Awoke this morning to the sad news (via Scott Miller) that Scott Federhen of the NCBI had died. Anyone using the NCBI taxonomy is a beneficiary of Scott's work on bring together taxonomy and genomic data. Scott contributed both directly and indirectly to this blog.
In a recent Twitter conversation including David Shorthous and myself (and other poor souls who got dragged in) we discussed how to demonstrate that adopting JSON-LD as a simple linked-data friendly format might help bootstrap the long awaited "biodiversity knowledge graph" (see below for some suggestions for keeping JSON-LD simple). David suggests partnering with "Three small, early adopting projects". I disagree.
If we view biodiversity data as part of the "biodiversity knowledge graph" then specimens are a fairly central feature of that graph. I'm looking at ways to link specimens to sequences, taxa, publications, etc., and doing this across multiple data providers.
Scott Federhen told me about a nice new feature in GenBank that he's described in a piece for NCBI News. The NCBI taxonomy database now shows a its of type material (where known), and the GenBank sequence database "knows: about types. Here's the summary:You can query for sequences from type using the query "sequence from type"[filter]. This could lead to some nice automated tools.
In response to Rutger Vos's question I've started to add GBIF taxon ids to the iPhylo Linkout website. If you've not come across iPhylo Linkout, it's a Semantic Mediawiki-based site were I maintain links between the NCBI taxonomy and other resources, such as Wikipedia and the BBC Nature Wildlife finder. For more background seePage, R. D. M. (2011). Linking NCBI to Wikipedia: a wiki-based approach. PLoS Currents, 3, RRN1228.
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.
Last week I was at the NSF "Assembling, Visualising and Analysing the Tree of Life" Ideas Lab, run by KnowInnovation.com/. It was an interesting experience, essentially a structured week of brainstorming ideas.One thing I came away with is the feeling that our notions of the "tree of life" are fuzzy, contradictory, and often probably unobtainable.
In an earlier post (Are names really the key to the big new biology?, I questioned Patterson et al.'s assertion in a recent TREE article (doi:10.1016/j.tree.2010.09.004) that names are key to the new biology.In this post I'm going to revisit this idea by doing a quick analysis of how many species in GenBank have "proper" scientific names, and whether the number of named species has changed over time.
My paper describing the mapping between NCBI and Wikipedia has been published in PLoS Currents: Tree of Life. You can see the paper here. It's only just gone live, so it's yet to get a PubMed Central number (one of the nice features of PLoS Currents is that the articles get archived in PMC).Publishing in PLoS Currents: Tree of Life was a pleasant experience. The Google Knol editing environment was easy to use, and the reviewing process quick.
Déjà vu is a scary thing. Four years ago I released a mapping between names in TreeBASE and other databases called TBMap (described here: doi:10.1186/1471-2105-8-158). Today I find myself releasing yet another mapping, as part of my NCBI to Wikipedia project. By embedding the mapping in a wiki, it can be edited, so the kinds of problems I encountered with TbMap, recounted here, here, and here.
