Describe creation and stewardship of a scientific data product.
class pycsamt.metadata.provenance.ProvenanceMeta(create_time=None, creating_application=None, creator=None, submitter=None, extra=<factory>)[source]

Bases: PyCSAMTObject

Describe creation and stewardship of a scientific data product.

This object is deliberately independent of EDI and XML syntax. It maps naturally to EMTF provenance fields while remaining reusable by future formats and airborne data products.

Parameters:

  • create_time (datetime or str, optional) – Product creation time. Strings are preserved verbatim so historical metadata can be retained without inventing a timezone or precision.

  • creating_application (str, optional) – Application that created the data product.

  • creator (Person, optional) – Original creator and person responsible for submission/archiving.

  • submitter (Person, optional) – Original creator and person responsible for submission/archiving.

  • extra (dict) – Unmodelled provenance fields retained losslessly in memory.

create_time: datetime | str | None = None
creating_application: str | None = None
creator: Person | None = None
submitter: Person | None = None
extra: dict[str, Any]
validate()[source]

Validate object state.

Subclasses can override this hook. The base implementation intentionally accepts all states.

Return type:

None
