Paul suggested separating the collections out of the PROV-O document 15:12:54 ... Separately, Graham suggested restructuring DM 15:13:10 ... Last week, requested concrete proposals for restructuring 15:13:21 http://www.w3.org/2011/prov/wiki/ProvDM_Proposal_for_restructuring 15:14:13 GK: Proposal is in some ways quite radical, and is focused around separating central provenance patterns from those for specific processes 15:14:57 ... The rationale is to achieve (1) separate core provenance patterns from specific applications, for comprehensibility of core idea 15:15:51 -??P50 15:15:54 ... (2) Maximising interoperability with other systems doing provenance-like things 15:17:03 ... other models including provenance seem to include core matching the core DM patterns 15:17:42 apropos of GK's "core" patterns... this came to my eyes today -- http://linkedevents.org/ontology/ 15:17:43 ... (3) Minimising ontological commitment of users of model, so core embodies little semantics but captures essentials of traceability 15:18:15 ... Core: entity, activity, agent 15:18:45 Luc: Your proposal is to break DM document in two? 15:18:48 GK: Yes 15:18:51 q? 15:19:08 paolo? 15:19:15 just on irc? paolo? 15:20:02 http://www.w3.org/2011/prov/wiki/Collections 15:20:13 tlebo: Other proposal (linked above) from Paolo 15:20:57 ... collections and dictionaries taken out of PROV-O, classes and properties, and put into separate PROV-O-C document 15:21:03 ... aim to simplify PROV-O 15:21:06 sorry guys text only, 15:21:10 and very unstable 15:21:37 ... PROV-O team discussed on Monday, preferred to focus on the content of PROV-O rather than deconstructing 15:21:40 thanks smiles for minuting 15:21:44 I can fit http://www.w3.org/TR/prov-o/#description-collections-terms into 1.25 screens. http://www.w3.org/TR/prov-o/#description-qualified-terms takes up 4 screens. http://www.w3.org/TR/prov-o/#description-starting-point-terms takes up 1.5 screens 15:21:48 @paolo, it's ok, tim filling in 15:22:31 ... Have responded to reviews by simplifying content on collections 15:22:35 yes I know Tim questions the motivation for this ripping exercise 15:22:57 ... PROV-O team prefers to keep collections in PROV-O document 15:23:16 we seemed to agree that it's for the prov-o team to pursue this if they want 15:23:30 Luc: After last telecon, Paul and Luc considered logistics of taking collections out of existing documents to make new document 15:24:08 ... short of editors and bandwidth, and goes beyond scope of original charter to give application specific extensions 15:24:36 ... that is why Paolo suggested just extracting from PROV-O 15:25:17 ... Tim, are you proposing not separating, as length concerns are already being addressed? 15:25:20 tlebo: Yes 15:25:28 (and that was the agreement of the prov-o team) 15:25:41 q? 15:25:56 Luc: We have proposals to not do anything on restructuring or Graham's proposal 15:26:04 q+ 15:26:55 tlebo: From explaining to other people, people latch onto those core concepts 15:27:06 ... (as in section 1 of Graham's document) 15:28:24 tlebo: What about components (organisational structure of current draft)? 15:28:36 http://www.w3.org/TR/prov-dm/#data-model-components 15:28:46 GK: Tried to stick with existing material, suggest grouped in different way 15:28:51 ack tlebo 15:28:52 q- 15:29:30 Luc: Structure proposed is more or less what we had two iterations ago, but sections in one document 15:29:40 ... but had reviews critical of this separation 15:29:57 ... so decided to reorganise to remove distinction of core and extension 15:30:23 Paolo has joined #prov 15:30:32 ... seems to be going back, and when we get to justifying what is core, what is extension, we will have difficulties 15:31:01 ... Second, have had feedback from people outside WG who found component structure useful 15:31:18 ... so reluctant to abandon it if we split document 15:31:44 ... Third, if restructure PROV-DM, then have to do the same in other documents 15:32:11 ... lead to a multiplication of documents, as scary as large number of concepts in current model 15:32:17 what is background of these outside readers? philosophers, scientists, programmers, other? experience and grounding matters to whether the current structure is easy to understand... 