- 14:06:20 [ivan]
- next tuesday, this time
- 14:06:32 [ivan]
- regrets: orri, ivan
- 14:06:40 [ivan]
- s/ivan/ivan-the-older/
- 14:06:55 [ivan]
- lee: any report of our liaisons?
- 14:07:14 [ivan]
- AndyS: i believe sparql and owl will ask us to review rdf:text
- 14:07:28 [AndyS]
- s/sparql/rif/
- 14:07:38 [ivan]
- LeeF: what we said that when the text is ready we will send it to the mailing list and see if anybody is interested
- 14:07:47 [ivan]
- Topic: rechartering issue
- 14:08:47 [ivan]
- lee: my understanding is that it should not affect our work at all
- 14:09:14 [ivan]
- ... this may be naive or optimistic, but we should be able to do the same work the same way
- 14:10:24 [LeeF]
- ivan: the way the charter is done today is extremely open-ended, and companies that really want to consider all their patent issues cannot make any patent disclosures right now since nothing specifies what will be part of a Recommendation
- 14:10:40 [LeeF]
- ... we received remarks from members making us consider this
- 14:11:13 [LeeF]
- ... we have sent out a rechartering proposal to the AC that charters this group to produce a non-Rec track document (WG Note) called features & rationale that lists all the features we want in SPARQL
- 14:11:18 [LeeF]
- ... formal lifespan is through the end of July
- 14:11:51 [LeeF]
- ... in practice, group keeps doing what it is doing, but needs to publish this WG Note before end of July
- 14:12:03 [chimezie]
- zakim, mute me
- 14:12:03 [Zakim]
- chimezie should now be muted
- 14:12:21 [LeeF]
- ... as soon as we publish a first public working draft of requirements (hopefully 2nd half of May), we would immediately do a 2nd rechartering that lists the features as part of the charter
- 14:12:31 [SteveH]
- q+ to ask about process and schedule
- 14:13:10 [LeeF]
- ... if new charter proposal is done by end of May, it would be official by end of June, so from beginning-to-mid of July the group could be active under the second charter
- 14:13:43 [LeeF]
- ... no problem if group begins to really work on specification work in May - the only thing the group should not do is publish a First Public Working Draft because that is what leads to patent issues
- 14:13:56 [LeeF]
- ... no problem with editors' drafts
- 14:14:24 [LeeF]
- ack SteveH
- 14:14:24 [Zakim]
- SteveH, you wanted to ask about process and schedule
- 14:15:17 [LeeF]
- SteveH: my understanding around Lee's intentions was to iterate on the process - consider other things as time permits
- 14:15:27 [LeeF]
- ... but now we no longer have that flexibility
- 14:15:47 [ericP]
- i don't think we'll be any more bound later on than we would be in any other WG
- 14:16:11 [LeeF]
- ... if charter is bound, we can't go ahead and talk about details because that would be outside the charter
- 14:17:07 [ericP]
- q+ to say that this ends up being like any other WG
- 14:17:48 [LeeF]
- LeeF: intention is to reach consensus on 'required' and 'time permitting' deliverables, and then include them all in the new charter
- 14:18:03 [AndyS]
- q+ to aks about IP review at WD stages
- 14:18:39 [kasei]
- is everyone else hearing lots of (mobile?) interference on the call, or is it just me?
- 14:18:52 [SimonS]
- me too.
- 14:19:41 [ivan]
- ack ericP
- 14:19:41 [Zakim]
- ericP, you wanted to say that this ends up being like any other WG
- 14:20:06 [LeeF]
- ericp: we have patent policy since companies want to know what they're working on - the charter for the 2nd phase of the group ends up being like any other group
- 14:21:16 [ivan]
- ack AndyS
- 14:21:16 [Zakim]
- AndyS, you wanted to aks about IP review at WD stages
- 14:21:47 [LeeF]
- AndyS: HP was quite well aware of this issue and noted that there is a call for IP disclosures when a FPWD is published
- 14:22:28 [LeeF]
- ivan: Acknowledged; other groups are less flexible with respect to knowing potential IP issues
- 14:22:35 [LeeF]
- AndyS: will we all need to rejoin the WG?
- 14:22:39 [SteveH]
- wondering what the risk of not being rechartered is
- 14:23:04 [LeeF]
- ericP: I believe so.
- 14:23:40 [LeeF]
- AndyS: I don't think I could justify the new charter within my organization
- 14:24:29 [LeeF]
- ericP: I think for phase I we could continue the existing membership, but for phase II people would need to re-join
- 14:24:46 [SteveH]
- q+
- 14:24:50 [LeeF]
- AndyS: if there's no grace period it will be very rough
- 14:25:23 [LeeF]
- AndyS: concern about publication - editors' drafts have been publicly available in the past - the difference between editors' draft being publicly available and FPWD is not that big
- 14:25:43 [LeeF]
- ivan: difference is in commitment from WG and IP commitment
- 14:26:00 [LeeF]
- AndyS: I'm not sure if putting information in public exposes the editor's organization
- 14:27:05 [chimezie]
- zakim, mute me
- 14:27:05 [Zakim]
- chimezie was already muted, chimezie
- 14:27:07 [ivan]
- ack SteveH
- 14:27:17 [LeeF]
- ivan: if work is done on wiki as joint WG work, might not be an issue
- 14:27:43 [LeeF]
- SteveH: is there middle ground with a formal pause between 2 phases rather than a full rechartering? is this new standard operating procedure?
- 14:28:03 [Zakim]
- + +1.415.371.aaff
- 14:28:09 [LeeF]
- ivan: this occurred because the initial charter was too broad
- 14:28:19 [LeeF]
- ... might have been better with initial work as a short-lived XG
- 14:29:14 [LeeF]
- SteveH: it's not a guarantee that phase II will happen (get rechartered
- 14:29:20 [LeeF]
- s/rechartered/rechartered)/
- 14:29:28 [dnewman2]
- dnewman2 has joined #sparql
- 14:29:36 [LeeF]
- ivan: yes, that's a risk, we tried to avoid it but it didn't work out
- 14:29:48 [LeeF]
- zakim, aaff is dnewman2
- 14:29:49 [Zakim]
- +dnewman2; got it
- 14:30:15 [LeeF]
- SteveH: what happens if the AC rejects the rechartering?
- 14:30:42 [LeeF]
- ericP: The Director has some leeway. Given the current state of affairs, I don't see this as a significant risk
- 14:31:05 [AndyS]
- s/I don't think I could justify the new charter within my organization/I don't think I could justify the nwe charter without internal review within my organsiation/
- 14:36:01 [ericP]
- AndyS, SteveH, would a note to public-rdf-dawg would have make this better?
- 14:36:06 [SteveH]
- yes
- 14:36:30 [AndyS]
- No
- 14:37:07 [AndyS]
- Notifying current members before it went wide would have been helpful. Notify - not discuss.
- 14:37:23 [SteveH]
- yes, dicsussion is not neccesary

