Full title and description

ISO 24613-4:2021 — Language resource management — Lexical Markup Framework (LMF) — Part 4: TEI serialization. This part specifies an XML serialization of the LMF lexical model using the Text Encoding Initiative (TEI) Guidelines to represent lexical resources, including classes introduced in the LMF core, the MRD (machine-readable dictionary) extension and the etymological extension.

Abstract

This document defines how the lexical markup framework (LMF) model can be serialized as an XML schema consistent with TEI practice. The serialization maps LMF core components and extensions (MRD and etymology) to TEI constructs, enabling exchange, preservation and processing of lexicons and machine-readable dictionaries within TEI-based workflows.

Scope

Specifies a TEI-based XML serialization for the Lexical Markup Framework (LMF) models, covering the LMF core (ISO 24613-1), the machine-readable dictionary model (ISO 24613-2) and the etymological extension (ISO 24613-3). The standard provides element mappings, structural constraints and examples to ensure interoperability between LMF-conformant lexical resources and TEI-processing toolchains. It is intended to support exchange, archiving and processing of lexical data expressed in TEI XML while preserving the semantics of the underlying LMF model.

Key topics and requirements

• Mapping rules from LMF classes and attributes to TEI elements and attributes.
• Serialization patterns for lexical entries, senses, forms, relations and MRD-specific constructs.
• Guidance for encoding etymological information using TEI constructs aligned with the LMF etymology extension.
• Namespace, schema and conformance requirements for valid TEI-LMF documents.
• Examples and recommended best practices for producing interoperable TEI-serialized lexicons.
• Interoperability considerations with other parts of ISO 24613 and with TEI customization mechanisms.

Typical use and users

Used by lexicographers, computational linguists, language technology engineers, digital humanists, corpus and dictionary projects, and libraries or archives that produce, exchange or preserve lexical resources. Typical applications include building machine-readable dictionaries, lexical databases, lexicon exchange between tools, TEI-based corpora integration, and resource archiving with standardized metadata and structure.

FAQ

Q: What is this standard?

A: ISO 24613-4:2021 defines a TEI-based XML serialization for the Lexical Markup Framework (LMF), providing concrete mappings and conventions to represent LMF lexical structures using TEI.

Q: What does it cover?

A: It covers mapping of LMF core and extension classes (including MRD and etymology) to TEI elements, specifies serialization constraints, namespaces and conformance guidance, and provides examples and best practices for interoperable TEI-encoded lexica.

Q: Who typically uses it?

A: Lexicographers, NLP and language technology developers, digital humanities practitioners, archivists and institutions that create, exchange or preserve lexicons and machine-readable dictionary resources in TEI/XML form.

Q: Is it current or superseded?

A: ISO 24613-4:2021 was published on 15 January 2021 and is the current published part 4 of the ISO 24613 series. It replaces the earlier unified ISO 24613:2008 conceptually (the 2008 single-part has been withdrawn and the series reorganized into parts).

Q: Is it part of a series?

A: Yes — it is part of the ISO 24613 series (LMF). Key companion parts are ISO 24613-1 (core model), ISO 24613-2 (MRD model) and ISO 24613-3 (etymological extension).

Q: What are the key keywords?

A: LMF, TEI, XML, lexical markup, MRD, etymology, lexicon serialization, interoperability, ISO 24613.
