Australian ants online
The Australia National Insect Collection has an online resource of Australian ants that provides species maps and Google Earth files of specimen distributions.
A potentially useful source of data, but the KML files don't include specimen codes, and there is an unfortunate disconnect between specimen codes and ids used to link to them. For example, in the specimen list for Myrmecia midas, the first specimen has a "MaterialID" of 128315, yet the ANIC accession code for this specimen is 32-012805. Pity this identifier is not made of in the link to the data.
The site also displays specimen metadata as an HTML table -- this information is also available as a CSV file. This is an example where a touch more effort would make it truly useful as a source of data. Something as simple as RDF with the specimen URL as URI would be a big help, but this could be achieved by some judicious screen scraping...
Just realised, the data is served up by GBIF, which makes life much easier.
