Luc: at SW coordination teleconf: debate on Web architecture takes majority of time and resources W3C-wide. We need to have time bounds
15:24:13 [paolo]
Luc: Luc and Paul identified few key points on which consensus is critically needed
15:24:47 [paolo]
Luc: following 5 proposals identified in the agenda
15:25:36 [Luc]
15:25:38 [paolo]
Luc: discussions on provenance model and provenance in the Web architecture are best kept separate at this time
15:25:40 [JimMyers]
+1 - is the mapping to web arch part of the access task force? or still model?
15:26:09 [Luc]
15:26:21 [paolo]
Luc: soliciting comments on this
15:26:27 [Luc]
15:27:02 [paolo]
GK: concerned that we may end up with different views that may be hard to reconcile at a later time
15:27:33 [paolo]
Luc: possibly so, but at least we will have made progress on both
15:27:33 [Luc]

Listening to this discussion: I would move to accept the proposal for now, but review in 2 weeks.
15:34:20 [stain]
GK, yup, sounds like the resource discussion is on again.. :)
15:34:31 [GK]
q+ to move to accept the proposal for now, but review in 2 weeks.
15:34:40 [dgarijo]
+1 to what satya said
15:34:42 [paolo]
satya: use journalism example to ground a concrete def. for resource, and then expand from there. Model and arch view may be reconciled in the context of the example
15:35:18 [paolo]
Luc: in practice issues have emerged recently precisely in the context of the example
15:35:39 [zednik]
+1 for separation of concept model from mapping to web architecture (access)
15:35:44 [Zakim]
15:36:09 [jorn]
q+ to propose to rename "provenance resource" so it isn't confused with web resource all the time?
15:36:22 [paolo]
satya: start with "resource" has anything we want to describe the provenance of (check?)
15:37:08 [Luc]
15:37:10 [paolo]
Luc: not yet clear what we mean by "provenance of a resource". leads to "mutable thing" vs "immutable thing"

ack GK
15:37:44 [Zakim]
GK, you wanted to move to accept the proposal for now, but review in 2 weeks.

15:38:40 [Luc]
15:39:02 [paolo]
GK: propose to accept proposal 1 with option to review in case a divergence is evident
15:39:23 [Luc]
15:40:04 [zednik]
+1 for renaming resource
15:40:12 [paolo]

agent was a special case (like PML:source) to capture the idea of a resource that could participate in processes (along the lines of my emails and wiki entries) - agent just couldn't be an artifact if they are completely immutable

I wonder what category is "otherwise"
15:49:11 [JimMyers]
conceptual, logical
15:49:38 [GK]
I wouldn't prohibit imaginary, conceptual at this time
15:49:45 [paolo]
YolandaGil: is the subject of provenance anything that we can refer to?
15:50:35 [tlebo]
anything to which one may want to refer.
15:50:53 [zednik]
15:50:56 [GK]
Yes, point taken about "can refer to" - maybe the TF can tighten up the definition?
15:51:00 [paulo]
in PML, we use the identifiedThing cncept (something that we can refer to)
15:51:03 [paolo]
YolandaGil: correct as "physical, digital, conceptual, or otherwise"?

proposed: the subject of provenance may be anything, whether physical, digital, conceptual or otherwise

15:52:24 [paulo]
if it is anything, can it be a thing that we cannot refer to?
15:52:25 [paolo]
15:52:47 [GK]
q+ to say I think its fine to focus on immutable resources but not to arbitrarily exclude mutable ones
15:52:51 [satya]
15:53:04 [paolo]
Luc: mutability seems to get in the way. Provenance of immutable things is a low hanging fruit. A few people made proposals
15:53:14 [JimMyers]
15:53:15 [jorn]
q+ to say we can't hinder people from issuing provenance about things which are mutable (web is a distributed system)
15:53:22 [paolo]
15:53:32 [Luc]
15:53:39 [paolo]
Luc: leading to proposal 3: "in a first instance, to define the necessary concepts that allow us to express the provenance of a thing that does not change"
15:54:12 [paolo]
GK: fine to focus on immutable resources initially. but not make immutability an a priori requirement
15:54:24 [GK]
15:54:26 [satya]
+1 for GK's point
15:54:31 [Luc]
15:54:38 [Luc]
ack satya
15:54:56 [paolo]
satya: what do we mean by immutable things?
15:55:36 [GK]
@satya Good question: it's kind of why I don't want to exclude the mutable.

