本文档指定如何将文档（实例数据，而不是数据模式）表示为图形（而不是可视化）。它没有具体说明如何可视化或操作文档数据，但其目的是通过允许各种基于图形的灵活用户界面，使人们更容易编写和理解文档，可能还包括文档可视化实践（见简介）。在这方面，本文档也没有指定对现有文档的注释，而是指定了具有显式逻辑结构的文档模式。 购买本文件时可获得的所有当前修订均包含在购买本文件中。

This document specifies how to represent (not visualize) documents (instance data, not data schemas) as graphs. It does not specify how to visualize or operate on document data, but it aims at making documents easier for people to compose and comprehend by allowing for various graph-based flexible user interfaces, possibly incorporating document-visualization practices (see Introduction). In this connection, this document does not specify annotations to existing documents either, but rather it specifies a schema of documents with explicit logical structures.All current amendments available at time of purchase are included with the purchase of this document.
