Or you want it to BE something different? 15:33:49 cmsa: have to go down to find common core, from which both HR dialect and PR dialect come 15:34:08 Harold: anyway, we have gone beyond Horn, with equality, etc. 15:34:18 what about: RIF LP dialect ? 15:34:31 Harold: "RIF Logic Dialect" 15:34:36 zakim, unmute me 15:34:36 MichaelKifer should no longer be muted 15:34:43 chris: Harold isn't saying to extend the core, merely to change the name 15:34:52 chris: since anyway, what's in core now is beyond Horn 15:35:00 Michael: "RIF Logical Core Dialect" 15:35:02 michael: that's why it makes sense to call it logic 15:35:19 cmsa: we don't want to forego idea of having one common core 15:35:58 Michael: makes sense to develop a core for logic dialects, and a core for production rule dialects, both of which come from a simpler common core 15:36:09 Perhaps use "base" - "PR Base" and "LP Base" 15:36:20 cmsa: we don't want the term core except for in the one core from which all PR and HR dialects spring forth. 15:36:36 too close to "data base" 15:36:37 you beat me, Dave, I was just going to suggest "base" :-) 15:36:38 +1 Dave 15:36:51 "RIF Logic Base Dialect" 15:37:02 cmsa: base too close to database 15:37:10 foundation? 15:37:14 "RIF Logic Basis" 15:37:24 "RIF Basic Logic Dialect" 15:37:25 PROPOSED: To better understand what RIF Core could be, create two task forces in RIF, one focusing on a Logic Basis and one focusing on a PR Basis. 15:38:10 "RIF Basic Logic Dialect" 15:38:18 "RIF Basic PR Dialect" 15:38:19 ? 15:38:28 cmsa: to Michael --- you're not proposing to extend the basis logic dialect?

AOB [from csma] 15:52:18 sandro: One firm requirement: (Missed it) 15:52:46 sandro: could pick a language that was a subset of rdf/xml,. allowing use of rdf tools. 15:53:16 sandro: harold pointed out one flaw in the way rdf does data types (check) 15:53:33 q? 15:53:39 q+ 15:53:43 sandro: good to aim for both communities 15:54:05 cmsa: didn't see relationship between xml syntax strawman and rif serizalizatoin strawman sent out yesterday 15:54:40 sandro: mapping from asm to xml schema 15:54:50 sandro: and mapping from the instance level 15:55:08 sandro: those 2 mappings are strongly connected, inform each other, 15:55:27 sandro: but don't subsume (??) one another 15:57:48 cmsa: in oo language like ilog, and many java pr engine, we would have a rif object model conforming with asn syntax, systematically derived from xml syntax, mapping would not go from internal model for rules in engine to xml, but from internal representation in engine to abstract asn representation to xml document. 15:58:16 cmsa: in that view, don't think we need rif syntax data structure that Sandro proposed 15:59:12 s/from asm/from asn/ 15:59:48 zakim, unmute me 15:59:48 LeoraMorgenstern should no longer be muted 16:01:30 cmsa: I would expect that: xml syntax for rif dialect is concrete syntax for that rif dialect. 16:01:39 cmsa: asn is abstract syntax for that same dialect. 16:02:01 cmsa: so i understand the first xml syntax strawman because I understand how to derive xml syntax from asn abstract syntax 16:02:14 cmsa: where asn syntax has classes like rules, ifx, onditions, 16:02:48 cmsa: but now, in the serizalization strawman, I see yet another syntax for rif, w.ith not of these abstract concepts. 16:03:12 zakim, unmute me 16:03:12 MichaelKifer should no longer be muted 16:03:13 sandro: let's forget about the serialization strawman for now, then. 16:03:22 sandro: I can go back to the way I was talking to it before. 16:03:33 michael: similar question to sandro's 16:03:46 michael: what' s the advantage of using the xml syntax? Just that you can use rdf tools? 16:03:58 michael: that's kind of vague ... what problem are we trying to solve? 16:04:05 zakim, mute me 16:04:05 LeoraMorgenstern should now be muted 16:04:17 csma has joined #rif 16:04:33 michael: and what are the advantage of your soluiton? 16:04:44 michael: I'm having difficulty understanding what it's all about? 16:05:07 cmsa: doesn't undersatnd michael's question 16:05:24 sanddro: michael thinks that inthe core doc, there's already a start at xml syntax 16:05:30 sandro: there isn't an existing syntax 16:05:37 q? 16:05:40 michael: yes, there's something 16:05:47 sandro: but it doesn't give datatypes 16:05:54 ack michaelk 16:05:54 sandro: not in the examples 16:06:05 michael: so, yes, we should do it better 16:06:20 sandro: so that's what I'm trying to do, to nail all that stuff down, and use what another working group has spent years working on. 16:06:30 stuff like "$49" and "LeRif" 16:06:47 cmsa: in the wd, there are proposals for xml syntax, but they haven't been furthered. 16:07:32 cmsa: question is not just: what is xml syntax for the current draft, but how do we derive the xml syntax. 16:07:40 the problem is we need some simple rules to transform a syntax in asn to a syntax in xml schema 16:08:03 We already had discussed solutions for "$49" and "LeRif" here: http://www.w3.org/2005/rules/wg/wiki/A.1.1_Basis%3A_Positive_Conditions_over_Bipartitioned_Constants 16:08:09 cmsa: regarding why xml/rd rather than not-rdf xml: if it gives us the possibility to use both kinds of tools, so that both rdf people and xml people can stay in their worlds, what's the drawback? 