Some comments to provided by email. 2nd scenario provenance of provenance but 3rd scenario might lead to a recommendation - usable as a record 15:13:22 Yolanda: Provenance as a record - not using that exact terminology - need to be able to express the provenance of provenance - maybe refine this 15:14:31 Is selective disclosure a recommendation? 15:14:43 Yolanda: propose as a separate recommendation 15:15:48 Yolanda: See recommendation 3 - I thought we agreed - 1st scenario core requirements, 2nd adds to that and 3rd adds to that - assume if in 1st scenario will be relevant to the others 15:16:28 Discussing mechanism to show provenance has not changed 15:17:01 Immutability vs, non-repudiation of provenance 15:17:36 Signable provenance for non-repudiation 15:19:12 Conclusion? - the 3 management points are already covered by recommendations 2 and 3? 15:19:20 Yolanda: yes, 2, 3 ,4 15:20:26 [inaudible] 15:21:05 +q 15:21:07 q- 15:21:14 ack 15:21:17 q- 15:21:29 Yolanda: Re disease outbreak scenario - those 2 recommendations were the major ones 15:22:28 Yolanda: We did not discuss last week - the use of policies mentioned in the scenario 15:23:35 q+ 15:23:40 Yolanda: This scenario highlights more data aggregation (from different sources) - should we have an item that specifically states this - provenance may be more detailed - more vocabulary may be needed? 15:25:00 Irini: For disease outbreak scenario - important to mention data integration - database area there has been a lot of work re provenance at different levels of granularity - queries - we should look at the work done for relational databases 15:25:08 q- 15:26:30 q+ 15:26:34 Yolanda: We have not highlighted time or the issue of handling different versions of information as it changes over time - wonder if it should be captured somewhere 15:27:41 ? question about time - time of artefact may not match the time you record the provenance 15:28:44 Yolanda: in the 2nd recommendation we mention time 15:29:06 Yolanda: we need to be more specific which time 15:29:26 Paolo: Need to have the distinction to work in different ways 15:29:46 ? May be captured by recommendation 4 15:29:59 Yolanda: We will make that more explicit 15:30:10 Paul: related to time is the notion of versioning 15:30:23 zakim, unmute me 15:30:23 smiles should no longer be muted 15:30:29 q+ 15:30:29 Paul: Does it come up in the business case scenario? 15:30:49 Yolanda: yes - in the last paragraph of the disease outbreak scenario 15:31:14 -krp 15:32:01 q+ 15:32:10 Paul: recommendation 5 is very specific but 1-3 recommendations (coarse grained provenance) then there is versioning 15:32:28 Yolanda: Maybe useful to have something about versioning 15:32:41 ack pgroth 15:32:43 Paul: or mention versioning in the explanation of recommendation 5 15:32:53 ack pgroth 15:33:00 - +1.915.603.aabb 15:34:03 ? in the OPM profile space - would argue should go out to standard ontologies 15:34:13 re versioning 15:34:15 q- 15:34:40 +krp 15:34:42 ? business contract scenario raise versioning 15:35:34 Is there is a connection between granurality of provenance and versioning? 15:36:24 Paul: Need to resolve what we are going to say re versioning 15:36:33 sorry, but i'd better go. thanks, simon 15:36:39 -smiles 15:36:48 I think we should mention versioning explicitly in the recommendation 15:36:58 + +1.915.747.aaee 15:37:05 Yolanda: If look at recommendations as they are now - we need a theme and all these would be themes - maybe provenance is important for the web and recommend pursue provenance in these ways ... 15:37:22 Yolanda: Different priorities for recommendations? 15:37:39 +1 for attaching priorities 15:38:32 +1 15:39:01 Yolanda: Core of provenance representations for the web? and maybe extensions 15:39:57 I think recommendation 1,2,3, and 7 have higher priority than others 15:40:14 Paulo has joined #prov-xg 15:41:09 Satya: how to represent the provenance information (1) and (2) how to access provenance and (7) 15:41:45 Sam: Like the idea of versioning - might be good to keep manageable by prioritising them 15:42:03 http://www.w3.org/2005/Incubator/prov/wiki/Recommendations_for_scenarios 15:42:10 http://www.w3.org/2005/Incubator/prov/wiki/Recommendations_for_scenarios 15:42:36 Paul: Priority 1 is rec 3 then 1 then 2 15:44:04 Paulo: we need to revisit some of the foundations 