The Link header allows the specification of an anchor that provides the context for the relationship [1]. This is used state what the relationship is associated with. So may be possible to specify the BOB-identifier as part of that. By default, when the anchor is omitted, the link refers to the current document. e.g. Link: provenance-URI; rel="provenance"; anchor="bob-uri" This has the added advantage of returning the provenance URIs for multiple documents in the same HTTP response. While HTML4's link tag [2] is semantically equivalent to the HTTP Link header [3], it is not clear what the corresponding attribute for 'anchor' is in HTML. --Yogesh [1] http://tools.ietf.org/html/rfc5988#section-5.2 [2] http://www.w3.org/TR/html4/struct/links.html#h-12.3 [3] http://tools.ietf.org/html/rfc5988#appendix-A | -----Original Message----- | From: public-prov-wg-request@w3.org [mailto:public-prov-wg-request@w3.org] | On Behalf Of Provenance Working Group Issue Tracker | Sent: Monday, July 25, 2011 2:03 AM | To: public-prov-wg@w3.org | Subject: PROV-ISSUE-47 (third-party-provenance): How to obtain provenance from | a third party known by the user [Accessing and Querying Provenance] | | | PROV-ISSUE-47 (third-party-provenance): How to obtain provenance from a third | party known by the user [Accessing and Querying Provenance] | | http://www.w3.org/2011/prov/track/issues/47 | | Raised by: Luc Moreau | On product: Accessing and Querying Provenance | | I don't understand how the proposal allows us to address | http://www.w3.org/2011/prov/wiki/ProvenanceAccessScenario. | | Specifically, I consider the case where the user wants to access provenance from a | third-party they know (e.g. a favorite consumer group). | | Using section 3, I can obtain one or more provenance-uris, which are known from | the responding server or the document creator. | | If my third-party is not known by the responding server or document creator, I have | no mechanism to obtain a provenance-uri since I don't have have an identifier for | the document I currently hold. | | A solution could be: we need a BOB-identifier to be passed around (as suggested in | ISSUE-46) and a mechanism that resolves a BOB-identifier to provenance-uri. | |
