Overview
IEC 62605:2021 - "Multimedia systems and equipment - Multimedia e-publishing and e-books - Interchange format for e-dictionaries" - is an international standard that specifies an XML-based interchange format for e-dictionaries to be shared among publishers, content creators and manufacturers. This third edition (2021) cancels and replaces the 2016 edition and constitutes a technical revision that enhances data reuse, web-related usage and accessibility support.
Scope highlights
- Defines file formats and semantics for e-dictionary interchange (Annex A: XMDF‑LeXML; Annex B: LeXML).
- Focused on content interchange, not on device-specific rendering, printing-only elements, reading-device data formats, or security/DRM.
Key topics and technical requirements
- Interchange format structure: XML schemas and element/attribute sets that express dictionary structure, headwords, subheadwords, examples, pronunciations and inline formatting.
- Annex A (XMDF‑LeXML): normative definitions for file structure, identifiers (Page_ID, Object_ID, Char_ID), filenames, character types, coordinates, color, date/time, localization and RELAX NG specification.
- Annex B (LeXML): detailed elements for content structure and inline markup (headword elements, pronunciation, part‑of‑speech, examples, media and typesetting); provided in DTD syntax.
- Semantics and metadata: standardized semantics for search tables, content modules, object instances and adaptation/localization options.
- Accessibility & reusability: new attributes for accessibility-related functions and detailed markup to improve data reuse and web integration.
- Exclusions explicitly stated: the standard does not cover device rendering, final-print-only elements, reading-device formats or DRM/security mechanisms.
Practical applications and who uses it
IEC 62605 is primarily aimed at professionals who need robust, interoperable dictionary content exchange:
- Publishers and lexicographers preparing dictionary XML for distribution
- Content-conversion vendors converting print or legacy dictionaries into structured e-dictionary formats
- E-book and dictionary software manufacturers implementing import/export capabilities
- Localization and digital accessibility teams ensuring semantic and accessible dictionary content across platforms
- Archives and libraries requiring standardized interchange for long-term preservation
Typical uses include exchanging rich dictionary data between production teams and device makers, enabling search/interactivity in e-books, supporting multilingual and media-rich dictionaries, and improving cross-platform content reuse.
