(Update - 2007.07.28: I meant to reference in this entry Pierre Lindenbaum’s post back in May Is there any XMP in scientific pdf ? (No), which btw also references Roderic Page’s post on XMP but forgot to add in the links in my haste to scoot off. Well, truth is we still can’t answer Pierre in the affirmative but at least we can take the first steps towards rectifying this.)
I wanted to share some of my early experiences. First off, after a couple of previous attempts which got pushed aside due to other projects, I managed to compile the libraries and the sample apps that ship with the C++ SDK under Xcode on the Mac. I also needed to compile Expat first which doesn’t ship with the distribution.
OK, so far, so good. What this basically leaves one with is a couple of XMP dump utilities (DumpMainXMP and DumpScannedXMP) and two others (XMPCoreCoverage and XMPFilesCoverage) which is a good start anyways for exploring. And turns out that our PDFs already have some workflow metadata in them. This is encouraging because the SDK allows apps to read and update existing XMP packets from files, though not to write new packets into files (as far as I understand).
I thought I would take this opportunity anyway to:
Try and add these to existing XMP packetsUgly details are presented below, but by updating the XMP packet metadata in one of our PDFs (Nature 445, 37 (2007), C.J. Hogan) we can teach Acrobat Reader to read - see the “before” (PDF here) and “after” (PDF here) screenshots in the figure.
Of course, this is really about much more than getting Adobe apps to read/write metadata. It’s about using XMP as a standard platform for embedding metadata in digital assets for third-party apps to read/write. If we can put ID3 tags into our podcasts then why not XMP packets into other media?

We updated our Project Prospect articles today to release v1.1, with a pile of look & feel improvements to the HTML views and links. The most interesting technical addition is the launch of our enhanced RSS feeds, where we have updated our existing feeds for enhanced articles. These now include ontology terms and primary compounds both visually (as text terms and 2D images) and within the RDF - using the OBO in OWL representation and the info:inchi specification mentioned here by Tony only a few weeks ago.
The enhanced entries will soon become more common as we concentrate our enhancements on our Advance Articles, but the current example below from our Photochemical and Photobiological Sciences feed is lovely. RDF code after the jump - just as beautiful to the parents…
