Carl,

Thanks very much.  As we move to more continuous auth that uses multiple attributes, this will become more important.

TC may wish to consider whether this W3C model could become a normative reference and possibly formulate a group reply as feedback.

two extracts of note ... 

21.3 Agents and Responsibility

For many purposes, a key consideration for deciding whether something is reliable and/or trustworthy is knowing who or what was reponsible for its production. Data published by a respected independent organization may be considered more trustworthy than that from a lobby organization; a claim by a well-known scientist with an established track record may be more believed than a claim by a new student; a calculation performed by an established software library may be more reliable than by a one-off program.

An agent is something that bears some form of responsibility for an activity taking place, for the existence of an entity, or for another agent's activity

2.2.2 Provenance of Provenance

A bundle is a named set of provenance descriptions, and is itself an entity, so allowing provenance of provenance to be expressed.

For users to decide whether they can place their trust in something, they may want to analyze its provenance, but also determine the agent its provenance is attributed to, and when it was generated. In other words, users need to be able to determine the provenance of provenance. Hence, provenance is also regarded as an entity (of type Bundle), by which provenance of provenance can then be expressed.

Hi All,

The W3C Provenance Working Group [1] is excited to announce Last Call
on 3 documents that define the core of the PROV family of
specifications. These 3 documents focus on how to model provenance
information for the purposes of interchange.

- PROV-DM is a data model for provenance interchange
- PROV-O is an OWL2 ontology mapping of PROV-DM to RDF
- PROV-N is a notation for provenance aimed at human consumption

In addition to these Last Call Working Drafts, we are also releasing
an updated Primer that is synchronized with these specifications.

You'll find a quick overview and links to the documents at:

http://www.w3.org/blog/SW/2012/07/24/last-call-3-working-drafts-for-provenance-interchange/

We're really looking for your feedback, comments go to
public-prov-comments@w3.org and we hope to have them by 18 September
2012.

Thanks
Paul
