<ChrisW> ACTION:* Frank will do the scenarios for information integration with Ed Barkmeyer assisting [CONTINUED] [recorded in http://www.w3.org/2006/02/07-rif-minutes.html#action10]

<PaulaP> Paul is on the call, but not on irc

<ChrisW> ACTION:* Paul Vincent will do the detailed scenario for "Interoperability between rule engines" [CONTINUED] [recorded in http://www.w3.org/2006/02/07-rif-minutes.html#action11]

PaulV scenario for Interop between rule engines is currently evaluated by Allen & David -- was sent only 10 mins before call: CONTINUED.

Discussion on State of UCR document:

David: Recent input. Condensed subsections for each generalized uc category. Generalized uc on publication has not changed much, since only 2 concrete uc's were there; now with csma's uc it is more complete. Other subsections are being condensed as well.

Allen: Credit scenario (2.4) changed; have a look at that.

<scribe> ACTION: Donald, Said, John: Scenario where RIF enters the play. [recorded in http://www.w3.org/2006/02/07-rif-minutes.html#action12]

<ChrisW> ACTION: Donald, Said, John: provide scenario for human-oriented use case showing where RIF is used [recorded in http://www.w3.org/2006/02/07-rif-minutes.html#action13]

Harold: When omitting larger portions of material, can they still be linked?

David: Difficult, if final document should be self-contained.

Sandro: Perhaps no technical/organizational/editorial problem to provide links.

csma: Stand-alone has advantages. If you think something valuable was omitted, say it now or soon.

Allen: With the many changesr/restructuring it was hard to keep all links at all times; just wanted to work from one place in the document; links can be brought back on one of the document pages, so people would still find them; could also contain reqs etc., but would be separate from main document.

Sandro: Not sure what you exactly mean. But yes, we can still bring links back from such a special document page later.

csma: People should offer ways to insert what they want to have in. Better than just linking to things. We should have all material now. Can we have a new draft soon?

Allen: Waiting only for Donald, Said, John's uc explanation wrt RIF.

David: Unless we enumerate all individual reqs, we cannot see the global req; so iterative process needed. Allen and I don't see exact distinction between design goals and reqs.

Allen: Ties in with discussion on what RIF is and isn't.

csma: "Should RIF be executable?" discussion, for instance.

Allen: Right. Partly motivated by OWL's UCR document; answers question "What's an ontology?".

<ChrisW> the owl docuemtn says what is an ontology, then the RIF document shoudl say what is a rule

<FrankMcCabe> I think that the design goals for the RIF is something that should be figured out by the whol group

<ChrisW> not what is a RIF

Allen: Peter and Francois want to see RIF be executable, which is fine. But: What about interchange between overlapping languages -- we need a discussion, as a group.

<ChrisW> (just looking at the analogy)

<saidtabet> how about the analogy with HTML and HTTP? Language versus Protocol

<pfps> Hmm, I wouldn't say that my "requirement" is that the RIF be executable - however, forbidding it from being executable is not something that I can sign on to.

csma: Discussion not easy on the telecon. Mailing list discussion is unfolding well. Will need to come to a conclusion at one point. Are there any other issues that need to come in? E.g.: Data access, linked to issue of query languages.

<scribe> ACTION: csma will incite this broader discussion on mailing list. [recorded in http://www.w3.org/2006/02/07-rif-minutes.html#action14]

David: Should we have an action for everyone look over what we have?

csma: Prefer that next week someone summarizes consensus on design goals.

Allen: People who say RIF should be executable, what do they think this means for interchange/interop? E.g.: Maybe executability even supports interchange/interop.?

csma: People with further high-level design goals should propose them on mailing list.

David: Would be nice to have backlinks from reqs to uc's.

<PaulaP> requirements from the original use cases or from the categories?

csma: The original, concrete ones. Who could copy all req sections from all uc's into one document for next week?

<PaulaP> I can do that

<scribe> ACTION: Paula will do this, removing duplicates if time permits. [recorded in http://www.w3.org/2006/02/07-rif-minutes.html#action15]

<PaulaP> ok

Donald: Will bring in new reqs via posting/email.

<ChrisW> ACTION: Paula to copy all requirements from original use cases into a single place, removing duplicates and pointing back to originals [recorded in http://www.w3.org/2006/02/07-rif-minutes.html#action16]

David: Paula, please put it at the 'source' section to begin with.

Classification

<ChrisW> ACTION:* Harold will explain what Lloyd Topor extensions etc mean [DONE] [recorded in http://www.w3.org/2006/02/07-rif-minutes.html#action17]

Harold: See http://lists.w3.org/Archives/Public/public-rif-wg/2006Feb/0019.html

ChrisW: Fine, DONE.

ChrisW: Re Discussion RIFRAF and uc's: Which parts are relevant for phase 1? Example: bNodes -- one idea for them is going beyond Horn logic: so are they not phase 1? Generally, answer to "What goes into phase 1 / phase 2?" may not be a crisp one.

<josb> should we have a mailing list discussion on this topic: which features belong to phase 1?

ChrisW: So we need to decide, as a group, that, in the 1st year, we will or will not deal with some issues.

csma: What is the impact of phase 1 / 2 on rule interchange reqs? A prioritized list?

ChrisW: Yes.

csma: Should we add a "phase 1 / 2" column to the List of Systems?

ChrisW: Yes.

Sandro: Re Procedure: Always ask if all understand what people's action is supposed to be.

<DaveReynolds> +1 to Sandro

<PaulaP> +1 to Sandro' comment

<sandro> http://www.w3.org/2005/rules/wg/wiki/List_of_Rule_Systems

csma: For people who have entered a system, they should enter what the phase 1 / 2 impact is. Interop impact?

Sandro: Hard to imagine they wouldn't all have non-Horn features

csma: Example: For JRules system translated a few rules into logic notation to make them comparable with other systems.

Chris: Will start this action.

<ChrisW> ACTION: Chris to start email discussion about what issues are "fuzzy" wrt phase 1 & 2 [recorded in http://www.w3.org/2006/02/07-rif-minutes.html#action18]

<ChrisW> ACTION: JosDeBruijn create a wiki page explaining the issue with bNode semantics and summarize the possible solutions which have come up during the discussions on the mailing listat Lloyd Topor extensions etc mean [DONE] [recorded in http://www.w3.org/2006/02/07-rif-minutes.html#action19]

OWL & RDF Compatibility

<sandro> JosB's page: http://www.w3.org/2005/rules/wg/wiki/bNode_Semantics

csma: E.g., when you discuss bNodes in the head, you should say why it's important for interchange.

<josb> apologies, my connection is failing me

ChrisW: Josb action is DONE.

Sandro: Don't see anything time-critical here -- cannot go too far ahead of design discussion.

<MarkusK> ACTION 17 = JosDeBruijn create a wiki page explaining the issue with bNode semantics and summarize the possible solutions which have come up during the discussions on the mailing list [DONE]

csma: Question of interchange of human-oriented syntax related to OWL & RDF: Could you write terms and facts in OWL & RDF?

Donald (and Said): Yes, will discuss OWL & RDF applicability to our human-oriented uc.

Sandro: bNode action can be removed from future agendas, but people can of course still bring in any new aspects about this.
At some point bNodes will come up again as a design decision when we'll have to make a choice.
