Was outraged (outraged, I tell you) that one of my favorite online comics, PhD, didn’t include DOIs in their recent bibliography of Christmas-related citations.. So I’ve compiled them below. We care about these things so that you don’t have to. Bet you will sleep better at night knowing this. Or perhaps not… A Christmas Reading List… with DOIs. Citation: Biggs, R, Douglas, A, Macfarlane, R, Dacie, J, Pitney, W, Merskey, C � O’Brien, J, 1952, ‘Christmas Disease’, BMJ, vol.

Add Crossref metadata to PDFs using XMP

In MetadataPDFXMP

In order to encourage publishers and other content producers to embed metadata into their PDFs, we have released an experimental tool called “pdfmark”, This open source tool allows you to add XMP metadata to a PDF. What’s really cool, is that if you give the tool a Crossref DOI, it will lookup the metadata in Crossref and then apply said metadata to the PDF. More detail can be found on the pdfmark page on the Crossref Labs site.

QR Codes and DOIs

Inspired by Google’s recent promotion of QR Codes, I thought it might be fun to experiment with encoding a Crossref DOI and a bit of metadata into one of the critters. I’ve put a short write-up of the experiment on the Crossref Labs site, which includes a demonstration of how you can generate a QR Code for any given Crossref DOI. Put them on postcards and send them to your friends for the holidays.

Recommendations on RSS Feeds for Scholarly Publishers

We’re pleased to announce that a Crossref working group has released a set of best practice recommendations for scholarly publishers producing RSS feeds. Variations in practice amongst publisher feeds can be irritating for end-users, but they can be insurmountable for automated processes. RSS feeds are increasingly being consumed by knowledge discovery and data mining services. In these cases, variations in date formats, the practice of lumping all authors together in one dc:creator element, or generating invalid XML can render the RSS feed useless to the service accessing it.

The other day Noel O’Boyle wrote to tell me that he had updated the Ubiquity plug-in that we had developed in order to to make it work with the latest version of Firefox. The problem was, I had *also* updated the Ubiquity plug-in, but I hadn’t really indicated to anybody how they could find updates to the plug-in. /me=embarrassed. So it seemed time to provide a home for some of the prototypes and experiments that we’ve been developing at Crossref.

PRC Report and “iPub” revisited

Geoffrey Bilder

Geoffrey Bilder – 2009 September 07

In IPub

OK, so this has nothing to do with any Crossref projects- but there is an interesting new PRC report out by Mark Ware in which he explores how SMEs (small/medium-sized enterprises) make use of scholarly articles and whether the scholarly publishing industry is doing anything to make their lives easier. This is a topic that is close to my heart. For the past few years I’ve been saying (most recently at SSP09) that I think scholarly publishers are much too quick to dismiss the possibility of creating an iTunes-like service for scholarly publications (aka “iPub”).

Strategic Reading

Allen Renear and Carole Palmer have just published an article titled “Strategic Reading, Ontologies, and the Future of Scientific Publishing” in the current issue of Science ( I’m particularly happy to see this paper published because I actually got to witness the genesis of these ideas in my living room back in 2006. Since then, Allen and Carole’s ideas have profoundly influenced my thinking on the application of technology to scholarly communication.

OCLC defines requirements for a “Cooperative Identities Hub”

Geoffrey Bilder

Geoffrey Bilder – 2009 May 01


OCLC has published a report (PDF) identifying some requirements for what they call a “Cooperative Identities Hub”. A quick glance through it seems to show that the use cases focus on what we are calling the “Knowledge Discovery” use cases. As I mentioned in my interview with Martin Fenner, there is also a category of “authentication” use cases that I think needs to be addressed by a contributor identifier system. Still, this is a good report that highlights many of the complexities that an identifier system needs to address.

What do people want from an author identifier?

Geoffrey Bilder

Geoffrey Bilder – 2009 April 27


Martin Fenner continues his interest in the subject of author identifiers. He recently posted an online poll asking people some specific questions about how they would like to see an author identifier implemented.* The results of the poll are in and, though the sample was very small, the results are interesting. The responses are both gratifying -there seems to be a general belief that Crossref has a roll to play here- and perplexing -most think the identifier needs to identify other “contributors” to the scholarly communications process- yet there seems to be a preference for the moniker “digital author identifier”.