15:33:00 ... There are sub-types, e.g. wasRevisionOf subtype of wasDerivedFrom, and could make more explicit in structure of DM 15:33:47 ... For example, derivations in section 6.3.1, could then have subsections for subtypes 15:34:01 ... (4.3.1 not 6.3.1) 15:34:53 ... or explicit marker for terms that are core, e.g. communication is not primitive as can be described in terms of generation and usage 15:35:40 q? 15:35:43 q+ 15:36:36 satya: As MacTed wrote above, who are the readers of the documents? which reviewers? 15:36:44 q+ 15:36:48 q- 15:37:00 Zakim, unmute me 15:37:00 MacTed should no longer be muted 15:37:01 Luc: In this case, researchers he works with who've implemented data model, felt component structure helped 15:37:44 MacTed: That kind of feedback is not very useful, need more kinds of audience 15:37:59 ... in favour of GK's restructuring 15:38:24 ... for PROV-O, does not seem to have discerned what is a sub-class of what, what are the overarching elements 15:38:51 ... there really are core concepts, and refinement of those 15:39:26 perhaps if we organized http://www.w3.org/2011/prov/wiki/ProvDM_Proposal_for_restructuring#Provenance_core_concepts by components? 15:39:26 q? 15:39:30 ack mact 15:39:56 ... root primitives need to be clearly presented 15:40:25 Luc: Agree that root primitives need to be clearly presented 15:40:28 q? 15:40:37 q+ to say I'll respond oif there arter no other comments 15:41:43 GK: Responding to Luc's point, looking at document two iterations ago, while separation of core from other concepts, too much other clutter so organisation wasn't serving purpose 15:42:31 ... Added rationale to his proposal of separation of core pattern, with principles clear 15:43:19 q+ to ask what if graham incorporated components into his outline? 15:43:23 ... With regard to restructuring other documents, don't see need to do so, just restructure DM, leave others as they are 15:43:34 ... PROV-O already does the job of pulling out core patterns 15:43:45 q+ to say I need to leave at 5 so can we discuss the prov-constraints review briefly before spending the rest of the meeting debating restructuring 15:44:32 ... Regarding changing presentation, mixing text on subtypes with supertypes would be exact opposite 15:44:39 ... of what is intended 15:44:40 @jcheny, I'll yield :-) 15:45:14 ... To have to dig around in document for core ideas means much less likely specification would be deployed 15:45:22 q? 15:45:22 q- 15:45:30 q- 15:45:46 ack jcheney 15:45:46 jcheney, you wanted to say I need to leave at 5 so can we discuss the prov-constraints review briefly before spending the rest of the meeting debating restructuring 15:45:56 topic: constraints document 15:46:08 go ahead, graham. 15:46:28 high-level impression is fine 15:46:41 GK: Looked through constraints document, feels a lot tighter and has right approach 15:46:54 ... definitions and inferences presented crisply 15:47:10 ... may be able to make more comments later, but looking good 15:47:35 tlebo: Biggest concern on last iteration was about getting into content 15:47:48 http://www.w3.org/2011/prov/wiki/Dm-constraints_review_2012_May_17_by_Lebo 15:47:50 ... this version is much better organised, natural to know where to go 15:48:20 ... minor detailed comments sent (above) 15:49:17 jcheney: Thanks, was really looking for high level impression, thanks for going through in more detail 15:49:27 ... good to know happy with direction 15:49:59 I think the style of revised -CONSTRAINTS will nicely complement a less formal description of -DM 15:50:06 @jcheney, sorry, I missed your questions in the email :-) 15:50:16 ... after last week had more specific questions, implicitly answered in Tim's comments, but please look at questions in email 15:51:16 @jcheney, I'll respond to the email questions after this meeting. 15:51:27 ... will go through issues raised to see what can be closed 15:51:30 q? 15:52:05 Topic: Responsibility 15:52:18 http://www.w3.org/2011/prov/wiki/Renaming_the_concept_Responsibility 15:53:01 tlebo: In definitions of assocation and attribution are responsibility, so name Responsibility is confusing and misnamed 15:53:34 I may have suggested "delegation" at some point 15:54:03 ... Wiki page comments above to prompt discussion by email 15:54:16 is there an issue raised for responsibility? 15:54:37 topic: bundles 15:54:46 http://dvcs.w3.org/hg/prov/raw-file/default/model/working-copy/wd6-bundle.html 15:55:03 Luc: Circulated text addressing issues raised
