In order to create a meaningful history, the individual provenance records used must retain their intended meaning when interpreted in a context other than that in which they were collected.
           Yet, we may still want to make provenance assertions about dynamic or context-dependent resources (e.g. a weather forecast for London on a particular day may have been derived from a particular set of Meteorological Office data).

           A provenance record consumer will need to isolate information about the specific entity or entities of interest.  These may be <a class="internalDFN">constrained resource</a>s identified by separate target-URIs that differ from the resource URI, in which case the consumer needs to discover those target-URIs. The mechanisms defined later allow a provider to expose such URIs.
