My BioStor project has reached over 13,000 articles, making it a sizeable respository of open access articles on biodiversity. It's still a tiny fraction of what could be extracted from the Biodiversity Heritage Library (BHL), but perhaps it's worth taking stock of what's there. Coverage One pleasing discovery is that, despite the 1923 cut-off due to U.S. copyright, BHL contains a lot of post-1923 articles.

Given that a new decade prompts predictions, as well as New Year's resolutions, and that 2010 is the International Year of Biodiversity, which comes complete with glossy web sites and calls for action, I'm making some predictions of my own, inspired in part by Eric Hellman's Ten Predictions for the Next Ten Years. I won't be nearly as bold as Eric, I'm limiting myself to biodiversity informatics, and the coming year.

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. What I'd like to do is load the thumbnails only when I need them, rather than all at once at the start -- in other words I'd like to implement lazy loading.

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. These notes are to remind me how to set it up (I'm using Mac OS X 10.5, Apache 2 and PHP 5.2.10, as provided by Apple). Erik's blog post Memcached with PHP on Mac OS X has a step-by-step guide, based on the post Setup a Memcached-Enabled MAMP Sandbox Environment by Nate Haug, and I've basically followed the steps they outline.
