Snow Owl Client Reference


UMLS (Unified Medical Language System) code systems are supported by Snow Owl in read-only mode. To obtain the UMLS content to be imported, please visit their website and download the Full Release archive. The full release includes their NLM MetamorphoSys tooling, which allows the creation of a customized subset with only the code systems required to be imported to Snow Owl. When selecting the export format for the code systems, choose the RRF files. Once the files are created by the NLM MetamorphoSys tooling, the results need to be archived in a standard zip file.
