Overview - ISO/TS 6304:2022 (Traditional Chinese Medicine, TCM)
ISO/TS 6304:2022 specifies a minimal categorial structure for representing disorders in Traditional Chinese Medicine (TCM) within terminological resources. The Technical Specification defines domain constraints and a concept model built around four subcategories - body parts, causative agents, pathological process, and manifestation - and formalizes directed semantic links between disorder terms and these categories. The document is intended to help standardize TCM disease terminology for computer processing, mapping and knowledge engineering, but it does not provide treatment procedures, device specifications, exhaustive term lists, or a comprehensive TCM classification.
Key topics and technical requirements
- Four characterized categories
- Body part - anatomical and virtual structures (e.g., viscera, meridians)
- Causative agent - elements producing disorders (e.g., wind, cold, seven emotions)
- Pathological process - organic or disease processes (e.g., accumulation)
- Manifestation - observable signs or symptoms (e.g., pain)
- Semantic links (formal directed relations) that link a disorder to categories:
- Occurs in (disorder → body part)
- Has causative agent of (disorder → causative agent)
- Has pathological process of (disorder → pathological process)
- Has manifestation of (disorder → manifestation)
- Terminology constraints for use in terminological resources and health informatics systems; suitable as a core model for disorder representation in TCM.
- Explicit exclusions: no exhaustive category hierarchy, no clinical treatments, no device standards, and no detailed term descriptions for subcategories.
Practical applications and users
ISO/TS 6304:2022 is useful where standardized TCM disorder representation is required:
- Developers of health informatics and electronic medical records (EMR) systems that integrate TCM terms.
- Terminology and ontology engineers building TCM terminological resources, semantic networks, or knowledge graphs.
- NLP/text-mining teams and digital humanities projects processing ancient TCM documents and extracting disorder information.
- Designers of clinical decision support tools that need a consistent core model to map TCM disorders to computational representations.
- Standards bodies, researchers and integrators working to map or harmonize TCM terminology with Western medicine terminologies.
