⚠️ LEARNING EXAMPLE — NOT A NATIONAL STANDARD ⚠️

This IG demonstrates how to specify custom terminology service behaviour in FHIR terms. It is not endorsed by the Philippine Statistics Authority or any government body. Use it to learn the pattern of writing a conformance specification for a terminology plugin.

Purpose

This IG defines what a PSGC-capable FHIR terminology server must support. It exists so that:

  • Multiple server implementations can interoperate on PSGC codes
  • Clients know what operations, properties, and behaviour to expect
  • The specification is expressed in standard FHIR conformance artefacts

Reference Implementation

The HAPI FHIR PSGC Terminology Plugin is the reference implementation of this IG. It proves the specification is implementable. The tutorial wiki teaches the implementation techniques.

Audience

  • Server implementers building PSGC support for any FHIR server
  • IG authors learning to specify custom terminology services
  • Plugin developers wanting a conformance target for their code
