Proposed Definitions for the Concept 'Views or accounts'
Definition from Simon and Paul
An account is a record of something that has occurred from a particular perspective.
- Information regarding provenance is asserted by one or a group of sources and thus is an account of what has occurred.
- The provenance accessible for any one resource will, therefore, be composed of information from one or more accounts.
- The sources of accounts may not be identified.
- Every account should have an identifier, to ensure accounts can be distinguished and annotated.
- The same occurrence (e.g. a "resource" or "process execution") could be referred to in multiple accounts. It is a decision of the account sources whether they are referring to the same thing in their assertions.
- An example of perspective is the granularity of description: whether what has occurred is described coarsely or in detail. There may be other useful examples.
