If there's a published dataset, ... something ... default graph URI. 14:14:21 <sandro> kasei: The protocol has ways you can rename graphs to be the defautl graph for matching 14:14:26 <sandro> AndyS: That stuff should work. 14:14:50 <sandro> kasei: I'll send you details and lets sort this out 14:14:54 <sandro> AndyS: okay. 14:15:23 <chimezie> Zakim, unmute me 14:15:23 <Zakim> chimezie should no longer be muted 14:15:32 <AxelPolleres> topic: update implementations 14:15:40 <sandro> axel: Entailment Regimes? 14:15:46 <sandro> chimezie: I don't have an update on that 14:15:47 <AxelPolleres> s/update/entailment/ 14:16:42 <AxelPolleres> sandro: mentioned this in SWCG meeting last week... Ian horrocks offered to ping potential implementers for DL regimes. 14:16:59 <AxelPolleres> we should ping thre RIF mailinglist... 14:17:06 <sandro> action: sandro ping RIF folks on ER 14:17:06 <trackbot> Created ACTION-669 - Ping RIF folks on ER [on Sandro Hawke - due 2012-08-21]. 14:17:17 <AxelPolleres> ACTION: sandro to ping RIF WG mailinglist on SPARQL/RIF implementations. 14:17:17 <trackbot> Created ACTION-670 - Ping RIF WG mailinglist on SPARQL/RIF implementations.

Sandro wanted to look into that.... 14:19:40 <sandro> axel: Old one from Jeremy Carroll, re graph protocol, URI to IRI 14:19:48 <chimezie> Zakim, unmute me 14:19:48 <Zakim> chimezie should no longer be muted 14:19:50 <sandro> axel: Paragraph gone, outdated. 14:19:59 <sandro> chimezie: I just need to ping Jeremy 14:20:24 <sandro> axel: kk-13 14:20:46 <sandro> axel: I think it's ready to send. 14:20:52 <sandro> chimezie: sent and ack'd. 14:20:59 <sandro> chimezie: I just updated the wiki now. 14:21:35 <chimezie> Zakim, mute me 14:21:35 <Zakim> chimezie should now be muted 14:21:52 <sandro> axel: Long response draft to Dave Becket, outdated, short one should do. I'll ping Steve 14:22:34 <sandro> andy: that one is sent 14:22:37 <sandro> axel: Ah right. 14:23:33 <sandro> axel: Comments on PP's from Nick Humphrey 14:24:02 <sandro> axel: Inform reply from Andy, er, Steve, saying this can be done with Aggregrate. 14:24:15 <sandro> andy: Expept it says not a formal response. :-) 14:24:32 <sandro> axel: I'll ping Nick on formal response status. 14:24:57 <AxelPolleres> ACTION: axel to ping Nick on whether NH-5 needs a formal response 14:24:57 <trackbot> Created ACTION-671 - Ping Nick on whether NH-5 needs a formal response [on Axel Polleres - due 2012-08-21]. 14:25:00 <sandro> AndyS: He's just looking at PP syntax, not having read some bits elsewhere in the spec. 14:25:19 <sandro> AndyS: I'll do NH-4 14:26:13 <sandro> axel: Some comments on client semantics. Maybe reply to them together 14:26:46 <AxelPolleres> BIND in combination with other graph patterns... 14:26:47 <sandro> andy: I looked. They only consider part of the problem space. Their case always has bind next to something else, not a BGP. This needs some thought. 14:27:13 <AxelPolleres> looks like these queries need a subselect. 14:27:19 <sandro> andy: Perhaps a different form of query, using a subselect, would help. 14:27:44 <sandro> axel: Do we need to change something? 14:28:39 <sandro> andy: Holger's point could maybe be seen one way, Jeremy's made things a little more contrained. 14:31:20 <AxelPolleres> http://lists.w3.org/Archives/Public/public-rdf-dawg-comments/2012Aug/0011.html 14:31:39 <sandro> axel: implies std behavior of default graph, which isnt how it works, I think 14:32:15 <sandro> axel: I'll try to find out what he wants 14:32:27 <sandro> andy: lets consider it as a couple of different parts 14:33:11 <sandro> andy: First part usual approach would be not using the word graph. FROM DEFAULT, FROM <...> . In the past we've said if you want that, put your dg in with a name, too. 14:33:52 <sandro> andy: It's not a perfect solution, true 14:34:23 <sandro> andy: If you're using multipl FROMs you're asking for a kind of merge. You can use GRAPH for that, although it's not pretty. 14:34:50 <AxelPolleres> you can use GRAPH for that, all above that would be Composite_Dataset (cf. posponed features)? 14:35:14 <sandro> AndyS: Greg, does your system offer a choice about what the dg is? 14:35:29 <sandro> kasei: No, I've never offered a union default 14:35:47 <sandro> AndyS: Last thing - year Compisite_Dataset feature. I don't think it's trivial. # SPECIAL MARKER FOR CHATSYNC. DO NOT EDIT THIS LINE OR BELOW. SRCLINESUSED=00000140
