JimH: so our ftf schedule looks complete ACTION JimH: update ftf schedule on group home page. > 2) Action item review (10 min; Hendler) [some of these were reviewed last time, but the chair wasn't sure from the record] > Actions Jan 31: DONE: Finin to complete use case on ubiq. comp (Due ASAP) DONE: Buswell to complete design Use case (Due ASAP) DONE: - Obrst to help find ontology partitioning - review and refine req (Due ASAP) DONE: - Pat Hayes to send Jeff a couple of sentences on referring to vs. commiting to ontologies (Due ASAP) DONE: Tim Finin to send Jeff a paointer to the FIPA langauge req. document (due ASAP) WITHDRAWN: Use Case group will have one more week to get a draft to group as a strawman. WITHDRAWN: - have unwritten parts in the D+O vs OWL document done as soon as possible (Mike, Dan, Ian) -- follow on... DONE: Mike D. to document what OWL reqs not covered by D+O, and what D+O features currently not used in addressing our reqs - Due: Feb 7 ACTION CONTINUES: Jim/Guus will send to mailing list a proposed list of documents/outputs expected of the working group (tied to calendar if possible) and ask people to express interests in particular w/respect to those issues 3) Requirements Document (30 min. Heflin, Dale, Volz) cf * REQDOC: New Draft Jeff Heflin (Wed, Feb 20 2002) http://lists.w3.org/Archives/Public/www-webont-wg/2002Feb/0193.html We discussed issues identified by the editor... 1) "Referencing with URIs" as raised by Peter Patel-Schneider. JimH: one point you raised was with the term "URI" in particular [as opposed to "URI reference"] JimH: another was the general architectual principle of using URIs for terms Pfps: due to "brokenness", URIs aren't sufficient to reference everything I'm interested in [ e.g. schema components] (move on while we hunt the archive...) -- 3) "Ability to state closed worlds. Jeff: it was suggested to demote this to an objective, but PatH argued for it as a requirement. IanH: seems too vague in the requirements document. JeffH: demoting it to an objective doesn't mean "we won't touch it" PatH: OK. IanH: "certain topics" in particular isn't sufficiently precise ?: complete elements of a class seems easier. RESOLVED: to make it an objective, incorprating editorial suggestions [e.g. from Frank] -- 4) "Properties for statements / Reification / Tagging" Jeff: Peter objected to this as a requirement, but other folks disagreed. JimH: at the ftf, this got an A, no? e.g. where a statement came from ... in the draft, "Associating properties with statements", section 4. http://km.aifb.uni-karlsruhe.de/owl/ connolly agrees with demoting this to an objective. Frankv: this is about the "lightweight version"; ala rdfs:label... borden thinks this should go for further discussion, agrees with as objective PatH: [... think I missed it... if it was important, please clarify, Pat] MikeDean: "statements about statments"? hmm... maybe not... PROPOSED: make it an objective. some objection. DanCon: I don't intend to argue for something as a requirement until I've seen a design for it -- not a design that the whole WG necessarily agrees to, but one that tells me we can meet the requirement this year. Have folks in favor of this seen designs they like? [several] yes. At this point, we preempted the discussion of issues to discuss the schedule... ====== REQDOC schedule JimH: I'd like to get finished soon ... I think we're already late Ian: several of these seem too vague... JimH: it would be better if you had sent suggested replacement text DanCon: we can refine the wording in a subsequent draft; we can also demote requirements in the light of design experience. [detailed schedule...] Lynn: the document changed substantively yesterday JimH: it seems very useful to get our use cases out to the community I don't see issues with the use cases... are we OK with that? LynnS: much of my comments are about the use cases JimH: how about this as a schedule... a new draft monday, with diff marks... [...] Lynn: what about publishing it as is? DanC: who has issues with draft but is willing to publish? PPS: unpublishable as is. PatH: what are requirements to publish? DanC: I wouldn't having the editor sprinkle 7-8 "no consensus here" notes and publish. JonB agrees on publication next week JimH: I think there are editorial issues where we're happy for the editor to make those changes... JimH: I'd like to release a document [a week?] [oops.. scribe got lost here] LynnS: Dissents, wishes to release WD now, extra week won't be enough to substantially improve [agenda check: postpone implementation discussion? OK.] JimH: we'll take a shot at resolving the issues identified by the editor during this telcon, then we'll go. NOTE WELL: JimH: at this point, folks who want changes, include replacement text. RESOLVED: new draft monday (incorpriating editorial comments at editor's discretion). WG folks are to read the document Tue, Wed; we'll decide next thu whether to publish. ACTION Jeff: new draft monday ACTION JimH: put decision to publish on next week's agenda. ---- back to 4) "Properties for statements / Reification / Tagging" PatH volunteers to propose wording for this item PFPS: where did this come from? Jeff: from mail from Mike Dean, and from editorial work toward overall consistency JimH: from ftf record: A Annotation/tagging of ontologies (some particular properties) ACTION PatH: propose wording for this item ------- 5) "Lexical representations" under "Lexical representations" in section 4. Jeremey: I think this came from a proposal I made... ACTION Jeremy: suggest wording. Jeremy: yes, 'lexical' is misleading. ------ 6) Removing "Integration of digital signatures." ACTION DanC: suggest wording ala "just check that our language doesn't conflict with W3C XML Sig stuff" ------- 7) Mike Dean's new requirements (dated Feb. 19). JimH: can we postpone to next draft? MikeD: ok ----- 1) "Referencing with URIs" (redux) PFPS: cf http://lists.w3.org/Archives/Public/www-webont-wg/2002Feb/0085.html PFPS: "we need to be able to reference what we're interested in [...]" JonB: pls s/URI/URI reference/ 2nded PatH: be aware of #fragment issues in RDFCore PFPS: I guess the wording, as stated is ok. RESOLVED: with the s/URI/URI reference/, it stays. [At this point, the meeting was extended; LibbyM was excused.] -------- 2) "Ontologies as resources" Jeff: PFPS argued against, DanC, Frank, etc. argued in favor. PFPS: how about "ontologies as distinct objects; ontologies must have their own unique identifiers" DanC: ok by me JonB: "object" seems just as problematic as "resource", but [I guess I could live] ?: "ontologies as distinct objects; ontologies must have their own unique identifiers, i.e. URI reference" PROPOSED:"ontologies as distinct objects; ontologies must have their own unique identifiers, e.g. URI reference" so RESOLVED, by consensus. Jeff: so that's it for the stuff as of 10:40ET last night. I'm happy to take wording (editorial) suggestions thru Fri. JimH: I'll be sure the motion to publish is in the agenda next weds. > 4) DAML+OIL comparison w/Requirements (15 min, Dean) > Report on email from Dean > How to follow up discussion (Hendler) postponed. > 5) Implementations (20 min; Connolly) > WG are expected to produce implementations as well as document. > Chairs want this activity to get started - Dan C. to discuss, solicit > volunteers. postponed. > > *** discussion postponed - Layering, Future Document List. > ----- Other business, adjournment, next meeting RESOLVED: to meet again one week hence, Thu 28 Feb 2002, per regular schedule. agenda next time: yes, MikeD's DAML eval stuff Frank vH volunteers to scribe next week. tentative regrets from DanC; regrets from PatH ADJOURNED.
