Hi Luc,
Trust is not provenance as we agreed in the provenance incubator group. Is
trust associated with the record or the asserter who created the record or
the elements being described in the record? I am not sure trust or
reputation was in the scope of this WG?

Similarly, I am not sure why should rendering information (all examples of
dotted, doc.png in the DM) for provenance records be part of our work to
facilitate provenance interchange? This can be easily extended to state
that provenance records should be viewed using Firefox or Chrome and using
color monitors and over internet speeds of 10Mbps, and so on - this seems
to be completely out of scope for the WG.

The only place for adding notes and the associated "meta" information seems
to be best practices document.

Best,
Satya
