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.

I've been buried in programming (and it's exam time at Glasgow) so I've not blogged for a month (gasp). I've been playing with ways to visualise Biodiversity Heritage Library content for a while (click here for a list of previous posts), and have occasionally surfaced to tweet a screenshot via twitpic.

I've added a feature to my Biodiversity Heritage Library viewer that should help make sense of the names found on a page. Until now I've displayed them as a list of "tags", which ignores the relations among the names.

Sadly I won't be at TDWG 2009, at least not in person. However, there is a session on wikis, which may contain this brief screencast of my iTaxon experiments. The screencast was made in haste, but tries to convey some of the ideas behind these experiments, especially the idea that by linking data together we can generate more interesting and rich views of objects such as scientific publications.

One of the more glaring limitations of my BHL viewer described in the previous post is that it can take a while to load all the page thumbnails (there can be hundreds). Given that one of the original motivations for this project was a faster viewer, this kinda sucks.

In between the chaos that is term-time I've been playing with ways to view Biodiversity Heritage Library content. The viewer is crude, and likely to go off-line at any moment while I fuss with it, the you can view an example here.

Continuing with my exploration of the Biodiversity Heritage Library one obstacle to linking BHL content with nomenclature databases is the lack of a consistent way to refer to the same bibliographic item (e.g., book or journal). For example, the Amphibia Species of the World (ASW) page for Gastrotheca aureomaculata gives the first reference for this name as: Gastrotheca aureomaculata Cochran and Goin, 1970, Bull. U.S. Natl.

Thinking about ways to improve the performance of some of my web servers I've begun to toy with Memcached.

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 first

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.
