14:04:21 <AxelPolleres> ... we sketched out some examples on update on graphstore.
14:04:28 <AxelPolleres> ... up to editors now to implement
14:04:42 <LeeF> LeeF: update call - consensus on definition of graph store state, operations as functions from graph store state to graph store state

14:05:51 <LeeF> AxelPolleres: two unaddressed comments

14:09:27 <AndyS> First link is wrong?
14:10:31 <LeeF> AxelPolleres: where do we want to add the entailment regime? 
14:10:39 <LeeF> ... then we need a URI for the graph
14:10:59 <AxelPolleres> sd:entailmentRegime 
14:11:05 <LeeF> ... if we use the SD entailment regime property then what is the subject of that?
14:11:24 <LeeF> ... if the graph itself then in one manifest file we would fix the entailment regime for a graph for all tests
14:11:30 <AndyS> zakim, who is on the phone?
14:11:30 <Zakim> On the phone I see AndyS, AxelPolleres, kasei (muted), Lee_Feigenbaum, bglimm (muted), MattPerry, pgearon

14:14:30 <bglimm> But mine didn't allow for using different ent. regimes for different graphs
14:14:33 <LeeF> qt:data <foo.ttl> ; qt:entailmentSetup [ qt:graph <foo.ttl> ; qt:regime ent:RDFS ]
14:14:47 <AndyS> what about:    [ qt:data <g> ; sd:entailmentRegime (<g> ent:RDF) ]
14:15:37 <LeeF> AndyS: what Lee and I are trying to get to is to talk about the data and then annotate it with the entailment info that should also apply
14:17:03 <LeeF> AndyS: We could go with Birte's setup where you have one entailment regime tested per query
14:17:44 <AndyS> qt:worksOn [ qt:data <g> ; sd:entailmentRegime ent:RDFS ] 
14:18:50 <SteveH> SteveH has joined #sparql
14:19:08 <Souri> +1 to simple proposal => one entailment regime for the query
14:19:28 <bglimm> that would work for me
14:19:30 <bglimm> yes

14:19:42 <AndyS> ... but simple is good.
14:20:16 <LeeF> AxelPolleres: go with simple for now
14:20:32 <Zakim> +Garlik
14:20:40 <SteveH> Zakim, Garlik is temporarily me
14:20:40 <Zakim> +SteveH; got it
14:20:42 <AxelPolleres> let's go with the simple proposal from Birte for now, for more complex ones I will try to capture Lee's proposal for more complex ones.
14:21:31 <LeeF> AxelPolleres: we need the ability to refer to different graphs with the same name to describe the state of the graph store before and after an update
14:22:26 <LeeF> AndyS: who's implemented these test cases?
14:22:30 <LeeF> (silence)
14:22:37 <LeeF> AndyS: getting to update soon, entailment later on
14:23:17 <bglimm> I hope to soon start with entailment tests

14:36:23 <AxelPolleres> How does basic federated query interact with SPARQL/Update?
14:36:38 <pgearon> that's an issue that mostly bothers SteveH. IIRC
14:36:53 <SteveH> sounds right
14:37:10 <AndyS> Last week: http://www.w3.org/2009/sparql/track/issues/18
14:37:49 <LeeF> AxelPolleres: do we need to say anything about the interaction of federated query with SPARQL Update?

14:38:57 <AxelPolleres> q?

14:39:45 <LeeF> pgearon: I don't think it's a big issue but worth mentioning in the udpate document

14:41:01 <SteveH> +1
14:41:01 <AndyS> If update requests are truly atomic, it's a bit of a non-effect (atomic being a somewhat of an ideal)

14:41:19 <AndyS> +1
14:41:21 <SteveH> AndyS, not really, as the SERVICE request will happen inside a different context

15:00:21 <kasei> AndyS, question about PP doc...?
15:00:44 <AxelPolleres> rrsagent, make records public
15:01:51 <AndyS> kasei, need to be a quick Q 
15:01:55 <AxelPolleres> summary: closed many issues, will continue at ISSUE-48 next time
15:02:07 <AxelPolleres> member:rrsagent, make records public
15:02:07 <kasei> I see "A path of length zero connects a graph node to itself," but also in Defn of ZeroLengthPath "also any IRIs explicitly given as endpoints".
15:02:18 <kasei> graph node? or IRI? (what about literals?)
15:02:21 <AxelPolleres> rrsagent, make records public
15:02:31 <AndyS> IRI is wrong - "RDF term" 
15:02:43 <kasei> ok, great. thanks.
15:02:43 <AndyS> we do blank nodes as well :-)

15:02:51 <Zakim> SW_(SPARQL)10:00AM has ended
15:02:53 <Zakim> Attendees were AndyS, AxelPolleres, kasei, Lee_Feigenbaum, bglimm, MattPerry, pgearon, Souri, SteveH, chimezie
15:03:02 <AxelPolleres> thanks lee for scribing!
15:03:03 <kasei> yeah, but they can't be named explicitly...
15:03:15 <AndyS> and the algorithm description for "arb path" is to be ignored - reworking it currently.
15:03:20 <kasei> they're taken care of by "matches subjects and all objects"
15:03:47 <kasei> ah, ok. i was about half way through working it out
15:04:13 <AndyS> "explicitly" given can arise from a path expansion.
