ClaML
ClaML (EN14463) is a simple XML application for the exchange and distribution of classification schemes. ClaML has been adopted by the WHO to distribute their family of international classifications. Here is a small example ClaML file.
SNOB can import classifications in ClaML and use this to display the rubrics of crossmapped classifications, but also of legacy SNOMED and CTV3 codes.
