This is not a post I'd thought I'd write, because OpenURL is an awful spec. But last week I ended up in vigorous debate on Twitter after I posted what I thought was a casual remark: This ended up being a marathon thread about OpenURL, accessibility, bibliographic metadata, and more.

Following on from my previous post bemoaning the lack of links between biodiversity data sets, it's worth looking at different ways we can build these links. Specifically, data can be tightly or loosely coupled. Tight coupling Tight coupling uses identifiers. A good example is bibliographic citation, where we state that one reference cites another by linking DOIs.

Mendeley has added a feature which makes it easier to use Mendeley with repositories such as BioStor and BHL.

Yesterday I posted notes on Web Hooks and OpenURL. That post was written when I was already late (you know, when you say to yourself "yeah, I've got time, it'll just take 5 minutes to finish this..."). The Web Hooks + OpenURL project is still very much a work in progress, but I thought a screen cast would help explain why I think this is going to make my life a lot easier.

For me one of the most frustrating things about online databases is that they often can't be edited. For example, I've recently created a version of the Australian Faunal Directory on CouchDB, which contains a list of all animals in Australia, and a fairly comprehensive bibliography of taxonomic publication on those animals. What I'd like to do is locate those publications online.

PLoS recently announced a dedicated iPad app, that covers all the PLoS Journals, and which is available from the App Store. Given the statement that "PLoS is committed to continue pushing the boundaries of scientific communication" I was expecting something special.

Today I finally got a project out the door. BioStor is my take on what an interface to theBiodiversity Heritage Library (BHL) could look like. It features the visualisations I've mentioned in earlier posts, such as Google maps based on extracted localities, and tag trees. It also has a modified version of my earlier BHL viewer.

After some fussing and hair pulling I've constructed a demo of linking a journal to the Biodiversity Heritage Library and displaying the results in Zotero (see my earlier post for rationale). After some searching I managed to retrieve metadata for several hundred article from the Bulletin of Zoological Nomenclature . Using a local copy of the BHL metadata, I wrote a script that looked up each article in BHL and found the URL of the

One thing I find myself doing (probably more often than I should) is adding a reference to my Zotero library for an item in the Biodiversity Heritage Library (BHL). BHL doesn't have article-level metadata (see But where are the articles?), so when I discover a page of interest (e.g., one that contains the original description of a taxon) I store metadata for the article containing that page in my Zotero library.

The LSID discussion rumbles on (see my earlier post). One issue that has re-emerged is the use of HTTP proxies in RDF documents.
