OverviewThe National Terminology Mapping Library is an Australian Digital Health Agency initiative supporting healthcare interoperability across Australia. It provides access to a curated set of clinically safe, well-maintained, and nationally relevant terminology maps. These maps assist software developers, clinicians, researchers, and vendors by enabling translation between different clinical coding systems, reducing duplication of effort, and supporting consistency in digital health delivery. PurposeEstablished under Action 2.11 of the National Healthcare Interoperability Plan, the Library’s purpose is to provide a national resource that facilitates translation between various health classification and terminology standards. These maps support seamless data sharing, enhance data quality, and reduce implementation time for new digital health solutions.What the Library OffersAccess to high-value, validated mapping tables Support for multiple classification systemsMetadata for each map including access, maintenance frequency, directionality, licensing and hyperlinks Alignment with ISO 21564 MapQual quality framework A single, discoverable point of truth to promote reuse and reduce duplication Who Should Use ItClinical system vendors seeking standard code translations Healthcare service providers needing to meet national reporting requirements Policy analysts and researchers requiring data harmonisation Developers implementing software requiring clinical data mapping AccessThe library is hosted on the Agency’s Standards Catalogue and includes both open-access and licensed maps.
