Hi, Priscilla:
What we're starting to do is put in the date at which either a formal
agreement or informal decision is made (could be the date of ingestion of
the object into the repository even), and then 9999 as the end date. I'm
almost certain, (but not checking) that ISO 8601 will allow yyyy only, and
of course the begin date would be following the ISO 8601 expectation.

Subject: [PIG] dates for rights
In (rights) permissionStatement.termOfGrant the start and end date of
the permission granted is required and ISO 8601 format is recommended.
But what if something has no real start (e.g. fair use) or no end
(e.g. perpetual)?
Seems like you wouldn't want to say "none" because that wouldn't pass
parsing. Perhaps you could use "0000" for no start date and "9999" for
no end date -- this seems to be what is done in the PREMIS examples.
Is there a standard convention that people use?
