See: http://lists.w3.org/Archives/Public/w3c-rdfcore-wg/2001Sep/0441.html ACTION: 2001-10-12#1 Pat Hayes ACTION: 2001-10-12#2 Art Barstow ACTION: 2001-10-12#3 Jos deRoos ACTION: 2001-10-12#4 Graham Klyne ACTION: 2001-10-12#5 Frank Manola ACTION: 2001-10-12#6 Jos deRoos ACTION: 2001-10-12#7 Sergey Melnik CONFIRMED. 7: Propose approve parseType test cases See: http://www.w3.org/2000/10/rdf-tests/rdfcore/rdfms-parseType/ This introduced the question of whether or not unrecognized attributes in the RDF namespace are legal. RESOLVED: will postpone approval until the treatment of unrecognized attributes in RDF namespace is resolved. ACTION: 2001-10-19#1, DaveB, ensure there is a syntax document issue dealing with unrecognized attributes in the RDF namespace. 8: Propose approve domain and range test cases 1, 2 and 3 Review status of test case 4 See: http://www.w3.org/2000/10/rdf-tests/rdfcore/rdfs-domain-and-range RESOLVED: test cases 1 and 2 are approved. RESOLVED: consideration of test cases 3 and 4 is postponed, pending definition of how we do entailment. 9: Issue rdfms-identity-anon-resources Propose that the WG RESOLVE that the RDF model theory draft of 25 September 2001 (http://www.w3.org/TR/2001/WD-rdf-mt-20010925/) adequately addresses the issue http://www.w3.org/2000/03/rdf-tracking/#rdfms-identity-anon-resources See: http://www.w3.org/TR/2001/WD-rdf-mt-20010925/ There was some concern about the motivation for this issue, so it went to a vote of those present. Passed with 10 in favour, 3 abstain. For details of vote, see: http://ilrt.org/discovery/chatlogs/rdfcore/2001-10-19#T14-19-28 10: Propose approve test cases in http://www.w3.org/2000/10/rdf-tests/rdfcore/rdfms-identity-anon-resources/ See: http://www.w3.org/2000/10/rdf-tests/rdfcore/rdfms-identity-anon-resources/ These have been reviewed by Art, Jos and Graham, with no issues. RESOLVED: these test cases are approved. 11: Propose approve Pat's suggestion to distinguish between a blank node and its label. In future the term *node identifier* (which may be abbreviated to nodeId) should be used to refer label of a blank node in, for example n-triples. A node in the graph itself should be referred to as a blank node, which may be abbreviated to bNode. See: http://lists.w3.org/Archives/Public/w3c-rdfcore-wg/2001Oct/0237.html RESOLVED: This change of nomenclature is approved. 12: Review status of Entailment tests and Test manifest proposal. ACTION: 2001-10-19#2, JanG, produce proposal for next week. There was some discussion, and concerns, regarding use of TimBLs ideas for N3. For details: http://ilrt.org/discovery/chatlogs/rdfcore/2001-10-19#T14-26-46 We alspo need some test cases for a couple of issues that were resolved at the F2F meeting. ACTION: 2001-10-19#3, Jos, Create test cases for "model" issues resolved at f2f ACTION: 2001-10-19#4, ArtB, Extract text from Jos to update Test Cases WD 13: Review status of next Syntax WD Dave Becket has a document that needs to be studied and reviewed, with comments going back to the syntax subgroup. There was also discussion of how to progress Jeremy's syntax transform work. Two proposals have been mapped out, we need to decide which goes forward; pick one and debug it. ACTION: 2001-10-19#5, JanG, Aaron. Review and report on Jeremy's syntax work ACTION: 2001-10-19#6, Jan, Jeremy, Dave, Brian, Aaron, Art, SteveP, DanC. Review the syntax draft document and report back to teleconference next week. ACTION: 2001-10-19#7, EricM. Find teleconference bridge slots for next week for syntax group teleconference. There was a call for all group members to look at the syntax issues and offer comments. ACTION: 2001-10-19#8, DaveB. Email URLs of issues to be discussed/resolved 14: Review status of Schema WD DanBri has been working on this, has reflected range/domain decisions. REAWAKEN OLD ACTION: (id?) DanBri to get working version of schema spec with domain/range reflected to WG. There is still some uncertainty about the constraint resources/properties issues, though many folks seem happy to lose these. ACTION: 2001-10-19#9, DanBri. Propose resolution of constraint resources for next week ACTION: 2001-10-19#10, DanBri. ditto for constraint properties 15: Review status and technical discussion on datatypes issue See: http://lists.w3.org/Archives/Public/w3c-rdfcore-wg/2001Oct/0343.html Sergey has surveyed the approaches and tried to classify; there seem to be two broad approaches we could take. There were some attempts to clarify the two approaches in the meeting, but without too much mutual comprehension. Hence: ACTION: 2001-10-19#11, Sergey to post text attempting to state the two options, as soon as possible. DanC notes that we should also be considering test cases here, to clarify the problem space. It is generally acknowledged that this is probably THE most difficult issue the group has yet to solve. ***Meeting closed***
