MARC Authority 001 and Linked Data (was RE: Linked Data URIs in MARC Authorities)

VIAF is using Corine's suggestion of the MARC Authority 024 to record the URI that identifies "the entity named in the 1XX field" (aka "real world object" or "non-information resource").

024 7# $ahttp://viaf.org/viaf/102333412‏$2uri‏


Contrast that with the URI VIAF coins specifically for the corresponding MARC21 representation (aka " document" or "information resource"):

http://viaf.org/viaf/102333412/marc21.xml 

I would argue that this URI is the de facto "control number" for our MARC21 Authority record and thus belongs in the 001 field. Here's the spec:

http://www.loc.gov/marc/authority/ad001.html


Here's what it would look like in context:

001 http://viaf.org/viaf/102333412/marc21.xml

003 OCoLC
024 7# $ahttp://viaf.org/viaf/102333412‏$2uri‏


Does anyone disagree with this interpretation or imagine a plausible scenario where using an HTTP URI in the 001 would cause problems?