16:08:34 the question is whether rdf/xml helps or hinders the solution to the problem 16:08:39 q? 16:08:55 sandro: up to members of the working group to advocate for the tools they want to use. 16:09:19 JAXB 16:09:36 acronym for Java API for Xml Binding 16:09:57 sandro: for example, gary has advocated for JAXB. 16:10:50 q- 16:10:53 zakim, mute me 16:10:53 MichaelKifer should now be muted 16:11:02 pretty much any legal xml schema will "work" for jaxb, but it could yield a very cumbersome api 16:11:17 http://lists.w3.org/Archives/Public/public-rif-wg/2007Jul/0058.html 16:11:34 Action on Gary to check whether there would be problems with JAXB if the xml syntax would be derived from the asn in the email posted above? 16:11:56 cmsa: Gary, problem hidden in the translator? 16:12:41 The translator would also need to be maintained, as we develop RIF through its lifecyle. 16:14:41 Gary: some confusion about how the translation would work .. .. don't know enough now to produce the translation ... 16:15:07 cmsa: Sandro, can you clarify this for Gary? 16:15:33 zakkim, unmute me 16:15:38 ACTION: Sandro to produce XML Schema following his Serialization Strawman proposal -- due Julu 27 16:15:38 Created ACTION-328 - Produce XML Schema following his Serialization Strawman proposal -- due Julu 27 [on Sandro Hawke - due 2007-07-24]. 16:15:44 I have to leave the call. 16:15:48 zakim, mute me 16:15:48 LeoraMorgenstern was already muted, LeoraMorgenstern 16:15:58 -ChrisW 16:16:00 I noticed asn07 now being often mentioned in the discussion instead of asn06, although at F2F6 I heard asn07 was still purely experimental. 16:16:25 cmsa: there were a number of side discussions ... 16:17:03 cmsa: (you (Sandro?)) proposed that the root of the document should be one thing, Harold, that it should be another 16:17:44 Sandro: still useful to try to have this in RDF, but I know Harold doesn't agree. 16:17:45 rdf:RDF to rif:RIF 16:18:06 Harold: it should be mappable to RDF 16:18:29 q+ 16:19:23 cmsa: we need to find a use case where the fact htat it is rdf xml and not pure xml is a problem. 16:19:29 q? 16:20:09 zakim, unmute me 16:20:09 LeoraMorgenstern should no longer be muted 16:21:39 Dave: for the issue of how to extend on top of RDF: in the OWL world, the issue is not a syntax one, it's that OWL was trying to be a semantic extension of RDF --- doing the same sntax semantic extension of RDF caused semantic problems. 16:22:24 DAve: Proposal of RIF is not to do that. It's not that RIf doc would be in rDF; it's simply to use RDF to encode things .. therefore the semantic issues that the OWL community faced would not arise. 16:22:32 Dave: We'd need to be very careful in getting advice from OWL community here, since they have semantic issues (with being an RDF extension) which don't seem to apply to us. 16:24:39 cmsa: (following harold): if we use rdf/xml only as syntax, as a carrier, what's the benefit to the rdf people? 16:24:44 zakim, mute me 16:24:44 LeoraMorgenstern should now be muted 16:25:11 RDF syntax would allow that a rule has 'extra parts', which are just not mentioned here. 16:25:16 dave: as sandro said, we have a well-defined syntax we can just get off the shelf. 16:25:27 dave: second, we can use various tools. 16:26:00 dave: third, it's important that metadata be interpretable as rdf and if you already have your syntactic encoding in rdf, you have that. 16:26:00 s/well-defined/well-defined self-describing/ 16:26:25 ... but RIF syntax should comply to a 'closed-property assumption'. 16:28:02 cmsa: to harold and/or sandro: in proposed serializatoin, for the examples in current draft, would serizalizatoin give different result from proposed syntax in draft? 16:28:12 sandro: yes, for some of hte leaves, liek $49? 16:28:26 sandro: for information already there, it shojuldn't be significantly different. 16:28:43 DaveR, re: metadata, you had shown in your 'Worked example' how to embed a pure XML syntax into RDF. 16:28:50 Harold: sure, if you take a RIF document and add additional RDF assertions then it would either be no longer a legal RIF document or the additions would be treated as metadata 16:29:26 sandro: we can show examples, so people can see this better. 16:29:26 Harold: yes, my original proposal was to avoid the RDF/XML discussion for the build of the condition language but retain it at the top level to permit metadata 16:29:35 s/build/bulk/ 16:30:11 -PaulaP 16:30:44 Leora - sorry I was trying to respond to Harold's IRC discussion .. I can see the abmiguity! 16:31:26 next agendum. 16:31:28 +1 16:31:30 next agendum 16:31:31 +1 adjourn 16:31:34 -IgorMozetic 16:31:35 AOB: None 16:31:35 -johnhall 16:31:36 -Allen_Ginsberg 16:31:38 -Gary_Hallmark 16:31:39 -Harold 16:31:40 zakim, unmute me 16:31:40 LeoraMorgenstern should no longer be muted 16:31:42 -MichaelKifer 16:31:43 -Jeff_Pan 16:31:44 -DavidHirtle 16:31:47 -Mike_Dean 16:31:48 -Dave_Reynolds 16:31:50 JeffP has left #rif 16:32:16 q? 16:32:18 q? 16:32:21 ack dave 16:32:25 zakim, list attendees 16:32:25 As of this point the attendees have been Harold, csma, PaulaP, LeoraMorgenstern, Dave_Reynolds, Sandro, IgorMozetic, Allen_Ginsberg, Jeff_Pan, johnhall, DavidHirtle, Gary_Hallmark, 16:32:28 ...
