- 230 namespaces
- 35 different internal query titles (some of these map to the same URI pattern, so there are not this many URI query options)
- 140 provider options, including a large number of /html/database:identifier providers which redirect to HTML pages which describe the Bio2RDF Identifier as well as the Bio2RDF SPARQL endpoints
A list of the actual provider URL's mapped back to namespaces and queries can be found by downloading the Bio2RDF Servlet and changing a setting in log4j.properties to make the page more verbose. If the setting were turned on for the public mirrors it would result in a very large file each time.
