It has been suggested that MODS include a date of access. The example
given was for bibliographic citations. The Chicago Manual of Style
includes an access date for an electronic resource (i.e. date it was last
accessed, since Web sites change frequently) in standard bibliographic
citations. This is different from dateModified, which is being added to
MODS in version 3.0, in that dateModified tells you date that the resource
was last changed, while date accessed would tell you when it was last
viewed or accessed and makes no claims about when it was last modified. In
addition to being able to accurately produce bibliographic citations, this
date might be useful for any resource that is updated regularly-- Web
sites, documents made available electronically, databases.
AACR2 cataloging generally includes this information in a general note for
Web sites. Since this is a date, a note does not seem an appropriate
solution (a note can still be input regardless).
The original suggestion was to add a type attribute to dateOther, but this
is not how we have handled dates in MODS. If a specific type of date, a
separate element is used. We wouldn't want to mix using a type attribute
and a separate named element. Are there any thoughts about adding another
date to MODS? Under <originInfo> it would be <dateAccessed>. It then would
use the dateType definitions.
