    dependencies.

  CONTINUED (only partially done)

ACTION: 2001-06-22#3: All: Post issue priorities with reasons

  CONTINUED (need more feedback)

ACTION: 2001-06-22#4: Sergey Melnik: Summarize issue priorities that are
  posted by 9am San Francisco time, Wednesday 4th July.

  CONTINUED (after more feedback from above action)

ACTION: 2001-06-22#5: Dan Brickley: Get a draft of RDFSchema to the group.

  Discussed below as Issue #1

  DONE

ACTION: 2001-06-08#2: Dan Brickley: write up decision to allow partial
    descriptions of containers up in more detail for the list

  CONTINUED (Dan Brickley absent)


Issues discussion:

Issue #1
  http://www.w3.org/2000/03/rdf-tracking/#rdf-containers-syntax-ambiguity
  http://www.w3.org/2000/03/rdf-tracking/#rdf-containers-syntax-vs-schema

  Owner: Brian McBride

  The analysis in the meeting agenda:
    http://lists.w3.org/Archives/Public/w3c-rdfcore-wg/2001Jun/0520.html
  was accepted as closing the issue.

  ACTION: 2001-06-29#1: Brian McBride: put the writeup online.


  ISSUE CLOSED


Issue #2 
  http://www.w3.org/2000/03/rdf-tracking/#rdfms-difference-between-ID-and-about

  Owner: Aaron Swartz

  Considered Aaron's resolution in:
    http://www.blogspace.com/rdf/rdfms-difference-between-ID-and-about/

  Discussion led to revised wording from Aaron:
    Usage of an rdf:ID attribute to identify the subject of a
    description, is equivalent to usage of an rdf:about attribute
    with the same content, except the content of the rdf:about
    attribute is prefixed by a '#' character and URI encoded.

  which was mostly agreed.  Discussion of proposal for adding an
  rdfs:isDefinedIn property for every ID did not get sufficient
  consensus - to be continued on email.

  ACTION: 2001-06-29#2: Ron Daniel: post an analysis of where the
    distinction of ID and about has been used.

  ISSUE CONTINUED


Issue #3
  http://www.w3.org/2000/03/rdf-tracking/#rdfms-aboutEach-on-object

  Owner: Stephen Petschulat

  Considered his summary in:

    http://lists.w3.org/Archives/Public/w3c-rdfcore-wg/2001Jun/0386.html

  and Ora Lassila's comments in
    http://lists.w3.org/Archives/Public/www-rdf-interest/2000Dec/0011.html

  and RESOLVED that:
     rdf:aboutEach is not allowed on an rdf:Description element which
     is an object of a statement.

  ISSUE CLOSED


Issue #4 
  http://www.w3.org/2000/03/rdf-tracking/#rdfms-xml-base

  Owner: Jan Grant

  Discussed his proposal in:

    http://lists.w3.org/Archives/Public/w3c-rdfcore-wg/2001Jun/0340.html

  Brian McBride proposed the issue be postponed since Dan Brickley
  and Dan Connolly were not present and had points they wanted to raise.

  ACTION: 2001-06-29#3: Ron Daniel: post an email about how support of
    xml:base would generate different things in RDF/XML parsers.

  ISSUE CONTINUED


Any Other Business


xml:lang and literals - Brian McBride

  Presentation from Brian that xml:lang is not in the formal model
  but sort-of is from the prose and syntax and proposes that a
  literal might be at least a pair of items (string, language).

  Sergey Melnik brought up adding namespaces to the RDF model which
  is not currently recorded on the issues list.

  ACTION: 2001-06-29#4: Brian McBride: Update the
      http://www.w3.org/2000/03/rdf-tracking/#rdfms-uri-substructure
   issue to add Sergey's question:
      Namespaces are used as an abbreviation in the syntax - is it
      syntactic sugar or part of the model?

  Wide ranging discussion of literals and xml:lang - implementation
  experience, querying - see the chat log. Several strong expressions
  of support given for xml:lang as already used in applications.

  Discussion of xml:lang as a special case of more general/primitive
  data types.  Taken as a slightly separate issue left that can
  for another time since it might be more than a 1.0 clarification.

  ACTION: 2001-06-29#5: Jan Grant, Eric Miller, Martyn Horner:
    generate use cases and requirements for language (xml:lang) and
    literals.


Changing time of face-to-face meeting - Frank Manola

  Brian McBride - no, the meeting will remain 1 and 2 August 2001 as
  previously decided since several people have already booked travel
  and accommodation.


Date of next meeting:

  In one week at 2001-07-06, 10am Boston time, same place.

  To be confirmed due to US national holiday on 2001-07-04

  Eric Miller: probable regrets