- LeeF: there has been a bunch of discussions on that
- 14:38:54 [ivan]
- chimezie, can you summarize?
- 14:39:25 [ivan]
- chimezie: the link has a descriptioin for the general requirements
- 14:39:50 [ivan]
- .. .last week we proposed the parametrization was used to describe the inference regime
- 14:40:00 [ivan]
- ... this would go beyond owl
- 14:40:11 [ivan]
- ... the wiki also mentions merging datasets
- 14:40:16 [LeeF]
- q+ to ask if merging datasets is the same as composite dataset issue
- 14:40:39 [ivan]
- ... from ontologies or rules into the graph
- 14:40:51 [ivan]
- ... that overlaps with the previous feature
- 14:41:06 [ivan]
- ... there was a possibility to break this thing into a separate feature
- 14:41:28 [ivan]
- ... the last thing is to parametrize whether an ent. regime would give all possible answers or not, for example
- 14:41:39 [ivan]
- ... the general idea is to parametrize the possible answers
- 14:42:06 [ivan]
- LeeF: is the topic of merging the same as composite datatypes
- 14:42:08 [AndyS]
- q+ to ask about protocol implications
- 14:42:12 [LeeF]
- s/datatypes/datasets
- 14:42:28 [ivan]
- chimezie: yes, but if you want an additional answers, do you have to bring the data in, for example
- 14:42:31 [ivan]
- q+
- 14:43:07 [ivan]
- LeeF: is it fair to say that the issue is giving all possible answers vs. not is a detail that can be worked out later, or has to discussed upfront
- 14:43:37 [SteveH]
- Zakim, who's talking
- 14:43:37 [Zakim]

