- constraints it imposes.]]
- 14:18:20 [kendallclark]
- (hmm, i thought the point was just that, since turtle is commutative, that's a pressure to make, say, optional commutative...or put the other way: inasmuch as we try to make optional order *dependent*, there's a clash with turtle)
- 14:19:27 [LeeF]
- I think I'm still a fan of requiring the first argument to OPTIONAL to be a GroupGraphPattern (as Fred? suggested very recently) - I asked about that a while back (why it wasn't that way) and don't remember the answer I got -- curious what objections are to that
- 14:19:36 [SimonR]
- (I think that's "associative" rather than "commutative".)
- 14:19:37 [LeeF]
- other than it breaking a fair amount of existing SPARQL queries
- 14:20:41 [AndyS]
- If we go for OPTIONAL = left join operator, then its like OPTIONAL applies to everything to the left.
- 14:22:43 [kendallclark]
- (fwiw, i put v. little stock personally in backward compat. at this stage.)
- 14:22:54 [SimonR]
- I still have a bit of an issue with the `unbound' fields that OPTIONAL introduces. They're more like `overbound' AFAICT. Very different from the other unbounds we generate by the other ops.
- 14:23:09 [AndyS]
- The "everything to the left" scoping works quite nicely for both forms of evaluation as well. The app can put {} in for the unusual cases (if there are any)
- 14:24:58 [AndyS]
- SimonR: it's like "missing info" vs "not needed info" NULLs
- 14:25:10 [LeeF]
- i'mn not sure I understand "everything to the left"
- 14:25:31 [LeeF]
- does that mean that:
- 14:25:31 [LeeF]
- { { A } UNION { B } . C OPTIONAL { D } . E }
- 14:25:44 [LeeF]
- the first argument to OPTIONAL is a Group containing the UNION and containing C?
- 14:25:49 [LeeF]
- a group that isn't marked explicitly in the syntax?
- 14:26:22 [SimonR]
- AndyS: In a way, yeah. But it's a bit more of an algebraic issue rather than a matter of just human interpretation in this case.
- 14:26:30 [AndyS]
- Yes - that parsing. It's equiv (I think) to having LeftJoin and Join in groups.
- 14:26:45 [LeeF]
- Not a big fan of implicit groups
- 14:26:59 [AndyS]
- SimonR: we still have 4 more nulls to go! (Codd's 6 kinds)
- 14:27:51 [kendallclark]
- heh, doing lots of integration work for nasa these days... there are 6 kinds of nulls, conceptually, but dozens and dozens of ways of spelling them! :(
- 14:28:12 [SimonR]
- We could go back to CODASYL and have 14 to choose from, IIRC. :)
- 14:28:25 [kendallclark]
- simon: you ready to scribe?
- 14:28:35 [AndyS]
- May there are more than 6 kinds - just add an extra quark to the mix and hey presto - more kinds of particles
- 14:28:36 [SimonR]
- As really as I'm going to get.
- 14:28:50 [SimonR]

- agendum 3. "Can We Go Home^H^H^H^H^H to Last Call Again?" taken up [from kendallclark]
- 14:43:01 [LeeF]
- ACTION: LeeF and EliasT to summarize open SPARQL protocol issues and propose resolutions in email to WG
- 14:44:38 [SimonR]
- Chair warns that he may not be able participate in DAWG in 2007; should consider who will be next chair, and try to get as much done before transition.
- 14:46:43 [SimonR]
- FredZ: Doesn't see much advance in strengthening the formal semantics; primary barrier to going to LC
- 14:47:46 [kendallclark]
- +1 from UMD on that point
- 14:48:17 [kendallclark]
- Fred: push formal semantics into separate section of doc, not distributed thru'out

- (Kendall just covered my issue)
- 14:52:08 [LeeF]
- q+ to express reservations about the time-cost of reworking the current document in a large manner
- 14:52:16 [SimonR]
- Kendall notes that the idea of a separate formal semantics document has be explored previously and decided against.
- 14:52:54 [SimonR]
- FredZ isn't suggesting a second document, just an appendix or the like where the formal definition is collected.
- 14:53:16 [AndyS]
- The editors didn't think parallel work woudl help - not that they were against a separate doc - the docs need to be linked and other groups have found this to be a serious problem
- 14:53:18 [patH]
- seems like there are issues f presentation and those of actual content. I suggest first can be left aside for now until we get the secnod sorted out. Maybe separate temporary document is a good strategy for getting the latter sorted out.
- 14:53:31 [patH]
- q-
- 14:54:10 [LeeF]
- +1 to patH -- second document (perhaps starting from one of Fred's papers analyzing the semantics) as a way to get the semantic content sorted out sounds like a good idea to me
- 14:54:47 [kendallclark]
- or starting w/ the chilean's semantics doc, which is rumored to be (1) nearly complete and (2) almost ready for circulation
- 14:55:10 [LeeF]
- I'd be fine with that, also, though I'm not sure how complete it is.
- 14:55:38 [AndyS]
- Chilean doc applies to lean graphs so we still have work there
- 14:55:48 [kendallclark]
- well, no one is, since they aren't circulating it yet
- 14:56:09 [kendallclark]
- there's *another* chilean doc, andy
- 14:56:20 [kendallclark]
- i'm not talking about the one they've circulated
- 14:56:34 [patH]
- Lean graphs is an easy case.
- 14:56:35 [kendallclark]
- (and, yes, referring to non-public docs is bullshit. Sorry. :>)
- 14:56:43 [LeeF]
- Ah, I didn't know there was another doc.

