People have offered to add usecases in the next few days. 16:09:22 olaf has joined #prov-xg 16:10:22 yolanda: add comments to discussion pages of wiki. Maybe have usecase editors to work with proposer to refine the usecase, make sure there is enough detail, or merge two related usecases. 16:10:54 yolanda: any volunteers for usecase editors ? 16:11:22 I am not sure where we're supposed to comment? on each use case page itself? 16:11:47 yolanda: a glossary of terms to keep track of terms that we use 16:12:11 ... going through each use case. 16:12:59 yolanda: 1. Simple Trustworthiness Assessment - Olaf is proposer 16:14:21 q+ 16:14:29 q+ 16:14:33 luc, i think, if you have comments on a use case you can do that in the discussion section of the use case 16:14:58 q+ 16:15:52 http://www.w3.org/2005/Incubator/prov/wiki/Provenance_Dimensions 16:16:51 Olaf: Alice publishes Bob's and Carol's data, she is not the provider of the data. So there are different trust relations that the consumer/user of the data, Eve, uses to decide whether or not to use the data. Dimensions: Attribution (Alice provides and manipulates data, Bob and Carol who provide the data), Publication (how to publish this provenance info), Use (Understanding?), Trust (application filters data based on trust). 16:17:08 zakim, +1.614.592.aaee is really michaelp 16:17:08 +michaelp; got it 16:18:41 Luc: the use case should be expressed without the concept of provenance. 16:19:32 q+ 16:20:22 michaelp has left #prov-xg 16:20:47 Luc: this usecase is good because its connected to different dimensions and is strongly related to Linked Data. There is a lot of interest in RDF community to associate triples with provenance and I wonder if this usecase is influenced by that. Should we try to express usecases without such a dependence on technology and without assuming the provenance concept ? 16:21:18 (Luc, I'm not sure I captured all your comments/questions, pls add anything I missed) 16:21:19 michaelp has joined #prov-xg 16:23:45 Simon: One of the purposes of usecase is to find technical challenges. It would be good to if the owners of each use case added the technical challenges for each usecase. 16:25:29 jcheney: I agree that provenance shouldn't assumed in the use case. Is there a difference between trust and filtering in this use case ? 16:26:04 olaf: consumer makes the judgement whether to filter or not but uses information related to provenance to make that decision 16:26:06 q+ 16:26:17 ack Luc 16:26:20 ack smiles 16:26:26 ack jcheney 16:27:11 yolanda: maybe usecase could talk about trustworthiness assessment and then talk about how it would apply to different domains - LOD, escience etc. 16:27:44 olaf: Linked Data Timeliness. A dataset that changes frequently. Two publishers use this data to make and publish their own dataset. 16:29:08 zakim, who is there 16:29:08 I don't understand 'who is there', michaelp 16:29:12 q+ 16:29:43 zakim, who is here 16:29:43 michaelp, you need to end that query with '?' 16:29:47 zakim, who is here? 16:29:47 On the phone I see ssahoo2, ??P2, pgroth, +1.518.276.aaaa, YolandaG, ??P12, +1.781.646.aacc, +49.302.093.aadd, michaelp, +0238059aaff, ??P24 (muted), ??P25, +1.609.462.aagg, Ivan, 16:29:50 ... ??P28, +1.915.747.aahh, jmccuske, [IPcaller], +1.530.554.aajj 16:29:51 On IRC I see michaelp, olaf, ludaesch, Paulo, RRSAgent, Zakim, afreitas, Paolo, smiles, lkagal, Aleksey, Deborah, jcheney, pgroth, jmccuske, YolandaG, ssahoo2, ivan, trackbot 16:30:16 q? 16:30:57 olaf: Application accesses data provided by these publishers and uses provenance such as time to decide whether to use this data. Dimensions: process, creation time, data accessed time (new one) how and when data was accessed includes when publisher accessed the data, republishing, trust (filters data based on timeliness). 16:31:40 olaf, why isn't this timeliness problem fall under the updates category? 16:31:52 Paulo: +1 Luc. The usecase does not necessarily highlight problems. 16:32:29 +1 Paulo 16:32:52 Paulo, I missed that, please could you add it. 16:33:31 +q 16:33:54 Paolo: Strong focus on LOD, maybe not required. Should generalize the usecase. 16:34:28 Paul: Olaf, you want to introduce another dimension of data access. Why does update not include this ? 16:34:35 ack paulo 16:34:39 ack paolo 16:34:43 ack pgroth 16:35:15 q+ 16:35:30 Olaf: The provider of the data may not be the creator, update is related to creation. But the provider is not creating it but accessing it for publishing. 