Recently we announced that we were making some new recommendations in our DOI display guidelines. One of them was to use the secure HTTPS protocol to link Crossref DOIs, instead of the insecure HTTP.

DataCite supporting content negotiation

In April In April for its DOIs. At the time I cheekily called-out DataCite to start supporting content negotiation as well. Edward Zukowski (DataCite’s resident propellor-head) took up the challenge with gusto and, as of September 22nd DataCite has also been supporting content negotiation for its DOIs. This means that one million more DOIs are now linked-data friendly. Congratulations to Ed and the rest of the team at DataCite. We hope this is a trend.

Content Negotiation for Crossref DOIs

So does anybody remember the posting DOIs and Linked Data: Some Concrete Proposals? Well, we went with option “D.” From now on, DOIs, expressed as HTTP URIs, can be used with content-negotiation. Let’s get straight to the point. If you have curl installed, you can start playing with content-negotiation and Crossref DOIs right away: curl -D - -L -H “Accept: application/rdf+xml” “”  curl -D - -L -H “Accept: text/turtle” “http://dx.

OpenSearch/SRU Integration Paper

Since I’ve already blogged about this a number of times before here, I thought I ought to include a link to a fuller writeup in this month’s D-Lib Magazine of our OpenSearch service which serves as a case study in OpenSearch and SRU integration: doi:10.1045/july2010-hammond

With PDF now passed over to ISO as keeper of the format (as blogged here on CrossTech), Kas Thomas (on CMS Watch’s TrendWatch) blogs here that Adobe should now do the right thing by XMP and look to hand that over too in order to establish it as a truly open standard. As he says: “Let’s cut to the chase. If Adobe wants to demonstrate its commitment to openness, it should do for XMP what it has already done for PDF: Put it in the hands of a legitimate standards body.

Word Add-in for Scholarly Authoring and Publishing

Last week Pablo Fernicola sent me email announcing that Microsoft have finally released a beta of their Word plugin for marking-up manuscripts with the NLM DTD. I say “finally” because we’ve know this was on the way and have been pretty excited to see it. We once even hoped that MS might be able to show the plug-in at the ALPSP session on the NLM DTD, but we couldn’t quite manage it.

On March 3rd the Open Archives Initiative held a roll out meeting of the first alpha release of the ORE specification ( . According to Herbert Van de Sompel a beta release is planned for late March / early April and a 1.0 release targeted for September. The presentations focused on the aggregation concepts behind ORE and described an ATOM based implementation. ORE is the second project from the OAI but unlike its sibling PMH it is not exclusively a repository technology.

Well, Howard already blogged on Nascent last week about the STIX fonts (Scientific and Technical Information Exchange) being launched and now freely available in beta. And today the STM Association also have blogged this milestone mark. So, just for the record, I’m noting here on CrossTech those links for easy retrieval. As Howard says: “I recommend all publishers download the fonts from the STIX web site at today.”

There’s a great exposition of FRBR (the Functional Requirements for Bibliographic Records model “work -> expression -> manifestation -> item“) in this post from The FRBR Blog on De Revolutionibus as described in The Book Nobody Read: Chasing the Revolutions of Nicolaus Copernicus by Owen Gingerich. See post for the background and here (103 KB PNG) for a map of the FRBR relationships. (Yes, and a twinkly star in the title too.
