOnt at f2f


7: Confirm Status of Withdrawn Actions

ACTION: 2002-06-18#12 PatH
evaluate effect on the proposed form on literals on the model theory document

ACTION: 2002-08-16#5 MikeD
Mike Dean to write-up daml:Restriction use case where external type information comes from other than rdfs:range

ACTION: 2002-09-27#2 Sergey
write up comments about changes to API implementation vs changes to applications incurred by change to RDF handling of literals. 

ACTION: 2002-10-04#3 ericm
contact the Adobe XMP folk and solicit input to the tidy/untidy debate

ACTION: 2002-10-04#4 bwm
to contact Mark Butler (CCPP) about tidy/untidy issue

8: Book Review
Shelly Powers is finishing off a book and is seeking volunteers to help review it.  She is particularly concerned about the chapter on reification.


9: LBase Document
Propose approve publication as a note.


10: Literal Abstract Syntax
Questions arising:

o Are datatypes restricted to XSD datatypes?

o Do typed literals have a language identifier?

o Does the abstract syntax require a datatype URI to refer to a
datatype and that the lexical form be from the lexical space of that

o should a parser barf if it sees a datatype for which it cannot
validate that strings are from that datatypes value space and for
which it cannot compute the lexical to value mapping

o is there a generic value entailment in the model theory:

  <a> <b> <dt1>"foo" .
  <c> <d> <dt2>"bar" .

whenever dt1.value("foo") = dt2.value(bar)?

o The n-triples form:

  <a> <b> <dt1>"foo" .

requires further parser lookahead than say:

  <a> <b> "foo"<dt1> .

The latter is easier to parse.
