本文为自然语言文本和多模态交互中的指称现象的注释和表示提供了一个全面的模型。这种现象可以涵盖简单的回指或共指机制，以及更复杂的桥接或多模态机制。它提供了XML格式的参考序列化，定义为TEI P5指南的定制。此外，本文件还描述了与参考实体和链接结构相关的核心数据类别，以及将一致性模型作为具体数据格式实现所需的注释方案和序列化机制的描述。

This document provides a comprehensive model for the annotation and representation of referential phenomena in natural language texts and multimodal interactions. Such phenomena can cover simple anaphoric or coreferential mechanisms as well as more complex bridging or multimodal mechanisms. It provides a reference serialisation in XML defined as a customisation of the TEI P5 guidelines. In addition, the document describes the core data categories related to referential entities and link structures, and also needed for the description of annotation schemes and serialisation mechanisms for implementing conformant models as concrete data formats.
