Since last month’s threads (here, here, here and here) talking about the issues involved in making the DOI a first-class identifier for linked data applications, I’ve had the chance to actually sit down with some of the thread’s participants (Tony Hammond, Leigh Dodds, Norman Paskin) and we’ve been able sketch-out

(This post is just a repost of a comment to Geoff’s last entry made because it’s already rather long, because it contains one original thought - FRBR as OSI - and because, well, it didn’t really want to wait for moderation.) Hi Geoff: First off, there is no question but that Crossref

Tony’s recent thread on making DOIs play nicely in a linked data world has raised an issue I’ve meant to discuss here for some time- a lot of the thread is predicated on the idea that Crossref DOIs are applied at the abstract “work” level.

( Update - 2010.02.10: I just saw that I posted here on this same topic over a year ago. Oh well, I guess this is a perennial.) I am opening a new entry to pick up one point that John Erickson made in his last comment to the previous entry: Yea! It might be worth consulting the latest Crossref DOI Name Information and Guidelines to see what that has to say about this.

(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.

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.

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.

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.

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.
