There's a recent thread on the Encyclopedia of Life concerning erroneous images for the crab Leptograpsus . This is a crab I used to chase around rooks on stormy west-coast beaches near Auckland, so I was a little surprised to see the EOL page for Leptograpsus looks like this: The name and classification is the crab, but the image is of a fish ( Lethrinus variegatus ). Perhaps at some point in aggregating the images

This post arose from an ongoing email conversation with Tony Rees about extracting and annotating taxonomic names. In BioStor I use the GBIF classification to display the taxonomic names found in the OCR text in the form of a tree. The idea is to give the reader a sense of "what the paper is about". I also use the classification to help link to GBIF occurrence records.

In the spirit of the Would you give me a grant experiment? [1] here's the draft of a proposal I'm working on for the Computable Data Challenge. It's an attempt to merge taxonomic names, the primary literature, and phylogenetics into one all-singing, all-dancing website that makes it easy to browse names, see the publications relevant to those names, and see what, if anything, we know about the phylogeny of those taxa.

Dark taxa have become even darker. NCBI has pulled the plug on large numbers of DNA barcode sequences that lack scientific names. For example, taxon Cyclopoida sp. BOLD:AAG9771 (tax_id 818059) now has a sparse page that has no associated sequences. From an earlier download of EMBL I know that this taxon is associated with at least 5 sequences, such as GU679674. But if you go to that sequence you get this: So the the sequence is hidden.

Based on recent discussions my sense is that our community will continue to thrash the issue of identifiers to death, repeating many of the debates that have gone on (and will go on) in other areas. To be trite, it seems to me we have three criteria: cheap , resolvable , and persistent . We get to pick two.

Now we are awash in challenges! EOL has announced its Computable Data Challenge: Some $US 50,000 is on offer. "Challenge" is perhaps a misnomer, as EOL is offering this money not as a prize at the end, but rather to fund one or more proposals (submitted by 22 May) that are accepted.

When I think of the Biodiversity Heritage Library (BHL) or GBIF I tend to think of taxonomy and biodiversity. Folk wisdom has it that BHL is full of old books, mostly pre-1923. Great for finding old taxonomic names, or nice artwork, but not exactly "modern" biology. GBIF is mainly about displaying organism distributions based on museum specimens, the primary data of taxonomic research.

The iEvoBio 2012 Challenge has been announced, and the topic is synthesizing phylogenies. The task: The rules of this challenge are: The set of trees you use must have at least 10,000 leaves in total. Acceptable entries could be a set comprising 2,500 distinct trees covering the same four taxa, a single tree with 10,000+ leaves, or anything in between. Your results must be scientifically new.

One reason I'm pursuing the theme of specimen identifiers (and identifiers in general) is the central role they play in annotating databases. To give a concrete example, I (among others) have argued for a wiki-style annotation layer on top of GenBank to capture things such as sequencing errors, updated species names, etc. Annotation is a lot easier if we have consistent identifiers for the things being annotated.

Sometimes I need to remind myself just why I'm spending so much time trying to make sense of other people's data, and why I go on (and on) about identifiers. One reason for my obsession is I want data to be "sticky", like the burrs shown in the photo above (Who invented velcro? by A-dep). Shared identifiers are like the hooks on the burrs, if two pieces of data have the same identifier they will stick together.
