Hi Malcolm,

Hm, if the date of deposit denotes the creation of the archival copy,
<dateCreated> might work, but only because this is a digital archive so
acquiring a resource is the same as creating a copy.  In general, what
you're talking about sounds like holdings metadata, for which there are
other XML schemata.  In MODS, you'd put the elements from that schema in
<extension>; if you change <originInfo>, you aren't using MODS anymore!
If interoperability is not a concern, though, just write your own XML
schema that imports the standard MODS schema and then redefines the
content model of <originInfo>.

Hello,

Could somebody advise me please? The AHDS is a digital archive and we
would
like to record the 'date of deposit' in addition to the standard
date-related subelements of MODS (date issued, created, captured,
valid, and
modified). Could this be done by qualifying <originInfo> by the use of
a
local subelement such as <ahds:dateDeposited>?

e.g. <mods:originInfo>
<mods:dateCreated></mods:dateCreated>
<ahds:dateDeposited></ahds:dateDeposited>
</mods:originInfo>

or would I have to use <extension>?

e.g. <mods:extension><ahds:dateDeposited>

 - the latter would seem rather clunky in that 'date of deposit' is
clearly
date-related and therefore concerns the same basic concept as the
existing
date-related subelements of <originInfo>.

There are quite a few MODS elements that we would like to refine
locally but
but the user guidelines seem to me to only offer a mechanism for
introducing
completely new elements. Are local subelements permissible and is there
a
recommended approach? Similarly, can one introduce local attributes?

Any help would be appreciated. We're at the stage of considering
whether to
use MODS.

Thanks in advance,

Malcolm Polfreman