15:56:45 [GK]
@satya, agree, focus on what's required

jorn, you wanted to say we can't hinder people from issuing provenance about things which are mutable (web is a distributed system)
15:57:40 [JimMyers]
15:57:57 [GK]
q+ to ask @JimMeyers what he meant by can't do one after the ther
15:58:41 [Luc]
15:58:43 [smiles]
15:58:57 [tlebo]
is there anything that is universally immutable? Roles seems to be a good approach.
15:59:19 [satya]
good point @jorn (good point on owl:sameAs)
15:59:39 [paolo]
jorn: if we restrict certain things to be immutable, that may be an artificial constraint that may not work for whoever uses the model
15:59:44 [JimMyers]
I don't know how to explain except in the context of my proposed 'solution' - mutability is a role of a resource w.r.t. a process - if that's a good model, I don't see how we could discuss immutability first and then change the definition of resource in some way to address mutability
16:00:11 [Luc]
16:00:14 [tlebo]

+jorn; got it
16:03:49 [GK]
@smiles like your phrasing "insofar as it's immutable we can talk about its provenance"
16:04:19 [paolo]
khalidbelhajjame: if we tackle mutability at a later time, that may lead to revisiting many other definitions
16:04:37 [JimMyers]
if the question is whether we should have a way other than resources to describe changes in state - +1 - there's a role for mutable resources but we don't need a mechanism to define state changes of mutable resources separt from defining immutable resources that encapsulate that state (but are just resources)
16:04:52 [Luc]
16:05:26 [Luc]
16:05:31 [paolo]
paolo: isn't that the case that things that do not change only have a provenance if they have changed in the past? I am confused
16:05:43 [frew]
"WORM" resource?
16:05:52 [satya]
I think we need more discussion - over mailing list?
16:05:55 [GK]
Agree in principle with wjhat we discussed
16:05:59 [paolo]
Luc: is there a consensus?
16:06:09 [JimMyers]
-1 - I'd like to discuss things together...
16:06:17 [jcheney]
what's the formal proposal now?
16:07:04 [satya]
Proposal: we do not make assumption about mutability/immutability of object
16:07:19 [zednik]
+q statement about mutability
16:07:37 [kai]
I think we have too many mutable resources out there so I would try to deal with them from the beginning.
16:07:45 [paolo]
satya: a few things not clear, but we can go with mutability/immutability in the context of the running example
16:07:49 [Luc]
16:08:03 [Luc]
16:08:25 [GK]
@satya broadly agree with "Proposal: we do not make assumption about mutability/immutability of object" but would add "unless the use-case requires us to"
16:08:59 [paolo]
JimMyers: the distinction is significant in the context of (relative to) processes. possibly this pov gives us a way forward in the discussion
16:09:00 [Luc]
would it help if we said state of a thing
16:09:12 [Luc]
instead of a thing that does not change
16:09:12 [dgarijo]
even the example has "mutable things", so it will be difficult to leave them out of the discussion
16:09:16 [satya]
@GK agree, if required for use case
16:10:32 [paolo]
action: JimMyers, satya to formulate proposals that we can vote on next week
16:10:32 [trackbot]
Sorry, couldn't find user - JimMyers,
16:10:34 [JimMyers]
I put a 'definition' of resource on the wiki page just before the call - that's my proposal for a model
16:10:54 [JimMyers]
Perhaps I could try to apply that to the use case to make it clearer...
16:11:28 [jorn]
subject ?
16:11:34 [satya]
16:11:37 [zednik]
16:11:42 [paolo]
Luc: term "resource" not useful here as too loaded as architectural term
16:11:43 [kai]
+1 for entity
16:11:51 [GK]
"Subject of provenance" (Luc's phrase from an earlier proposal)?
16:12:07 [paulo]
16:12:24 [Luc]
16:12:26 [paolo]
+1 for >"Subject of provenance" (SoP)

16:14:59 [Luc]
16:15:07 [paolo]
Luc: true, but not current topic
16:15:09 [stain]
mutability is very related to identifiable - depending on how you identify it might be mutable or immutable
16:15:39 [kai]
Maybe it would be doable to restrict provenance to immutable subjects and provide ways to see mutable subjects as immutable, e.g. by adding a version or a timestamp.
