14:16:41 <AxelPolleres> strbefore02 and strafter02 are new."

14:33:14 <AxelPolleres>
14:33:22 <AxelPolleres> no changes since last call...
14:33:26 <pgearon> bglimm: no reviewers assigned, but no changes since last call
14:33:54 <pgearon> bglimm: no acknowledgment from Michael Schneider
14:34:06 <pgearon> AxelPolleres: ping Michael, but should be OK otherwise
14:34:37 <chimezie> Zakim, unmute me
14:34:37 <Zakim> Chimezie should no longer be muted
14:34:50 <pgearon> bglimm: Michael Schneider wants to implement all, Talis to do some, Jeff Pan to do some....
14:35:19 <pgearon> sandro: should we tell them our deadline? Or ask them what their timeframe is?
14:35:29 <pgearon> bglimm: maybe was can ask them
14:35:57 <pgearon> sandro: we should let them know our timeframe is short
14:36:27 <pgearon> AxelPolleres: we need some response, because this is the area where we have the least idea of what's going on
14:36:52 <pgearon> bglimm: chimezie and I are the ones in the group doing this work
14:37:08 <AxelPolleres> ACTION: birte to reach out to Entailment implementers about status/schedule of their implementations, tell them that we plan within a month
14:37:08 <trackbot> Created ACTION-637 - Reach out to Entailment implementers about status/schedule of their implementations, tell them that we plan within a month [on Birte Glimm - due 2012-06-12].
14:37:12 <pgearon> bglimm: I don't have time for implementing right now
14:37:22 <bglimm> Zakim, mute me
14:37:22 <Zakim> bglimm should now be muted
14:37:30 <pgearon> AxelPolleres: let implementors know that we need something within a month, if they're going to do it
14:37:32 <bglimm> Zakim, unmute me
14:37:32 <Zakim> bglimm should no longer be muted
14:37:54 <pgearon> AxelPolleres: only have template on PR page, so adding comment would be good
14:37:55 <bglimm> Zakim, mute me
14:37:55 <Zakim> bglimm should now be muted
14:38:02 <pgearon> bglimm: will do that now
14:38:04 <AxelPolleres> subtopic: federated query
14:38:18 <pgearon> cbuilara: only one comment last week
14:38:43 <pgearon> cbuilara: 2 tests. Tried to finish everything for To_PR
14:39:04 <AxelPolleres>
14:39:51 <pgearon> cbuilara: only change was on BINDINGS changed to VALUES
14:40:11 <chimezie> Zakim, mute me
14:40:11 <Zakim> Chimezie should now be muted
14:40:25 <pgearon> subtopic: results formats
14:40:53 <AxelPolleres> nothing new
14:40:57 <AxelPolleres> topic: comments
14:40:59 <pgearon> AxelPolleres: unless someone has more on To_PR page we can move to something new
14:41:21 <pgearon> AxelPolleres: on comments list. Comment by TBL?
14:41:35 <pgearon> AxelPolleres: not sure if we're expected to react and how
14:41:42 <AxelPolleres>
14:42:22 <sandro> sandro: I read that as being primarily to the RDF WG.
14:42:24 <pgearon> sandro: this is really for the RDF WG, since it's about Turtle comments. It's relevant to us, but the RDF WG is the lead
14:42:56 <pgearon> sandro: we can formally say that we're not planning on adding multi-line comments
14:43:38 <pgearon> sandro: TBL was responding to someone else asking for these comments, so this would not be refuting TBL
14:43:58 <pgearon> AxelPolleres: will you send this quick response please
14:44:56 <AxelPolleres>
14:45:10 <AxelPolleres>
14:46:34 <pgearon> kasei: SD offers a way to say that you dereference URLs
14:47:02 <pgearon> AxelPolleres: send an email explaining, and say that this is an informal response, do you require a formal one?
14:47:09 <AxelPolleres> ACTION: greg to informally reply on pointing to SD and asking whether formal response is needed.
14:47:09 <trackbot> Created ACTION-638 - Informally reply on pointing to SD and asking whether formal response is needed. [on Gregory Williams - due 2012-06-12].
14:49:38 <AxelPolleres> topic: interplay of aggregates
14:49:38 <AxelPolleres>
14:50:21 <pgearon> pgearon: q to kasei - is there a way to use SD to describe only dereferencing a URL if there is no existing graph with that name? This is Mulgara's behavior
14:50:58 <pgearon> kasei: not really. This sounds like dereferencing, but with more specificity. Looking to see how the community uses these descriptions to see which direction to take it in future
14:51:02 <AxelPolleres> SELECT  AVG(?x * MAX (?y) )
14:51:19 <AxelPolleres> SELECT (max(?x) As ?M) (avg(?M+1) AS ?A)
14:51:28 <pgearon> AxelPolleres: question was if this should be allowed or not
14:51:43 <pgearon> +q
14:52:02 <AxelPolleres> ack pgearon
14:52:14 <pgearon> AxelPolleres: want quick opinions today
14:52:51 <AxelPolleres> paul: andy reported that disallowing would be ok, as subqueries allow it 
14:53:11 <pgearon> AxelPolleres: does anyone want to allow this?
14:53:23 <kasei> it should be disallowed.
14:53:27 <bglimm> I think it makes the algebra unnecessarily complicated
14:53:31 <pgearon> AxelPolleres: is there consensus to disallow?
14:53:39 <bglimm> +1 to disallow
14:53:44 <pgearon> +1 to disallow
14:53:52 <chimezie> +0 not sufficiently swapped in to conversation
14:53:55 <AxelPolleres> strawpoll: Disallow nested aggregates (given the understanding that it can be done in subwqueries if needed)
14:53:57 <Olivier> 0
14:54:01 <cbuilara> 0
14:54:09 <AxelPolleres> +1
14:54:10 <kasei> +1 to disallow
14:54:20 <pgearon> I think it makes algebra more complicated without benefit. No legitimate use cases were presented in the conversation
14:55:05 <AxelPolleres> olivier: no strong position, no objection either
14:55:27 <pgearon> Also, it was pointed out that subqueries make it clearer what is being requested. Sub-aggregates in the select clause are much less clear
14:55:47 <AxelPolleres> I tend to agree on that point, paul.
14:55:47 <pgearon> AxelPolleres: any other business?
14:55:50 <AxelPolleres> AOB?
14:56:00 <AxelPolleres> adjourned
