1 Definition
A Data Type containing an ordered list of Events representing lifecycle-relevant information about an Asset. Each Event in the Provenance corresponds to an operation that has affected the Asset or one of its successive representations.
A Provenance Item may include references to information associated with these Events (e.g., identifiers of Items involved, identifiers of Services producing them, and optional references to descriptive or justificatory entries).
2 Functional Requirements
The Provenance Data Type shall:
– contain an ordered list of Events describing relevant changes associated with the Asset;
– allow inclusion of multiple types of Events beyond Transactions (e.g., creation, modification, conversion, transfer), provided they are directly linked to the Asset and its successive Items;
– provide optional support for attaching descriptive or justificatory metadata to Events when needed.
