- Reference Terminologies - is maintained by a recognized authority (Terminology Advisory Group) who maintains the coding, mapping and standardization of the terminologies used. This terminologies are meant for semantic interoperability. Example: Acute nasopharyngitis maybe represented as J00 as par ICD10 coding standard
- Interface Terminologies - are the terminologies used at the points-of-care (e.g hospital). Example: Common cold. This "common cold" is mapped to J00
