Section 1h: Cross-paradigm/Domain Analysis Models

HL7 Logical Model: Standardized Terminology Knowledgebase, Release 1

DESCRIPTION

This specification describes the requirements needed to manage terminology produced by a variety of organizations across the healthcare enterprise. The healthcare enterprise needs an extensive terminology foundation and the ability to implement extensions to support diverse informatics systems.

This specification is intended to support standard terminology modules, value sets, and coding systems as well as local terms and equivalence mappings.

A standard-based Terminology Knowledge Architecture (Tinkar) specification is necessary to support the operation of a variety of systems intended to deliver knowledge management for terminology to vendors, providers, and standards development organizations, like Health Level Seven International (HL7).

ALTERNATIVE NAMES

HL7 Logical Model: Standardized Terminology Knowledgebase, Release 1 may also go by the following names or acronyms:

Tinkar

BENEFITS

  • Creates a logical model to represent HL7 Codesets, SNOMED, LOINC, RxNorm, and other clinical terminologies.
  • Enables representation of machine-processable semantics for standard terminology and local content/concepts.
  • Describes how a "sanctioned standard terminology knowledge base" can allow integration of standard content (e.g., currently LOINC can’t be modeled in a SCT model or published in SCT format).

IMPLEMENTATIONS/CASE STUDIES

  • Logica

DEVELOPMENT BACKGROUND

There is an example implementation of Tinkar, referred to as Komet (https://github.com/logicahealth/komet), which demonstrates how various terminologies, such as SNOMED CT®, LOINC®, RxNorm, and HL7 terminologies shall be reproducibly represented using Tinkar.

The Komet browser allows users to view the search Concepts, view the Concept details (Semantics), and navigate hierarchies, as well as many other functions that are outside the scope of this ballot.

Java Reference Classes for the Tinkar model can be accessed here: (https://github.com/HL7/tinkar-java).

C# Reference Classes can be accessed here:(https://github.com/HL7/tinkar-cs).
