Re: Wikidata now has a "refine date" property

Another approach to specifying inexact dates is available through the
Library of Congress's Extended Date/Time Format ED/TF, which handles cases
not accommodated by ISO 8601-2004.  (See )

The functionality of ED/TF is being incorporated into a revision of ISO
8601 that's currently under ratification.  (See After
ratification, expect will allow more fuzzy dates, such as when
the beginning or end date is not know for certain.
