I don't quite understand the need for the suggested granularity attribute. In your example, you would supply a date/time value of 2007-02-01T00:00:00Z And include a granularity attribute, YYYY-MM, to indicate that only 2007-02 is significant. But then why supply the whole value? Why not just supply 2007-02? All of the formats - w3cdtf, iso8601, and marc -- allow this. --Ray ----- Original Message ----- From: "Christiaan Kortekaas" <[log in to unmask]> To: <[log in to unmask]> Sent: Monday, April 23, 2007 10:17 PM Subject: Re: [MODS] MODS 3.3 draft ready for review Hi Sally Have you considered adding a date granularity attribute to any element in MODS that will express a date value? I queried the MODS mailing list about this in my email on the 19/1/2007 but have had no reply.
