And since Terry just responded rather humbly, allow me to plug his MarcEdit:
http://marcedit.reeset.net/adding-localcustom-linked-data-resolution-to-marcedits-linked-data-tool
I was just looking into this reference as his email arrived.
Anyways - take a look at MarcEdit. I believe it is possible to match
these labels with URIs and insert them into MARC records. Terry, please
correct me if I am wrong.
Yours,
Kevin

The $0 is the correct field, but you would not link to this value:

and $1 are reserved for machine readable endpoints. They should *not* include
links to HTML pages.

Yes, I believe it is $0, but if you insert a URI you do not include a
parenthetical notation. See:
http://www.loc.gov/marc/bibliographic/ecbdcntf.html
All that said, best check with a cataloger.

best way to do that? My guess would be to store it in a 100 control
subfield 0, but I am not sure how to format it. Would it be something like this?
(lcname)http://id.loc.gov/authorities/names/n2010056162.html
I'm guessing there is some technical acronym I should use instead of
"lcname."

There's no reason to screen scrape the results.
The label service permits the use of the "Accept" header. For example:
curl -i -L -H "Accept: application/rdf+xml"
http://id.loc.gov/authorities/label/orchids
Take note of the initial set of response headers:
HTTP/1.1 302 FOUND
Location: http://id.loc.gov/authorities/subjects/sh85095334
X-URI: http://id.loc.gov/authorities/subjects/sh85095334
X-PrefLabel: Orchids
Cache-Control: public, max-age=1209600
Content-Length: 0

Connection: keep-alive
If you want, you could perform only a HEAD request on the label
service and then use the X-URI and X-PrefLabel headers to gather the
info you need. NB: The service works on an exact match, more or
less; take off the 's' of 'orchids' and you'll get an entirely different result.
You can also operate on the search results - not the label service -
programatically. See "Supported Search serialization formats" here:
http://id.loc.gov/techcenter/serializations.html One XML-based option
and a JSON one too.

Kevin

Thanks, Nathan. That looks like it will work if I do it manually,
but there is no interface for doing it programmatically. Is LC okay
with me screen scraping the search results?

You can try our "label" service. See under "known label retrieval" here:

I would be glad to help further.

Subject: [CODE4LIB] Searching LC Name Authority file
programmatically
I have sort of inherited authority control recently at my library,
and I want to find some way to automate some common workflows. I
am looking for an easy way to query blind name references against
the LC Name Authority master file. There is no API for searching
it on the web, and the name file itself is 10+ GB and hard to work
with.
Here are options as I see them:
- Screen scrape the search engine at id.loc.gov.
- Load the 10+ GB name file into a local database to query
programmatically.
Does anyone have experience with either method? Does some other
method exist I am not aware of?