- 14:56:58 [kendallclark]
- ack AndyS
- 14:57:30 [patH]
- Ive got an alternative suggestion for treating the basic semantics conditons as a necessary but not sufficeint constraint. THis is 'weak' but relatively uncontroversial and undercommitted. Manchester will be unhappy but not in open revolt.
- 14:57:32 [SimonR]
- FredZ: Analysis of queries requires global info, which is why distributing the formal definitions makes thing difficult.
- 14:58:56 [kendallclark]

- LeeF, you wanted to express reservations about the time-cost of reworking the current document in a large manner

- q+ to talk about "alogorithm"
- 15:00:26 [SimonR]
- LeeF: FredZ has valid concerns, but also need to consider getting things done in a timely fashion.
- 15:00:28 [AndyS]
- q-
- 15:02:47 [SimonR]
- Kendall: Doesn't see that the changes proposed are likely to actually be incorporated in the document. Semantics is the "900lb gorilla", which means that closing smaller issues is helpful without really getting us finished
- 15:02:54 [ericP]
- q?
- 15:03:52 [AndyS]
- +1 to more test cases - and it's a WG output
- 15:04:24 [AndyS]
- Operational semantics for the algebra are doable. It's entailment that is open.
- 15:05:10 [SimonR]
- PatH: Semantics is ambiguous -- model-theoretic (Enrico) vs algebraic (Fred).
- 15:05:14 [AndyS]
- just change to bottom-up evaluation (carefully!) and OPTIONAL == LeftJoin
- 15:06:54 [AndyS]
- q+
- 15:07:14 [SimonR]
- Kendall: Does entailment matter, given the current group membership?

- 15:08:09 [AndyS]
- It matters to HP that we have a proper review in LC and CR and be responsive to comments.
- 15:08:20 [kendallclark]
- ack AndyS
- 15:08:29 [SimonR]
- FredZ: Working on a paper to show that adopting mapping won't preclude entailment
- 15:08:59 [ericP]
- q+ to mention charter
- 15:09:50 [patH]
- +1 to doing very most minimal thing that will work. BUt not ignore totally. I think we are in violent agreement.
- 15:09:53 [kendallclark]
- ack ericp
- 15:09:53 [Zakim]
- ericP, you wanted to mention charter
- 15:10:03 [jeen]
- ...what pat said
- 15:10:30 [SimonR]
- EricP: Mapping would minimally satisfy the charter.

- q?
- 15:13:12 [patH]
- pat will draft replacement vanilla entailment section.
- 15:13:38 [kendallclark]
- ACTION PatH: to draft replacement vanilla entailment section for WG consideration
- 15:14:35 [SimonR]
- Kendall: Encourages removal of things from the language.
- 15:15:11 [SimonR]
- (Particularly OPTIONAL)
- 15:15:27 [LeeF]
- I need to check with some other folks, but I believe my organization would object to dropping OPTIONAL.
- 15:15:46 [SimonR]
- q+
- 15:17:43 [LeeF]
- +10million to Simon
- 15:18:29 [patH]
- suggest that Kendalls general point is well taken, but we don't drop optional *today*.
- 15:18:51 [SimonR]
- SimonR: OPTIONAL is a bad solution, but the problem it solves is a vital one -- even a bad solution is better than no solution
- 15:19:19 [patH]
- SimonR, any suggestion for an alternative way of doing the practical job?
- 15:19:49 [kendallclark]
- zakim, take up next agendum
- 15:19:49 [Zakim]
- agendum 4. "Grammar Changes" taken up [from kendallclark]
- 15:20:01 [SimonR]
- EricP: Urges keeping plugging away on test cases. Definitely gets closer to LC
- 15:20:08 [kendallclark]
- http://lists.w3.org/Archives/Public/public-rdf-dawg/2006OctDec/0055.html
- 15:20:41 [SimonR]
- q-
- 15:23:47 [SimonR]
- AndyS: Grammar changes (0055) -- LIMIT/OFFSET, OPTIONAL, FILTERS as part of groups (no bnodes in FILTERs)
- 15:27:03 [SimonR]
- AndyS: (cont'd) /u escape processing removed to a separate preprocessing phase; bugfixes for bnode GRAPH, brackets around function calls, lowercase token rule name should've been uppercase. The only language change is the bnode/FILTER one
- 15:29:11 [LeeF]
- For the record, in the email referenced above I think it would be correct to s/NCNAME1p/NCCHAR1p (very very very minor point)
- 15:32:13 [SimonR]
- Chair requests a decision on grammar change #3 (bnode/FILTER)
- 15:32:38 [LeeF]
- Is it #56 PrimaryExpression ?
- 15:32:54 [LeeF]
- I think it is.

