Public comment period on the PRISM 2.0 draft ends Saturday (Sept. 15) ahead of next week’s WG meeting to review feedback and finalize the spec. (I put in some comments about XMP already.

(Update - 2007.09.15: Clean forgot to add in the rdf: namespace to the examples for xmp:Identifier in this post. I’ve now added in that namespace to the markup fragments listed.

You might have been wondering why I’ve been banging on about XMP here. Why the emphasis on one vendor technology on a blog focussed on an industry linking solution? Well, this post is an attempt to answer that.

Following on from the missing XMP Specification version number discussed in the previous post here below are listed some miscellaneous gripes I’ve got with XMP (on what otherwise is a very promising technology). I would be more than happy to be proved wrong on any of these points.

David Shorthouse and Rod Page have developed some great tools for linking references by tying together a number of services and using the Crossref OpenURL interface amongst other things.

Boy, was I ever so wrong! Contrary to what I said in yesterday’s post, the new PRISM 2.0 spec does support XMP value type mappings for its terms. See the table below which lists the PRISM basic vocabulary terms and the XMP value types.

Following on from yesterday’s post I just came across this very useful source of information on PDF/A: the PDF/A Conformance Center.

So, following up on my recent posts here on Metadata in PDFs (Strategies, Use Cases, Deployment), I finally came across PDF/A and PDF/X, two ISO standardized subsets of PDF. the former (ISO 19005-1:2005) for archiving and the latter (ISO 15929:2002, ISO 15930-1:2001, etc.) for prepress digital data exchange.

From Ray Denenberg’s post to the SRU Listserv yesterday: Interested to learn if any Crossref publishers are currently implementing SRU.

So, assuming we know the form of the metadata we wish to add to our PDFs (or else to comply with if there is already a set of guidelines, or some industry initiative in effect) how can we realize this?

Only just caught up with this but the PRISM 2.0 draft is now available (since July 12) for public comment. See this posted by Dianne Kennedy: _“Just a note to let you know that PRISM 2.0 has just been posted at www.prismstandard.org . This is the first major revision to PRISM.
