1. Add an xlink attribute to <physicalLocation>. It seems that we need an
xlink attribute to be used with <physicalLocation> (under location). This
is equivalent to $u in MARC field 852. That is, the URL for a website for
the institution named in physicalLocation. This is not the same as
<location><url>, which is the URL for the resource described in the
record. Such an element is also included in the proposed ISO holdings
schema. Using xlink would be consistent with other places in MODS where
we make such a link (similar to $u in MARC fields).
2. Add another enumerated value for authority under <language>.
ISO 639-3 was recently approved and codes all known individual
languages. This list is much more granular than the ISO 639-2 list.
FYI: we can handle this in MARC 041 field by adding it to the list of
authorities defined for use with subfield $2. In MODS we have these
enumerated in the schema, although in a later version we may want to
change that to make it more extensible.
In addition, RFC3066 has been superceded by RFC4646, so we may want to
add that too. I would leave RFC3066 for earlier records.
Are there any objections to either of these changes to be included in
version 3.3?
