本文提出了一种为XML文档提供灵活安全粒度的访问控制框架。RDF语句用于表示安全对象和表达安全策略。定义了简单安全对象和关联安全对象的概念。我们的模型允许表达和实施对XML树及其关联的访问控制。对应于(S，o，±a)三元组的访问控制规则被表示为具有访问类型、用户和对象属性的rdf语句。为每个用户维护允许使用时间数据进行决策的历史文件。
In this paper we present an access control framework that provides flexible security granularity for XML documents. RDF statements are used to represent security objects and to express security policy. The concepts of simple security object and association security object are defined. Our model allows to express and enforce access control on XML trees and their associations. Access control rules, corresponding to (s, o, ±a) triples, are represented as RDF statements with properties access type, user, and object. A history file is maintained for each user that allows decision-making using temporal data.