16:36:53 Yolanda: Time is only one aspect of this, there are other aspects. 16:36:56 understanding trust itself may be a distraction for the group to understand the role of provenance in support of trust 16:38:06 -[IPcaller] 16:38:22 michaelp: usecase is about reliability assumption and not so much about timeliness. 16:38:33 +??P17 16:39:14 q+ 16:39:24 Yolanda: We need a glossary of terms. Reliability means something different to me. Time is crucial to provenance and we need to highlight it somehow. 16:39:33 ack michaelp 16:40:31 Olaf: I agree with Michael. Similar to the trust case, we had a model to calculate trust in this case we have a model to calculate timeliness. 16:40:37 acl olaf 16:40:42 ack olaf 16:41:52 Simon: Result Differences use case. Process is imp thing. Management issue - large historic data, imperfection and debugging. 16:43:15 yolanda: is there a usecase where comparing different results would matter. 16:43:43 ... in a different domain 16:44:49 +q 16:44:54 :-) 16:45:39 ack pgroth 16:46:59 pgroth: Blogosphere usecase. Aggregating blogposts. Question: when you aggregate diff posts and discussions, how do you traceback to where the original data came from. 16:47:42 q+ 16:47:53 Yolanda: content evolution, republishes, who is responsible for publishing, is it a requirement, can someone reconstruct the provenance. 16:48:40 pgroth: republishing, interoperability 16:49:31 q+ 16:50:02 q+ 16:50:10 Mark: Re cross references mostly circular references. I'll post related paper. 16:50:34 ... I'll add this use case 16:51:23 ack pgroth 16:52:33 zakim, who is noisy? 16:52:44 ivan, listening for 10 seconds I heard sound from the following: YolandaG (23%), +1.781.646.aacc (27%), +1.609.462.aagg (56%) 16:54:10 Yolanda: timeliness is not a matter of publishing but during the use itself, how provenance is used by consumer. 16:55:01 http://www.w3.org/2005/Incubator/prov/wiki/Talk:Provenance_Dimensions 16:55:14 ssahoo: For dimensions I had suggested agents and adding temporal and spatial dimensions. 16:55:40 q+ 16:55:50 ack ssahoo 16:55:53 Paolo: Track how a community came to a scientific conclusion. Should there be another use case. 16:55:57 ack Paolo 16:56:57 q+ 16:57:27 ack pgroth 16:57:36 pgroth: Having a scientific aggregation use case would be good to have. Provenance of blogosphere, tweets, and scientific aggregation are related and might lead to a common/general use case. 16:58:00 Yolanda: volunteers for usecase editors ? 16:58:21 I will be happy to help in editing the use cases 16:58:24 Simon: yes 16:58:52 Paolo: yes 16:59:17 q+ 16:59:25 ack ssahoo 16:59:33 q+ 16:59:34 ssahoo: will we be discussing dimensions ? 16:59:53 Yolanda: lets work on usecases first and then refine dimensions 17:00:16 can we talk about the dimensions on the email list? 17:00:18 Yolanda: glossary editor ? 17:00:19 ack pgroth 17:00:28 Luc has joined #prov-xg 17:00:47 yolanda: should we raise the issue of a face 2 face meeting? 17:00:52 q+ 17:01:26 Paul: we are posting comments on the dimensions in the discussion tab 17:01:28 -pgroth 17:01:35 that's true 17:01:42 so a good place to do it 17:02:47 we can always have complementary discussions on the mailing list 17:02:56 -ssahoo2 17:02:57 -jmccuske 17:02:57 - +0238059aaff 17:02:57 zakim, drop me 17:02:58 Ivan is being disconnected 17:02:58 -Ivan 17:02:58 -??P28 17:02:59 bye 17:02:59 -??P24 17:02:59 pgroth has left #prov-xg 17:03:00 afreitas has left #prov-xg 17:03:00 -??P12 17:03:02 -??P25 17:03:05 -??P17 17:03:06 - +1.609.462.aagg 17:03:08 -YolandaG 17:03:11 - +1.530.554.aajj 17:03:13 - +49.302.093.aadd 17:03:15 - +1.781.646.aacc 17:03:17 -??P2 17:03:18 -michaelp 17:03:21 - +1.915.747.aahh 17:03:23 - +1.518.276.aaaa 17:03:25 INC_PROVXG()11:00AM has ended 17:03:27 Attendees were +1.518.276.aaaa, +1.860.995.aabb, +1.781.646.aacc, +49.302.093.aadd, +0238059aaff, +1.609.462.aagg, Ivan, +1.915.747.aahh, YolandaG, ssahoo2, pgroth, [IPcaller], 17:03:29 ... +1.530.554.aajj, jmccuske, michaelp 17:03:52 jmccuske has left #prov-xg 17:04:34 Yolanda, should I create the minutes and put them on the wiki ? 17:07:07 olaf has left #prov-xg 17:09:11 rrsagent, draft minutes 17:09:11 I have made the request to generate http://www.w3.org/2009/12/04-prov-xg-minutes.html lkagal 17:11:14 zakim, bye 17:11:14 Zakim has left #prov-xg 17:11:24 rrsagent, bye 17:11:24 I see no action items