- -jeen
- 15:33:00 [LeeF]
- BlankNode was removed from #56 PrimaryExpression
- 15:33:02 [SimonR]

- EricP: Suggests approving the first 6; issue raised by others about how to test extended implementations.
- 15:43:58 [AndyS]
- +1
- 15:46:47 [ericP]
- PROPOSED: approve open-eq-0{1,2,3,4,5,6}
- 15:47:13 [SimonR]
- PROPOSED to approve the open world value testing test cases open-eq-01 to open-eq-06 (0071.html)
- 15:47:24 [SimonR]
- APPROVED
- 15:50:42 [SimonR]
- Scope of FILTERS issue discussion picked up.
- 15:50:58 [fred]
- { ?x ?y ?z OPTIONAL {....} FILTER (...) OPTIONAL {...}}
- 15:51:14 [fred]
- in preceding example, does the FILTER interrupt the two OPTIONALs
- 15:51:22 [LeeF]
- Fred, I think that's a different issue
- 15:51:24 [fred]
- so that the second one's first argument is an empty pattern
- 15:51:59 [kendallclark]
- kendallclark has joined #dawg
- 15:52:06 [kendallclark]
- (stupid network)
- 15:52:09 [AndyS]
- If the optional applies to the all to the left, it works out.
- 15:52:12 [ericP]
- .PROPOSED: the scope of a FILTER comes from the nearest enclosing {}s and the scopes inherit from outer {}s
- 15:52:38 [AndyS]
- 10 01{ ?x ?y ?z OPTIONAL {....} FILTER (...) OPTIONAL {...}}
- 15:53:19 [kendallclark]
- +1 to andy's point
- 15:53:37 [AndyS]
- 10 01{ { ?x ?y ?z OPTIONAL {....} FILTER (...) } OPTIONAL {...}}
- 15:54:14 [kendallclark]
- for some reason I can't see what Andy's just typed :)
- 15:54:18 [kendallclark]
- no matter
- 15:54:19 [ericP]
- ditto
- 15:54:31 [LeeF]
- Reiterates reservations about implicit curly brackets!
- 15:54:43 [patH]
- { ?x ?y ?z OPTIONAL {....} FILTER (...) OPTIONAL {...}}
- 15:54:56 [fred]
- I agree with Lee, I think explicit braces for first arg of OPTIONAL would be good
- 15:55:27 [AndyS]
- Lee means? 10 01{ ?x ?y ?z OPTIONAL {....} OPTIONAL {...} FILTER (...)}
- 15:55:46 [ericP]
- 2006-10-17T15:52:38Z <AndyS> { ?x ?y ?z OPTIONAL {....} FILTER (...) OPTIONAL {...}}
- 15:55:47 [SimonR]
- Foo- { { ?x ?y ?z} OPTIONAL {....} FILTER (...) OPTIONAL {...}}
- 15:55:49 [ericP]
- 2006-10-17T15:53:37Z <AndyS> { { ?x ?y ?z OPTIONAL {....} FILTER (...) } OPTIONAL {...}}
- 15:56:06 [ericP]
- huh, was just invisible, but it was available for paste
- 15:58:37 [kendallclark]
- Leef: will you write in IRC an example of what you want? I still haven't seen it clearly ;)
- 15:58:48 [LeeF]
- I want *this* to be illegal:
- 15:59:00 [LeeF]
- { :a :b :c OPTIONAL { :d :e :f } }
- 15:59:02 [LeeF]
- in favor ot
- 15:59:11 [LeeF]
- { { :a :b :c } OPTIONAL { :d :e :f } }
- 15:59:22 [patH]
- Im confused, myself.
- 15:59:56 [AndyS]
- { {} OPTIONAL {} UNION {} } since has precedence to consider
- 15:59:56 [SimonR]
- PROPOSED to extend for 5 mintes
- 16:00:18 [LeeF]
- yes, definitely precedence to consider, but i'd be hoping that it would be easy to nail down :)
- 16:02:24 [fred]
- I think mandatory braces means no need for precedence
- 16:02:52 [LeeF]
- fred, we'd need associativity specified, right?
- 16:03:21 [AndyS]
- See 04 01{ {} OPTIONAL {} UNION {} }
- 16:03:23 [fred]
- not if OPTIONAL is only binary operator
- 16:03:29 [fred]
- note that UNION is n-ary
- 16:03:36 [patH]
- Good point, fred.
