本文档描述了词法标记框架（LMF）模型的序列化，该模型定义为一种可扩展标记语言（XML）模型，该模型源自语言库交换（LBX）模式，并符合W3C XML模式。本系列介绍了ISO？24613-1（核心模型）、ISO？24613-2（机器可读字典（MRD）模型）和ISO？24613-3（词源扩展）的类、数据类别和机制。

This document describes the serialization of the lexical markup framework (LMF) model defined as an extensible markup language (XML) model derived from the language base exchange (LBX) schema and compliant with the W3C XML schema. This serialization covers the classes, data categories, and mechanisms of ISO？24613-1 (core model), ISO？24613-2 (machine-readable dictionary (MRD) model), and ISO？24613-3 (etymological extension).
