    • A method for executing searches for resources that span more than one private resource repository in a restricted-access resource sharing system is disclosed. The system includes at least one server node (12) and multiple peer nodes (16a-16d) connected to a network. Resources, such as data digital images, may be retrieved from the nodes based by issuing queries containing terms matching the metadata associated with the resources. The method includes maintaining storage of resources and associated metadata on respective peer nodes, wherein the associated metadata is based on at least one metadata vocabulary. Each of the peer nodes is allowed to indicate to the server that the metadata vocabularies associated with the resources are designated as private, thereby becoming a restricted access peer node. If a first restricted access peer node specifies to the server which metadata vocabularies the first restricted access peer node supports, a first level of privacy is provided whereby search queries received by the server that use the specified metadata vocabularies are passed to the first respective restricted access peer nodes for processing, while searches that do not use the specified vocabularies are processed by the server. If the first restricted access peer node does not specify to the server which metadata vocabularies the first restricted access peer node supports, a second level of privacy is provided whereby search queries received by the server are passed to the first respective restricted access peer nodes for processing.
    • 公开了一种用于执行搜索跨越受限访问资源共享系统中的多于一个私人资源储存库的资源的方法。 该系统包括连接到网络的至少一个服务器节点(12)和多个对等节点(16a-16d)。 诸如数据数字图像之类的资源可以基于通过发布包含与资源相关联的元数据匹配的项的查询从节点中检索。 该方法包括在各个对等节点上维持资源和关联元数据的存储,其中关联的元数据基于至少一个元数据词汇表。 允许每个对等节点向服务器指示与资源相关联的元数据词汇表被指定为私有的,从而变成受限的接入对等节点。 如果第一受限接入对等节点向服务器向服务器指定第一受限接入对等节点支持哪些元数据词汇表,则提供第一隐私等级,由此服务器接收到的使用指定元数据词汇表的搜索查询被传递给第一相应受限接入 对等节点进行处理,而不使用指定词汇表的搜索由服务器处理。 如果第一受限接入对等节点没有向服务器指定第一受限接入对等节点支持哪些元数据词汇表,则提供第二隐私等级,从而由服务器接收的搜索查询被传递到第一相应受限接入对等节点以进行处理 。
