16:13:17 [cygri]
guus: is his response on the mailing list?
16:13:22 [MacTed]
16:13:33 [cygri]
ericP: it's on the www-international list
16:14:41 [cygri]
... issue-180, i fixed this everywhere except in the grammar, where we follow XML grammar convention. he was content with that.
16:15:32 [cygri]
... issue-183, we need good examples for integer, decimal and double
16:15:38 [cygri]
... for the shortcut notations

... i came up with a chemistry example. he liked it. it might be a bit harder to approach. i can commit if the WG is ok with it
16:16:52 [PatH]
I like it, especially if it said in a squeaky voice.
16:17:13 [cygri]

16:18:36 [cygri]
... issue-189 was effectively the same as issue-178
16:19:12 [cygri]
... issue-190 requires no action on our part, he agreed that staying aligned with XML is a reasonable choice
16:19:16 [cygri]
... that's all
16:19:33 [cygri]
guus: very good, that's not as bad as i thought
16:19:35 [PatH]
Well done Eric.
16:20:02 [cygri]
... it would be good if this was on record on our comments list
16:20:09 [cygri]
ericP: i'll try to bounce it there
16:20:43 [cygri]
subtopic: Left-recursive LALR(1) grammar for turtle
16:21:05 [cygri]
ericP: it would be very nice to publish with an LALR or LL1 grammar
16:21:17 [cygri]
... andy said that sandro's grammar has a shift-reduce conflict
16:21:34 [AndyS]
16:21:36 [cygri]
... including those is unfortunate as it's bad for error reporting
16:21:45 [cygri]
... but we need to make progress
16:22:12 [cygri]
... propose adding a note that shows both productions
16:22:13 [AndyS]
The S/R error is silent in many systems (default is shift - see Bison reference)
16:22:38 [cygri]
... mark it as an at-risk feature in the next publication
16:22:40 [ivan]
16:22:43 [Guus_]
16:22:59 [cygri]
ivan: you think we can't go to CR?
16:23:07 [ericP]
16:23:18 [cygri]
ericP: if we changed the language -- changed what's an acceptable turtle document...
16:23:20 [Arnaud]
didn't we go over this last week already??
16:23:32 [cygri]
ivan: if you mark the specific feature at-risk, then i don't see a problem
16:23:50 [cygri]
guus: we discussed this extensively last week
16:24:17 [AndyS]
q+ to ask why we replace one rule with one which creates probs for other people.
16:24:19 [cygri]
ericP: i just would like to make sure that the at-risk text mentions that we plan to find a grammar that's LALR1 and LL1 friendly
16:24:30 [ivan]
ack ivan
16:24:52 [PatH]
Aew we going to do that or are we inviting the world to ty to write one?
16:25:37 [PatH]
16:26:27 [ericP]
PROPOSED: provide At Risk text which notes: 1 change from prior publication; 2 that the WG wants "<><><>;;;." to be legal; 3 that we will look for a grammar representation which produces no S/R conflicts in LL(1) or LALR(1)
16:26:49 [cygri]
ericP: this should be possible, as SPARQL grammar doesn't have conflicts
16:27:53 [cygri]
AndyS: i thought the agreement was to keep the grammar from sparql, and add a note saying how it can be done with a different grammar
16:28:14 [cygri]
ericP: I believe that's a change from the previous publication
16:28:51 [cygri]
AndyS: we shouldn't be making life more difficult for some people just to make it easier for some others.
16:29:11 [cygri]
ericP: what's wrong with finding a grammar that works for both?
16:29:43 [cygri]
[scribe can't keep up]
16:30:05 [Guus_]
let's summarize later, richard
16:30:29 [AndyS]
SPARQL -- [77] PropertyListNotEmpty ::= Verb ObjectList ( ';' ( Verb ObjectList )? )*
16:30:42 [cygri]
ericP: i think we could make a grammar that is LL1 and LALR1 friendly. but that would take too much time.
16:31:18 [cygri]
AndyS: we would then have different grammars for turtle and sparql
16:32:04 [cygri]
ericP: what's the concern with finding a LALR1 friendly expression?
16:34:35 [AndyS]
16:34:56 [cygri]
ericP: the SPARQL grammar has no shift-reduce conflict, but the same grammar rules produce a shift-reduce conflict in turtle because the context is different
16:36:33 [cygri]
[disagreement whether the current grammar produces a S/R conflict or not]
16:37:35 [PatH]
Hey, the Pope just tweeted.
16:38:02 [LeeF]
16:38:10 [AndyS]
I do not support the text but will not object.
16:38:19 [Arnaud]

16:38:47 [PatH]
16:38:51 [MacTed]
16:38:57 [Souri]
16:39:12 [yvesr]
16:39:46 [cygri]
ivan: having an at-risk on a minor detail like that is the way to go, shouldn't hold up CR
16:39:56 [LeeF]
16:40:07 [cygri]
ericP: but the question is whether it should also say that we may still tweak the grammar
16:40:11 [AndyS]
Alternative proposal --
16:40:35 [cygri]
RESOLUTION: provide At Risk text which notes: 1 change from prior publication; 2 that the WG wants "<><><>;;;." to be legal; 3 that we will look for a grammar representation which produces no S/R conflicts in LL(1) or LALR(1)
16:40:53 [cygri]
AndyS: alternative proposal is for the record
16:41:28 [cygri]
guus: ivan, would it be okay to make CR proposal given that it was not on the agenda?
16:41:31 [cygri]
ivan: yes

Created ACTION-218 - Write Turtle CR transtion request [on Guus Schreiber - due 2012-12-19].
16:47:17 [cygri]
... i will write the transition request, may need some input from the eds
16:47:34 [cygri]
ivan: target publication date would be 1st or 2nd week of january
16:48:07 [cygri]
... there has to be one week between the request for transition and the transition itself
16:48:47 [cygri]
... the final version has to be frozen and goes to the transition call
16:48:58 [cygri]
... when can you cast it in concrete?
16:49:07 [cygri]
ericP: tomorrow, today, when is it needed?
16:49:28 [cygri]
guus: i would like to have a frozen version as quick as we can
16:50:01 [cygri]
ivan: we need five business day between transition request and transition call
16:50:15 [cygri]
guus: can we have the call end of next week?
16:50:37 [cygri]
ivan: we could try next week friday if the request goes out tomorrow
16:51:11 [cygri]
... assuming ralph is around
16:51:45 [cygri]
guus: so if the request goes out next week, we can have the call first business week of january
16:52:54 [cygri]
