Providing Provenance Information

[KathiSchleidt]

When exploring options for data provenance provision, I recently came across an interesting new activity under OGC integrating the concepts from the W3C PROV-O Provenance Ontology within a STAC provenance extension. As this is one of the bits where we'd need to propose something to STAC anyway, I'd prefer to utilize this approach (PROV-O has long been respected within the scientific community)

Input Term	multiplicity	Notes	currently implemented STAC name	PROV-O element	Comment KS
Origin	0...1	EO-based, produced by countries	stac:provenance_name		Think this may be a duplicate of Data Source, thus could be cut
Preprocessing	0...1	Description of the preprocessing	stac:preprocessing	missing	requested
Source Data	0...1	link to data	stac:source_data	prov:wasDerivedFrom
Models	0...1	A url link to the processing Model	stac:models	prov:wasGeneratedBy
Documents & Publications	1		stac:documentation	missing	requested

Note: the way PROV-O is designed, the concepts can link either directly to an external resource. I'd link to the STAC records for source data and a/p processing resources. See the first example for direct linking

@baloola have you made any progress in integrating the PROV-O STAC extension?
