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.

The 52,956 links from NCBI to Wikipedia that I've been busy creating are now "live." If you go to a NCBI taxon such as Sphaerius you'll see something like this:Clicking the "Wikipedia" link takes you to the Wikipedia page for this taxon.

In an earlier post I discussed linking NCBI taxonomy to Wikipedia. One way to tackle this is to add NCBI Taxonomy ID to Wikipedia pages. I reopened the case for adding the Taxonomy IDs to the Taxobox on each taxon page, but this met with substantial resistance.