15:44:35 Yolanda: perhaps an email to the list with details 15:44:58 Paolo has joined #prov-xg 15:45:07 I just got temp disconnected 15:45:14 but have been on the phone 15:45:29 Luc: broadly in agreement with Paul re priorities - but need to do at a higher level - provenance is very broad - solve core but not everything 15:46:34 Yolanda: which items would be more amenable to be part of the core? 15:46:49 Luc: agreed with Paul's prioritization 15:47:42 I would suggest 1, 3, 2 for the core 15:48:11 Jun: rec 4 - 7 seem to be quite specific - before we can do that we don't have the foundation for the semantic web community - standardisation of representation of provenance info - 3 and 1 are my priorities 15:48:44 3 isn't query, it's access 15:48:57 Paolo: rec 1, 2, 3 are the baseline/foundation - placeholders 1 for data model, 2 .. 3 being open to other models - they are the baseline 15:48:58 would hate to specify a query mechanism 15:49:02 IMO 1,3,2 first, then 5,6,4,7 15:49:51 core, integration with DC, versions, metadata, records, access control 15:50:42 Jim: generally agree that there is some core of things going through processes - integration with external metadata needs to be there - records is something we have not addressed a lot and is a key thing (particularly for business) 15:51:23 Jim: some things around reasoning and granularity 15:52:09 what's out for standardization - reasoning between witnesses, assessing reproducable research, inference over granularity 15:53:20 Irini: agree with Luc and Paolo - priorities are different for different contexts - e.g. 5 then 3 for linked data SPARQL 15:54:40 +q 15:54:55 Yolanda: clear focus of the group 1, 2 ,3 in different orders - Paolo summarised quite well - data model, query model and open model 15:54:57 +q 15:55:14 Yolanda: other areas require more work, more research 15:55:34 ack smiles 15:55:51 is it query model or query language? 15:55:59 designing a query language is a hard task! 15:56:06 Paul: a query model/approach - I though the recommendation was about access or making information available - prefer not to call query 15:56:21 Paul: difference between access and query language 15:56:23 q+ 15:56:25 ack pgroth 15:56:25 ack pgroth 15:56:29 ack Luc 15:56:30 Luc: agree 15:57:08 q+ 15:57:18 ack Paolo 15:57:41 access vs. retrieval mechanism? 15:57:48 Paolo: access is too broad - there should be an element of selectivity - to be able to specify what you want - query too specific 15:58:38 ack Paolo 15:58:41 ack Irini 15:59:38 Irini: explaining previous comment ... sparql language can be used for queries to produce provenance information - want fined grained so I can reproduce my results... 16:00:23 Yolanda: pls write a paragraph to illustrate that different recommendations may be relevant for different circumstances 16:00:36 - +1.915.747.aaee 16:01:43 http://www.w3.org/2005/Incubator/prov/wiki/What_Is_Provenance 16:02:15 Yolanda: useful call - discuss provenance defn next time - we have a page on the website (see agenda) - it has a few definitions - question is whether we will be able to come up with one defn as a group 16:02:58 Christine: for outside the provenance community it would be helpful to have one definition 16:03:28 -krp 16:04:07 Yolanda: we will discuss this next week - also look at what provenance is not 16:04:14 Yolanda: thank you 16:04:19 -[IPcaller] 16:04:20 -jun 16:04:23 - +1.216.368.aaaa 16:04:25 - +30281039aadd 16:04:27 -JimM 16:04:29 -Paolo 16:04:31 -??P30 16:04:31 Christine: i'll take on from here, many many thanks for scribing!! 16:04:34 -??P18 16:04:36 - +46.6.43.0.aacc 16:05:01 ScribeNick: Christine 16:05:11 rrsagent, set log public 16:05:18 rrsagent, draft minutes 16:05:18 I have made the request to generate http://www.w3.org/2010/09/24-prov-xg-minutes.html YolandaGil 16:24:42 -YolandaGil 16:24:44 INC_PROVXG()11:00AM has ended 16:24:45 Attendees were smiles, JimM, Paolo, [IPcaller], krp, YolandaGil, +1.216.368.aaaa, jun, +1.915.603.aabb, +46.6.43.0.aacc, +30281039aadd, +1.915.747.aaee 16:56:22 trackbot, end telcon 16:56:22 Zakim, list attendees 16:56:22 sorry, trackbot, I don't know what conference this is 16:56:23 RRSAgent, please draft minutes 16:56:23 I have made the request to generate http://www.w3.org/2010/09/24-prov-xg-minutes.html trackbot 16:56:24 RRSAgent, bye 16:56:24 I see no action items
