- paulo, isn't there an outline of specification in http://www.w3.org/2011/rdf-wg/wiki/TF-Graphs/RDF-Datasets-Proposal?
- 15:17:26 [pgroth]
- paulo: in terms of formal specification, they are moving targets, even if they have one, we need more than one for the provenance solution
- 15:17:50 [pgroth]
- paulo: the fact that we want to work with named graphs are just one of the aspects of formalizing provenance
- 15:18:03 [khalidbelhajjame]
- One of the concepts we may need RDF graph for is Provenance Container. We have not really discussed this concept in details yet, though.

- q?
- 15:19:20 [pgroth]
- pgroth: shaping where the rdf-wg is going on named graphs
- 15:19:50 [pgroth]
- paulo: assumption is that the mapping to owl, and rdf is enough in terms of formalization
- 15:20:11 [Luc]
- q?
- 15:20:16 [pgroth]
- paulo: not enough for the formalization
- 15:20:52 [khalidbelhajjame]
- Paulo, we are investigating in the formal model task force on whether OWL is sifficient, or whether we need another language that we need to specify the semantics
- 15:21:05 [pgroth]
- luc: simon identified two requirements for named graphs, there's a third requirement coming from the provenance container (have asserter, maybe having signature)
- 15:21:18 [pgroth]
- luc: a possibility for provenance containers is to use named graphs
- 15:21:20 [Luc]
- q?
- 15:21:35 [pgroth]
- luc: potentially another requirement for the rdf wg
- 15:21:47 [pgroth]

- MacTed: i'm not getting a firm understanding of what is meant by the proposal
- 15:41:01 [pgroth]
- Luc: explaining an example
- 15:41:58 [khalidbelhajjame]
- Mac, he possibilities we are discussing are: entity <--uses---process execution and entity ---is used by --> process execution. In the first, the edges point to the past.
- 15:42:24 [pgroth]
- MacTed: there are two time frames, saying both of those is useful
- 15:42:38 [jorn]
- Luc's example: process generates output vs. output is generated by process
- 15:42:42 [pgroth]
- luc: only one of them is defined in the model
- 15:42:44 [smiles]
- I think the case for future-to-past directionality (as proposed) is clearest where provenance is distributed. If I have created a new entity, for example, then what I can link it to is other entities which already exist, but not to things which don't yet exist. So the new entity is the *subject* of what I'm asserting, the older entity is the *object*.
- 15:42:59 [pgroth]
- Luc: useful to have a convention
- 15:43:19 [pgroth]
- MacTed: this is a question for reasoning edges to deal with their inverse
- 15:44:10 [pgroth]
- MacTed: inverse properties are extremely important for modeling

- As part of the formal model discussion, we are enumerating the list of possible properties - I invite Ted to add his proposal to the ontology wiki: http://www.w3.org/2011/prov/wiki/PIL_OWL_Ontology
- 15:46:54 [Luc]
- why not define them as "short-cut/extensions"
- 15:48:10 [pgroth]

- 15:51:19 [Luc]
- q?
- 15:51:20 [pgroth]
- jorn: maybe problematic because you would always have to turn on reasoning
- 15:51:38 [pgroth]
- MacTed: definitely not a should
- 15:52:53 [pgroth]
