Subject: [MODS] Extended Date/Time format


Please excuse any duplication.

The Library of Congress, in conjunction with several partners, has initiated 
an effort to develop a simple  XML date/time format that can be referenced 
by XML schemas. In the MODS schema, for example, date formats are restricted 
to 'w3cdtf' (defined as the W3C Date Time Format Note which is a profile of 
ISO 8601), 'iso8601' (defined as the alternative in ISO 8601 "basic" that 
specifies the form YYYYMMDD, etc. rather than the form with hyphens), and 
'marc' (defined as the conventions used in the MARC 008/07-14 character 
positions).  None of these really meets the requirements of a date time 
format for these schemas.

Please see http://www.loc.gov/standards/datetime/  which provides a 
rationale for this work and the requirements that it addresses.  We  would 
be pleased to hear of additional requirements or any other comments or 
suggestions.   Please send comments to Ray Denenberg ([log in to unmask]) by April 
20, 2009.
