15:24:26 [Luc_]
15:24:41 [TomDN]
Luc: specifications will be out next thursday, so time for the blog should be shortly after that
15:24:45 [Luc_]
topic: Definition of Alternate and Specialization
15:25:12 [TomDN]
Luc: there were many discussions about alt/spec.
15:25:31 [TomDN]
... Solution should have support of the whole WG.
15:26:12 [TomDN]
... If no consensus can be had, we follow the agreed procedure, and drop them from specification, and add them as notes
15:26:33 [Luc_]
15:26:37 [Zakim]
15:26:47 [TomDN]
... TomDN, Jim, james and chairs discussed this via email/wiki
15:27:36 [TomDN]
... Definition 13 is something they are happy with, and ask for support from the group. Vote will be next week
15:27:45 [stephenc]
stephenc has joined #prov
15:28:12 [TomDN]
... hopefully this will close the issue. If not, we will discuss more, but they will be dropped from the documents and added as notes.
15:28:33 [TomDN]
JimMcCusker: We went through a number of iterations
15:28:47 [TomDN]
... trying to define clearly what an entity is
15:28:58 [stain2]
stain2 has joined #prov
15:29:03 [stainMobile]
stainMobile has joined #prov
15:29:12 [TomDN]
... we agreed that an entity is something we use to talk about things in a particular way.
15:29:13 [Zakim]
15:29:28 [TomDN]
... explains definitions.
15:29:39 [stainMobile]
Zakim, ??P2 is me
15:29:39 [Zakim]
+stainMobile; got it
15:29:51 [stainMobile]
Zakim, ??P2 is stain
15:29:51 [Zakim]
I already had ??P2 as stainMobile, stainMobile
15:30:02 [TomDN]
... We leave things open for alternates to be very distinct ways of looking at the same thing.
15:31:13 [TomDN]
... Special attention paid to lifetime of entities.
15:31:41 [GK]
exists general => exists specialization? Other way round?
15:32:16 [GK]
AHh.. I get it...
15:33:56 [JimMcCusker]
An entity is a physical, digital, conceptual, or other kind of thing with some fixed aspects. Entities may be real or imaginary. (same as above)
15:34:04 [JimMcCusker]
Two alternate entities present aspects of the same thing. These aspects may be the same or different, and the alternate entities may or may not overlap in time. (changed has to presents; rearranged & added time)
15:34:12 [JimMcCusker]
An entity that is a specialization of another entity shares all aspects of the latter, and additionally presents more specific aspects of the same thing as the latter. In particular, the lifetime of the specialized entity contains that of any specialization. (changed has to presents; rearranged & added time)
15:34:44 [TomDN]
TomDN: Pros of the definitions are: they avoid discussion about reflexivity/transitivity like we had before. Also they require minimal changes to existing documents
15:34:56 [TomDN]
Luc: They are a good compromise.
15:34:59 [Luc_]
15:35:07 [khalidbelhajjame]
15:35:22 [stainMobile]
I wA
15:35:54 [TomDN]
kh: main difference is in definition is in alternateOf. More specifically, the overlapping/non-overlapping intervals.
15:36:02 [Curt]
I like emphasis on "aspects". Key to understanding will be good examples...
15:36:14 [TomDN]
... Concerns that "aspects" will be confusing.
15:36:25 [Luc_]
15:36:28 [Luc_]
ack kh
15:36:44 [TomDN]
JimMcCusker: We settled on aspects because it's the most efficient way to talk about everything an entity can be
15:36:55 [stainMobile]
Wander slightly what is the meaning of alternate , first line says entity is a thing, second that entity a aspect
15:37:04 [TomDN]
... It's not an exclusive view, but also not a fixed set of attributes
15:38:01 [TomDN]
... the meaning is that of the natural language meaning of aspects. No special definition required.
15:38:21 [Luc_]
15:38:46 [TomDN]
kh: Why was it necessary to relax the definition of alternate to non-overlapping intervals.
15:39:15 [Luc_]
15:39:19 [TomDN]
Luc: this is to accomodate examples like the "customer in chair at 6pm or 7pm" one
15:39:45 [TomDN]
Luc: Vote will be next week
15:39:52 [Luc_]
topic: Collections
15:40:37 [TomDN]
Luc: Update on current status: Collections are now called Dictionaries in the DM
15:40:51 [khalidbelhajjame]
@Luc, yes
15:41:06 [TomDN]
... Changes are made to prov-o document as well.
15:41:22 [stainMobile]
There might be a few Collections hanging about still :)
15:41:28 [JimMcCusker]
I need to drop off, thanks all!
15:41:29 [TomDN]
Jim: Acknowledges that these changes are being made today
15:41:46 [tlebo]
( still needs to be updated to reflect the name change)
15:41:53 [TomDN]
Luc: Do we want another, concrete kind of collection in the model?
15:41:55 [JimMcCusker]
15:42:08 [Luc_]
15:42:12 [khalidbelhajjame]
15:42:18 [Zakim]
15:42:38 [TomDN]
kh: One way to try to answer this is to look what kind of provenance is required.
15:42:48 [TomDN]
... do we need order, duplicates, ... ?
15:43:24 [TomDN]
kh: Dictionary as it is now is very general. Can be mapped to most possible collections when required
15:43:41 [TomDN]
... So most cases will be covered already.
15:43:53 [tlebo]
q+ to say that "Collections" have always been defined as "Dictionaries", so adding anything other than a Dictionary is feature creep. Leave Collections as the hallow superclass.
15:44:00 [Luc_]
ack kha
15:44:07 [TomDN]
... As they are now, dictionaries are very expressive, which is great.
15:44:37 [tlebo]
15:44:57 [TomDN]
tlebo: Collections actually always were Dictionaries, except for the name.
15:45:38 [TomDN]
... adding more features would be feature-kreeped
15:45:48 [TomDN]
(spelling of that last one? )
15:45:56 [Luc_]
15:46:05 [GK]
(I'm staying silent for now, as my earlier email seems to have struck a nerve and I'm considering my response.)
15:46:06 [stainMobile]
15:46:17 [TomDN]
Jun: agrees, adding more would make the model look more like a datastructure
15:46:41 [TomDN]
15:47:04 [TomDN]
GK: Still not completely convinced that we need Collections. Simpler is better.
15:47:05 [Luc_]
15:47:05 [tlebo]
@gk, you mean Dictionaries?
15:47:33 [tlebo]
@gk @luc thx
15:47:44 [GK]
(I mean any kind of collection)
15:47:50 [Luc_]
Proposed: not to specify any other form of collection in PROV
15:47:58 [TomDN]
GK: Any kind of collection/dictionary
