Overview
ISO 12620-1:2022 - Management of terminology resources - Data categories - Part 1: Specifications defines how data category specifications (DC specifications) for language resources should be structured, documented and maintained. It sets requirements and recommendations for creating formal, reusable descriptions of data categories (e.g., /part of speech/, /definition/) and explains how those specifications can be published and referenced from a data category repository (DCR). This part focuses on the structure and rationale for specifications; repository procedures are covered in ISO 12620-2.
Key topics and technical requirements
ISO 12620-1 covers the following technical topics and concrete requirements:
- Identifiers and names
- Unique, stable mnemonic identifiers
- Persistent identifiers (PIDs / URIs) for long-term reference
- Canonical and language‑specific data category names
- Data category concepts
- Definition of a data category as a class of related data items
- Distinction among open, closed, constrained and simple conceptual domains
- Use of picklist values for closed domains
- Data category specifications (DC specifications)
- Complete descriptive record: name, definition, examples, comments
- Content model describing permissible values (free text, enumerated, constrained)
- Documentation of implementation details across projects, resource types and languages
- Management processes
- Referencing mechanisms (using PIDs)
- Harmonization and vetting procedures to resolve duplicates and discrepancies
- Administrative metadata: creation/modification dates, authors, vetting status (proposed, under review, approved, deprecated)
- Related structural elements
- Conceptual domains, data category selections, data elementarity, and profiles
Applications and who uses it
ISO 12620-1 is intended for researchers and practitioners involved in language resource management, including:
- Terminology managers and lexicographers
- Corpus developers and annotators
- Language technology and NLP engineers building interoperable resources
- Localization and knowledge‑management professionals who need consistent metadata
Practical benefits include improved interoperability, consistent annotation across projects, easier reuse of terminology and lexical resources, and persistent, machine-actionable references to data category definitions.

ISO 12620-1:2022 is essential for organizations aiming to standardize metadata and annotation schemes for multilingual language resources and to ensure long-term, interoperable use of data categories.
