(Click image for full size graphic.) Following the JISC seminar last week on persistent identifiers (#jiscpid on Twitter) there was some discussion about DOI and its role within a Linked Data context.

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 &

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.

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. Tattoo them on your pets.

[See this link if you’re short on time: facets search client. Only tested on Firefox at this point. Caveat: At time of writing the Crossref Metadata Search was being very slow but was still functional.

Following on from my recent post about our shiny new nature.com OpenSearch service we just put up a cheatsheet for users. I’m posting about this here as this may also be of interest especially to those exploring how SRU and OpenSearch intersect. The cheatsheet can be downloaded from our nature.com OpenSearch test page and is available in two forms: Cheatsheet (PDF, 65K) Cheatsheet (PNG, 141K) Naurally, all comments welcome.

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.

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.

(Click panels in figure to read related posts.) Following up on my earlier posts here about the structured search technologies OpenSearch and SRU, I wanted to reference three recent posts on our web publishing blog Nascent which discuss our new nature.com OpenSearch service: 1. Service Describes the new nature.com OpenSearch service which provides a structured resource discovery facility for content hosted on nature.com. 2.

Crossref Technical Meeting* The Charles Hotel, Cambridge, MA Monday, November 9th, 2009 2:00 pm - 5:00 pm Please register today! We also encourage you to register for our 10th Anniversary Celebration Dinner, which will take place Monday, November 9th, 2009 at 6:30 pm following the Crossref Technical Meeting at the Museum of Science in Boston, MA.

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.
