Mapping Web Services

Currently there are three different and independant web services which offer mappings of biological database identifiers:

• The BioMinT GPSDB Server: http://biomint.oefai.at/
  
• AliasServer: http://cbi.labri.fr/outils/alias/
  
• ProThesaurus: http://services.bio.ifi.lmu.de/prothesaurus

If you know any other web service or server let us know and add a comment.
