PROV-ISSUE-207 (start and end records): start and end records [prov-dm] http://www.w3.org/2011/prov/track/issues/207 Raised by: Luc Moreau On product: prov-dm We have recently voted on definitions for generation and usage records. Start and end records are the corresponding 'instantaneous events' for activities. We should therefore define start/end records as representation of activity start/end events. Second, time is handled differently for entities and activities. The placeholders for time information related to entities is in generation and usage events. But for activities, it's in the activity record. Shouldn't activity start/end time be moved to start/end record? If we do move activity start/end time to start/end record, then shouldn't we also make the agent optional, for cases where we want to assert time without knowing the agent. This latter proposal may also have implications for the prov-o ontology.