- 14:47:47 [SimonS]
- ack.
- 14:48:22 [AndyS]
- Yes - service description is the service controlling things - this is query controlling things.

- ... people have been doing that for a while
- 14:56:16 [AndyS]
- ack AndyS
- 14:56:26 [LeeF]
- LeeF: there are other ways (rather than specifying in the query) to know that you are querying an endpoint that does SPARQL/OWL
- 14:56:31 [ivan]

- chimezie, you wanted to respond to LeeF
- 14:58:47 [ivan]
- chimezie: i think there is a confusion what this suggests and what bijan suggested
- 14:59:06 [ivan]
- ... the only thing is which particular entailment regime you use
- 14:59:36 [ivan]
- LeeF: my problem was the maturity of the different entailement regimes
- 14:59:56 [ivan]
- ... the interplay with the query language, how would you put it into the query language

- 15:01:00 [ivan]
- chimezie: if you separate the inclusion of ent regime from the answer itself,
- 15:01:11 [ivan]
- ... we need to standardize this
- 15:01:27 [ivan]

- dnewman2: end user prospective, we are talking about using sparql to dynamically trigger inferencing at the point of the query
- 15:02:22 [ivan]
- ... that to me is a very useful feature
- 15:02:35 [chimezie]
- Seems like there is 1) Which entailment regime should answers be conditioned on 2) Is this specified in the query langauge and/or the protocol 3) how are datasets composed
- 15:02:38 [ivan]

- q-
- 15:02:57 [ericP]
- dnewman2, would being able to choose between two endpoints which offered no entailment and entailmentX suffice for your needs?
- 15:03:14 [ivan]
- q+
- 15:03:29 [chimezie]
- I don't think SPARQL-DL requires (USING ... for example)
- 15:03:47 [SteveH]
- what about using entailments in some parts of the query and not others for example. is an example of something that curretn systems do, but this proposal does not address
- 15:03:48 [chimezie]
- it just expects additional answers to queries WRT OWL-DL entailment
- 15:04:12 [chimezie]
- SPARQL-DL being Bijan's proposal
- 15:04:48 [LeeF]
- ivan: Bijan's proposal [SPARQL/OWL] describes what answers to expect when querying under DL entailment
- 15:05:04 [LeeF]
- ... there are other entailment regimes
- 15:05:07 [ericP]
- foaf-smushing is a high-profile candidate entailment
- 15:05:11 [LeeF]
- ... no answer for how to choose it
- 15:05:20 [chimezie]
- SteveH: I'm not sure how you can specify the conditions on a query at such a level of granularity (i.e., specific parts of the query)
- 15:05:20 [LeeF]
- ... one possibility is multiple query endpoints
- 15:05:31 [LeeF]
- s/SteveH:/SteveH,/
- 15:05:45 [SteveH]
- chimezie, well, jena does that now I believe, and my old systems did too
- 15:06:01 [SteveH]
- chimezie, it's not really that hard, and quite essential
- 15:06:04 [SimonS]
- we do multiple graphs instead of multiple endpoints.
- 15:06:13 [SteveH]
- ditto
- 15:07:30 [AndyS]
- ditto
- 15:08:07 [SimonS]
- Views can then be used to combine the results from multiple graphs.
- 15:08:22 [SteveH]
- ivan, the proposal where you give an entailment regime for the whole query is sufficiently behind the state of the art that I don't believe it covers the common use-cases
