IHTSDO

Advanced SNOMED CT workspace for terminologists, clinical informaticists, and SNOMED CT editors. Use when the user wants to write or run ECL, audit concept modelling, compare editions, inspect native concept data, trace ancestor/descendant chains, or identify terminology quality issues.

Guided SNOMED CT exploration for any user. Use when the user wants to find, look up, validate, or query SNOMED CT concepts, build value sets, check subsumption, or understand the clinical terminology hierarchy. Works with plain clinical language — no SNOMED CT or ECL knowledge required.
