15:14:33 <kasei> i went through the function tests several weeks ago and am happy with them. would be nice if someone else could glance over them before we approve them.
15:14:34 <bglimm> for those that are ready

15:15:56 <NickH> AxelPolleres: next item on agenda is checking action and issue status
15:18:04 <AxelPolleres> topic: update semantics
15:18:24 <AxelPolleres>
15:19:22 <NickH> sorry, I am finding it really hard to hear/scribe due to a lot of noise around me
15:20:28 <AxelPolleres>
15:20:42 <NickH> AxelPolleres: one of the main issues is around the DELETE operation
15:21:23 <NickH> AxelPolleres: there a problems around an earlier resolution
15:21:48 <AxelPolleres>
15:22:06 <AxelPolleres> "Blank nodes in DELETE templates act as "wild cards", effectively as variables bound to all RDF terms; the same blank node cannot be used in the WHERE clause and the template, or in multiple BGPs, SteveH, dcharbon2, LeeF abstaining "
15:22:51 <AxelPolleres> DELETE { ?X :knows [] } WHERE {...}
15:22:51 <NickH> AxelPolleres: the idea is that bnodes can act as wildcards
15:23:19 <NickH> AxelPolleres: there has been quite a bit of disccussion about this on email
15:23:30 <NickH> AxelPolleres: wondering if anyone has looked into it?
15:23:36 <NickH> AxelPolleres: or has comments about it?
15:24:08 <NickH> <silence on phone>
15:24:09 <NickH> AxelPolleres: we definately need some feedback about it
15:24:36 <NickH> AxelPolleres: I have two proposals summaries in email:
15:24:50 <NickH> s/summaries/summarised/
15:24:58 <AxelPolleres>
15:25:00 <AxelPolleres> q?
15:25:42 <NickH> AxelPolleres: it looks to me like there are three options to deal with blank nodes in delete queries
15:25:59 <NickH> AxelPolleres: third option would be to override the previous resolution
15:26:40 <NickH> AxelPolleres: option 1: blank nodes in the delete templete would be replaced by variables
15:27:36 <NickH> AxelPolleres: option 2 is to copy the modified template into the body
15:28:35 <bglimm> Does ?X have to be bound in the WHERE clause?
15:29:00 <pgearon> no, it may not be
15:27:36 <NickH> AxelPolleres: option3: overriding the original resolution and treating bnodes and in CONSTRUCT/INSERT (which means they have no effect in DELETE)
15:30:24 <Zakim> +??P3
15:30:33 <NickH> Zakim, ??P3 is me
15:30:33 <Zakim> +NickH; got it
15:31:20 <AxelPolleres> Strawpoll: option 1, 2, or 3?
15:31:20 <NickH> AxelPolleres: straw poll
15:31:32 <pgearon> 3
15:31:35 <NickH> 3
15:31:49 <bglimm> undecided
15:31:49 <kasei> 0
15:31:56 <sandro> undecided
15:31:58 <MattPerry> 0
15:31:59 <cbuilara> 0
15:32:06 <AxelPolleres> 1 or2 (but can live with 3)
15:32:06 <bglimm> I have to think about it first�
15:32:49 <NickH> AxelPolleres: would like people to think about it for next week
15:33:22 <Zakim> -NickH
15:33:27 <AxelPolleres> All, please look at a) update semantics, b) the different options in
15:33:41 <pgearon> Re update semantics: My concern is developing a complex description to enable a feature when it is exactly equivalent to the existing alternatives
15:34:10 <NickH> AxelPolleres: do you have any thoughts about it Alex?
15:34:16 <AxelPolleres> strawpoll doesn't give a clear indication so far.
15:34:19 <NickH> Alex: I will need to think about it more
15:34:44 <bglimm> I sugested the rewording for BGP matching extensions
15:35:07 <AxelPolleres> birte, link?
15:35:07 <bglimm> I'll search for it
15:35:41 <NickH> AxelPolleres: can you take a look at the update semantics emails
15:36:06 <bglimm> Hm, the RIF text was already changed
15:36:14 <bglimm> with infinite answers
15:36:35 <bglimm> yes, it is should now
15:36:46 <bglimm> but the text is not in line with the rest of the spec
15:36:57 <bglimm>
15:36:57 <AxelPolleres> it is on the to_last_call page
15:37:06 <bglimm> that's the suggestion for rewording
15:37:21 <AxelPolleres> it is not yet implemented, you mean?
15:37:31 <bglimm> it uses "answer set" instead of solution sequence etc
15:37:44 <AxelPolleres> AOB?
15:37:52 <bglimm> "pattern instance mapping" means "slotion mapping" etc
15:38:09 <bglimm> Ok
15:38:22 <Zakim> -Sandro
15:38:23 <AxelPolleres> adjourned.
15:38:24 <MattPerry> bye
15:38:24 <bglimm> I can also try and dial in without my headset, so I can talk
