BRISTOL FTF Draft agenda: http://lists.w3.org/Archives/Public/public-swbp-wg/2004Oct/0094.html Change start times? http://lists.w3.org/Archives/Public/public-swbp-wg/2004Oct/0092.html Telecon time change to 16:14-18:00 Second day moved to account for heavy traffic. Starting at 9:30. 4. ODM / UML ONTOLOGY PROFILE See Evan's message: http://lists.w3.org/Archives/Public/public-swbp-wg/2004Sep/0044.html Update: http://lists.w3.org/Archives/Public/public-swbp-wg/2004Oct/0087.html Dan Chang of IBM joins telecon. Guus: status of xml presentation syntax: a note and not part of recommendation DanC: originally thought to use DL as core of metamodel, but have decided not to Dan: for revised submission, ODM will have metamodel(s), UML profiles, metamodel mappings Dan: also XML schemas Dan: currently design is based on ontology definition languages like RDF, OWL, topic maps Dan: "modeling" needs served by UML Dan: metamodel for RDFS, OWL (which extends RDFS metamodel), topicmap Dan: metamodel for SCL, and ER as well Guus: is it possible, e.g. for something in ER metamodel to have mappings to other metamodels? Dan: yes. We use OWL full as the core, with mappings in/out to the others Dan: also a mapping from OWL Full to UML Dan: team members for topic maps Lewis Hart from at&t Gary: Why these languages, and languages that are out of scope? Dan: RFP only talks about OWL DL, and "probably" should address others, and defines ontology as a spectrum Dan: group added SCL and topic maps, and ER, for some reasons guus: express is also a useful language from the STEP community Dan: yes - there has been some communication but it came too late for this version Dan: deadline from OMG extended to January AlanR: why backing off from DL? Dan: OWL Full anchor point for mappings Dan: mainly because OWL Dl is a subset of OWL full Gary: concerned that mapping from OWL Full to OWL DL may not be straighforward Dan: intend to use "OCL constraints" to distinguish between OWL DL and OWL Full AlanR: certain mappings to OWL Full will not reduce smoothly to OWL DL Alanr: OWL DL is not the standard DL description, as it does not have qualified cardinality constraints Dan: ODM team not the best one to address that Jeremy: will the UML <-> OWL mappings be useful for legacy migration of UML models of systems to OWL? Dan: Main purpose of mappings is to use UML tools to model and generate OWL, RDF, topic maps... Dan: But another purpose is to leverage existing UML models, so, yes Dan: people interested in that should look at our proposal and give us feedback ChrisW: suggests that SCL would be the better choice for "anchor" point than OWL Full - that's waht SCL was designed for. Dan states that mapping will be done in tables for January Dan: mappings will be expressed using OMG's QVT spec Guus asked about how the metamodel may effect the profile Dan: properties will become stereotype MOF associations Dan: we use class construct to define "user defined" properties Dan: subclass are MOF meta associations Dan: by end of Nov., first complete draft by end of Nov. guus: we will schedule some time in advance to work on that Dan: the OMG process will allow more time, maybe another year, to refine after Jan., and interact Group thanks Dan Chang for his participation and cooperation. 5. COMMENTS TO DAWG ON RDF DATA ACCESS, XQUERY, RULES See thread starting with: http://lists.w3.org/Archives/Public/public-swbp-wg/2004Oct/0114.html THis agendum moved to f2f due to time. 6. TF UPDATES (5-10 min each) All TF leaders: please also reflect on status of FTF goals: Background: Guus' proposals: http://lists.w3.org/Archives/Public/public-swbp-wg/2004Aug/0109.html 6.1 OEP (Deb), Chris) Web page: http://www.w3.org/2001/sw/BestPractices/OEP/ Chris breifly summarizes state of TF, as shown on web page. Units and Measures: editor candidate likely to be rejected by W3C as WG member. This will need f2f discussion. A lot of requests for this note, need to determine how to move forward. This will be the principle item discussed at f2f during the OEP section (during telecon). 6.2 PORT (Alistair) Ftf documents http://lists.w3.org/Archives/Public/public-swbp-wg/2004Oct/0115.html 6.3 WordNet (Aldo) no progress at the moment Improtant to have something for f2f. 6.4 XML Schema datatypes (Jeremey) Note sketch: http://lists.w3.org/Archives/Public/public-swbp-wg/2004Oct/0152.html jeremy has produced a draft note for f2f discussion guus: relation between OEP numeric ranges note and XMLS datatypes action: guus send jeremy pointer about numeric ranges and XMLS 6.5 Vocabulary management (TomB) draft and various other documents available for f2f discussion Tom: draft indicates what contributions people can make. Would like to make it a wiki and have WG members follow guidelines to make contributions. Tom: seeking feedback on outline or process. Need some guidance on putting in wiki Messages from Tom: Time line: http://lists.w3.org/Archives/Public/public-swbp-wg/2004Oct/0147.html Draft: http://lists.w3.org/Archives/Public/public-swbp-wg/2004Oct/0148.html Outline: http://lists.w3.org/Archives/Public/public-swbp-wg/2004Oct/0149.html Roles TF members: http://lists.w3.org/Archives/Public/public-swbp-wg/2004Oct/0150.html 6.6 HTML (Ben) Like WN also close to finishing but haven't produced f2f info jjc: telecon last fri, another 2morrow, jjc: discuss latest metadata module ACTION: jjc to send around pointers on HTML TF 6.7 ADTF (Libby) libby posts link to latest work http://bender.ilrt.bris.ac.uk:8080/web/servlet/Entry?action=v libby: using DOPE very easy to add ACTION: libby to send pointers to list in preparation for f2f 6.8 Tutorial Page (TomA) TomA some links coming, including ISWC guus: tutorial page not on f2f agenda. Should we consider it? TomA: i wont be at f2f, will post questions to list 7. AOB Meeting adjourned at 15:38
