语义Web由许多可用URI命名的RDF图组成。本文扩展了RDF的语法和语义，以涵盖这样的命名图。这使得RDF语句能够描述图形，这在许多语义Web应用程序领域都是有益的。命名图给出了抽象语法、形式语义、XML语法和基于N3的语法。SPARQL是一种适用于命名图的查询语言。详细讨论的一个具体应用领域是描述来源信息。本文提供了一个正式定义的框架，适合作为语义Web信任层的基础。(c)2005 Elsevier B.V.保留所有权利。
The Semantic Web consists of many RDF graphs nameable by URIs. This paper extends the syntax and semantics of RDF to cover such named graphs. This enables RDF statements that describe graphs, which is beneficial in many Semantic Web application areas. Named graphs are given an abstract syntax, a formal semantics, an XML syntax, and a syntax based on N3. SPARQL is a query language applicable to named graphs. A specific application area discussed in detail is that of describing provenance information. This paper provides a formally defined framework suited to being a foundation for the Semantic Web trust layer. (c) 2005 Elsevier B.V. All rights reserved.
