Discussion of the Extended Date/Time Format, EDTF, seems to have stabilized, and the features list has been turned into a draft specification.
We welcome comments, suggestion, corrections, omissions, etc., and there is still time to incorporate new requirements. Please post to the listserv.
The review period is November 5 to December 6.
We are examining options for moving the draft spec to formalization or standardization and suggestions are welcome. Possible candidate standards bodies are W3C and IETF.
