Overview
ISO 16642:2017 - Terminological markup framework (TMF) - specifies a standardized framework for representing data recorded in terminological data collections (TDCs). The standard defines a metamodel and methods for describing specific terminological markup languages (TMLs) expressed in XML. TMF provides mechanisms to implement constraints, define XML styles and vocabularies, and establish the conditions that allow data in one TML to be mapped onto another. Its purpose is to support the development, management and interchange of terminological data across tools and organizations.
Key topics and technical requirements
- Metamodel and modular approach: TMF separates an abstract metamodel (shared structural components) from data models that add concrete data categories for specific TDCs.
- Terminological Markup Languages (TMLs): XML implementations of the TMF metamodel; specified by expansion trees, data categories, XML styles and vocabularies.
- Data categories and repositories: Use of data categories (elementary descriptors) and referencing a data category repository (example: DatCatInfo) to ensure consistent semantics.
- Constraints and conformance: TMF defines mechanisms to implement constraints in a TML and requirements for compliance, though it does not prescribe specific constraints for individual TMLs.
- Interchange & interoperability: Conditions and methods for mapping between different TMLs to enable data exchange between systems.
- Language representation and annotations: Guidance on representing languages, language sections, term components and annotations within the XML outline.
- Implementation guidance: Steps for defining and implementing a TML, anchoring data categories to XML outlines, styles, vocabularies, datatypes, annotations and brackets.
Applications and users
ISO 16642:2017 is practical for organizations and professionals working with terminology and multilingual content:
- Terminology managers and lexicographers designing or standardizing terminological collections.
- Localization and translation teams needing consistent termbases for translation memory and content reuse.
- Software developers and architects building terminology management systems, converters or XML-based exchange tools.
- Content and knowledge managers in corporations, standards bodies and government agencies who require interoperable terminological data exchange.
- Facilitates adoption of formats such as TBX (ISO 30042) and the creation of interoperable XML TMLs for data exchange.
