Language resource management — Morphosyntactic annotation framework (MAF) — Part 1: Core model

Scope

This document establishes a framework for the representation of annotations of word-sized units in texts. Such annotations describe tokens, their relationship with lexical units (word-forms), and the relevant morphosyntactic properties. This document proposes a metamodel for morphosyntactic annotation that can be augmented with references to data categories contained in a data category repository conforming to ISO 12620-2. It also defines an XML serialization for morphosyntactic annotations, according to the principles laid out in the TEI Guidelines (see Reference [31]).
This document does not apply to structural ambiguities or the structure and composition of morphosyntactic tagsets.
This document does not address the linguistic choices that identify tokens or determine the language- or context-particular relationships between tokens and word-forms.
