Focused on UK researchers. "Currently this service and site are used for testing and validation of the in-development software prototype for the Names project. This service and site are not intended for use in live external applications or services except for experimentation as the availability, data and API are currently all subject to change." Not sure if whole data set is available.
Available as bulk download as MADS/RDF. "We'll make a SKOS/RDF download available in the near future. We are offering two serializations: n-triples and RDF/XML."
Based on book publications rather than journal publications.
A taxonomy of biological organisms created and maintained to support the Universal Protein Resource (UniProt), a collection of databases providing a comprehensive protein sequencing resource. Provides official species names, common names and synonyms - either alternate common names or occasionally outdated Latin names. For viruses, a list of hosts is included if the virus has protein sequences listed in the UniProt databases.
Database of records is not publicly accessible or searchable, but API info suggests it might be accessible to developers through the API http://www.zotero.org/support/dev/start.
Also other portions of the physical, social and mathematical sciences that are pertinent to the study of cognition.
An open access subset of the records are harvestable using OAI-PMH interface http://www.ncbi.nlm.nih.gov/guide/howto/dwn-records/. Also the CISTI/CIHI collection http://pubmedcentralcanada.ca/oai.cgi?verb=Identify
Hubmed: Alternative interface for accessing PubMed data.
Also accessible via OKF http://openbiblio.net/2011/05/23/medline-dataset/
