Cf. http://www.w3.org/2011/prov/track/issues/596 At the face-to-face meeting we agreed that detailed treatment of bundles is out of scope for PROV-AQ, which deals specifically with provenance descriptions associated with resources. But in later discussion, Paul raised the question of whether we should say *anything* about what happens on dereferencing a bundle URI. It's possible that sentence about this would not be out of order in section 1.4 (http://dvcs.w3.org/hg/prov/raw-file/tip/paq/prov-aq.html#uri-types-and-dereferencing). I'm thinking that something along the following lines might be helpful to some: [[ The notion of provenance bundles for a named set of provenance descriptions is introduced in [PROV-DM] (section 5.4.1 - http://dvcs.w3.org/hg/prov/raw-file/tip/paq/prov-aq.html#uri-types-and-dereferencing). This specification is mainly concerned with accessing the provenance descriptions associated with entities, without regard to the bundles in which they occur. But bundles too may be retrievable entities. Given a URI for a bundle, dereferencing that URI should yield a representation of the bundle; this might be a PROV-N document [[PROV-N]], a serialization of an RDF dataset [[RDF1.1-concepts]] (https://dvcs.w3.org/hg/rdf/raw-file/default/rdf-concepts/index.html#section-dataset) or some other representation that collects several named provenance descriptions into a single entity. ]] What this does not say is how to locate a named provenance description within a bundle. Without being far more specific about the format of a bundle representation, which I claim is out of scope for PROV-AQ, I don't think that is possible here. #g -- Tracker, this is ISSUE 596
