What is the correct way to say "this association was last updated from the source on {date}"?

Question:
What is the correct way to say "this association was last updated from the source on {date}"?

I would like to be able to tag an edge in a KGX file with something like "date: 2024-01-01" or better "updated: 2024-01-01", when the association behind the edge was extracted from a source on that day.

I looked into

biolink-model/biolink-model.yaml

Line 825 in fe44b8d

update date:

but it seems this only goes for nodes. And its also a bit ambiguous (but would do, I guess, if it was common practice).

@kevinschaper suggested

definitely looks like an ambiguity that we should fix in the model, plus it isn't actually associated with any classes yet. We could make a PR to take of the node property is_a, improve the definition (I can't tell whether an ingest that loads from another source should update it based on when that load happens, or only pull the date from the original source, I assume original source?) and associated it with the Entity class

@sierra-moxon what do you think? Is there a better way?
