SNOB is something more than just a SNOMED browser. It allows you to edit existing descriptions; add new descriptions; export the content to file; import files in Release Format 1 and 2; import multiple releases of SNOMED into the same database and see a changelog for each concept. SNOB supports a multi-lingual user interface. SNOB uses a lexicon to improve search results and translate descriptions to other languages.

In the GALEN and GALEN-In-Use projects I have developed a GALEN Terminology Server and Classification Workbench (ClaW). An evaluation version of ClaW can be downloaded from OpenGALEN.

I have designed and maintained the OpenGALEN website and implemented an online browser on the OpenGALEN model. The same browser is also used by the Dutch WHO-FIC Collaborating Centre as an online classification browser, and by the University of Nijmegen.

I'm also the main designer of the Classification Markup Language (ClaML), which is European Norm 14463 for the distribution of classifications. ClaML has been adopted by the WHO to distribute their family of international classifications.
