NTS:: Metadata sources

More sources of article metadata:

citeulike
This data is useful because it groups related ids for each "view" of a resource (e.g. PMID & DOI for the same article). "
Article linkout data Mapping CiteULike article_ids to resources on the web can be done with the linkout table.
"The current snapshot is available at http://static.citeulike.org/data/linkouts.bz2 Data is available from 2008-02-02 onwards."
"To understand the data in this file, you should refer to "The linkout formatter" section of the plugin developer's guide. This file contains a number of spam links. Although CiteULike filters spam postings, traces of the spam still remain in this table. In time this spam content will eventually be removed. The file is a simple unix ("\n" line endings) text file with pipe ("|") delimiters. Literal pipes within the fields are represented escaped ("\|"). The columns are: 1. Article Id 2. Linkout type 3. ikey_1 4. ckey_1 5. ikey_2 6. ckey_2
NB If an article has n linkouts, then this will result in n rows in the file."

150mb download, but most likely worth it

NZETC (New Zealand Electronic Text Center)
Some solid work, indexed by Index New Zealand, so can use Z39.50 to grab the data from INNZ. I'd like to see what can be done with the TEI-XML too.

NCBI
Worth listing for the version 2 of their wonderful web services.

NTS:: RDA (Important Library Stuff)

Hmmm... it did look like RDA might be the sort of thing I was wanting... supposed to have the granularity I'd like, but just seeing the draft documents makes me just balk.

Once you download the zip file, and see the size of the pdfs, you realise how much work has been done, (a lot), but also how much work is involved in implementing it. Not being a cataloguer, getting my head around this would take too long, so I'm probably going to soften it, and go with something similar, but easier.

My grand plan, (which is all it is at this stage - whether it gets to be anything more is dubious), would be a central repository for the tags, and how they translate... whether this would be a networked thing remains to be seen.
