Quoting "Young,Jeff (OR)" <jyoung@oclc.org>: > > 024 8# $u http://example.org/foo > > I would argue that the spec for this new $u should be explicitly > worded to mention "Linked Data".

It could be used for anything where an identifier is useful -- not just linked data. Or are you thinking of this subfield to be *only* for LD identifiers? In that case, it might be useful to use a subfield other than $u, which in MARC has usually been used for URLs, not URIs (the 856 is specifically a location area field). So 035 $l or 035 $i, or something like that. kc > > Jeff > >> -----Original Message----- >> From: rxs@talisplatform.com [mailto:rxs@talisplatform.com] On Behalf Of >> Ross Singer >> Sent: Friday, October 01, 2010 4:36 PM >> To: Martin Malmsten >> Cc: Young,Jeff (OR); public-lld >> Subject: Re: Linked Data URIs in MARC Authorities >> >> Martin, I think it's a fine proposal. >> >> The only possible downside I can see (as opposed to using, say, the >> 035, for example) is that it would be in a different location >> depending on the kind of authority record it is >> (personal/corporate/meeting name, uniform title, topical, >> geographical, etc.). >> >> That's not necessarily a killer, but it would mean you'd need to look >> for every field until you found the URI.
