PROV-ISSUE-165 (TLebo): Enforcing non-contradictory provenance. [Accessing and Querying Provenance] http://www.w3.org/2011/prov/track/issues/165 Raised by: Timothy Lebo On product: Accessing and Querying Provenance http://dvcs.w3.org/hg/prov/raw-file/default/paq/provenance-access.html 2. Accessing provenance information "... the availability of provenance information about a resource may vary ... provided that such change does not contradict any previously retrieved information." I could imagine a service that reports the creation date of a file, but "forgot" to handle a daylight savings transition and reported a time that is incorrect by one hour. Once this bug was identified and corrected, must an entirely NEW provenance URI be used to offer the corrected provenance information? According to the "non-contradictory" requirement stated in PAQ, one could not just tweak the true modification time and offer it at the original provenance URI. Is this the desired intent? Thanks, Tim
