摘要： To produce a continuous query for an append-only database, a client defined query first is converted into its minimal bounding non-decreasing monotone (hereinafter referred to as "monotonic increasing" query. This monotonic query, in turn, is converted into an incremental query, The resulting monotonically increasing incremental query then is installed on the database as a stored procedure that takes two date/time parameters (hereinafter referred to as "time" parameters), one of which (.tau.) identifies the last time the procedure was executed, and the other of which (t) identifies the current time. All database records are timestamped as of the time that they are entered into the database. Thus, in operation, more or less standard procedure calls periodically invoke each of the stored query procedures, thereby periodically executing the incremental queries over database records that have timestamps spanning successive time slots.
摘要翻译：为了产生仅针对append的数据库的连续查询，首先将客户定义的查询转换为其最小边界非递减单调（以下简称“单调递增”查询），然后将该单调查询转换为增量查询，然后将所得到的单调增长的增量查询作为存储过程安装在数据库中，该存储过程需要两个日期/时间参数（以下称为“时间”参数），其中一个（τ）标识最后一次执行过程，而另一个（t）标识当前时间，所有数据库记录在输入到数据库的时间内都是时间戳的，因此在操作中，或多或少的标准过程调用周期性地调用每个存储的查询过程从而周期性地对具有跨越连续时隙的时间戳的数据库记录执行增量查询。

摘要： A method in which access control programs (ACPs) permit controlled delegation of access rights from clients to untrusted intermediaries. ACPs are programs that encode arbitrary specifications of delegated access rights. In the method, a client creates an ACP and associates it with a request to a server, the request being made through one or more intermediaries. When processing a request received from an intermediary, the server executes the access control program to determine whether or not to grant the request.
摘要翻译：访问控制程序（ACP）允许将访问权限从客户端控制到不可信中介的方法。 ACP是编写授权访问权限的任意规范的程序。在该方法中，客户端创建ACP并将其与对服务器的请求相关联，该请求通过一个或多个中介进行。当处理从中介收到的请求时，服务器执行访问控制程序以确定是否授予请求。

摘要： A distributed system includes full and partial replicas of a set of data items that may be inserted, modified, or deleted by any replica. Replicas may occasionally synchronize with other arbitrarily chosen replicas to learn about updates. A replica's knowledge includes of one or more knowledge fragments, where each fragment indicates a set of items. A type of knowledge fragment, called a star knowledge fragment, contains versions associated with all items in the system. Star knowledge fragments are compact because the set of items stored at a replica need not be explicitly listed. Once all replicas know of all updates in the system, partial and full replicas will have the same compact star knowledge fragment.
摘要翻译：分布式系统包括可以由任何副本插入，修改或删除的一组数据项的完整和部分副本。副本可能偶尔与其他任意选择的副本进行同步，以了解更新。副本的知识包括一个或多个知识片段，其中每个片段指示一组项目。称为星型知识片段的知识片段类型包含与系统中所有项目相关联的版本。明星知识片段是紧凑的，因为存储在副本中的项目集不需要被明确列出。一旦所有副本都知道系统中的所有更新，部分和完全副本将具有相同的紧凑型星级知识片段。

摘要： A user-level controlled mechanism is interposed into a read/write path of a computer system. The mechanism can be implemented as properties attached to documents. Documents having properties attached thereto have the capability of separating the content of the document from the properties which describe the document. This separation of the document content from its properties allows for a user-level access and control of the properties thereby allowing a user flexibility in organizing, storing and retrieving documents. The mechanism allows a user to arrange collections of documents wherein a single document may appear in multiple collections. The properties of the present invention are user and document specific in the sense that they are associated with the user which attached the properties and are directed to control of specific documents.
摘要翻译：用户级控制的机制插入到计算机系统的读/写路径中。该机制可以实现为附加到文档的属性。具有附加属性的文档具有将文档的内容与描述文档的属性分离的能力。文档内容与其属性的这种分离允许用户级别访问和控制属性，从而允许用户组织，存储和检索文档的灵活性。该机制允许用户安排文档的集合，其中单个文档可以出现在多个集合中。本发明的属性是用户和文档特定的意义上，它们与附加属性的用户相关联，并被指导用于控制特定文档。

摘要： A document management system is provided which organizes, stores and retrieves documents according to properties attached to the documents. A property attachment mechanism allows a user to attach arbitrary static and active properties to a document. The active properties include executable code which dynamically change system configuration of the document in response to a triggering event which is predefined by the user. The present invention eliminates the generally tedious and error-prone process of configuring and reconfiguring an existing system configuration in response to new or changing user needs.
摘要翻译：提供了一种文件管理系统，该文档管理系统根据文档所附的属性来组织，存储和检索文档。属性附加机制允许用户将任意的静态和活动属性附加到文档。活动属性包括响应于由用户预定义的触发事件来动态地改变文档的系统配置的可执行代码。本发明消除了响应于新的或改变的用户需求而配置和重新配置现有系统配置的通常繁琐而容易出错的过程。

摘要： A distributed system synchronizes replica devices with respect to items that may be inserted, modified, or deleted by any of the replica devices. Replicas may synchronize with other replicas to learn about updates to items. Each replica device may include a high-fidelity replication platform and/or a low-fidelity replication platform. The low-fidelity replication platforms may synchronize low-fidelity versions of items among the replica devices, and the high-fidelity replication platforms may synchronize high-fidelity versions of items among the replica devices. Each replica device may include a fidelity manager that copies high-fidelity versions of items from the high-fidelity replication platform, generates low-fidelity versions of the items from the high-fidelity versions of the items, and adds the low-fidelity versions of the items to the low-fidelity replication platforms. The fidelity managers may further integrate changes made to low-fidelity versions of items into the corresponding high-fidelity versions of the items.

摘要： A protocol for replicating replicas in a sync community. Each replica maintains a knowledge that represents changes that the replica is aware of. Each replica does not typically maintain knowledge about other replicas. The protocol includes messages that include knowledge about changes on the various replicas. Using the knowledge, the replicas can enumerate changes and send the changes using asynchronous messages that do not need to be received in any particular order. The protocol enables filters to ensure that a valid replication is possible using a minimum knowledge argument. The protocol also enables replicas to partially replicate using filtered knowledge.
摘要翻译：用于在同步社区中复制副本的协议。每个副本都维护一个代表该副本所知的变化的知识。每个副本通常不会保留关于其他副本的知识。该协议包括包含有关各种副本上的更改的知识的消息。使用知识，副本可以枚举更改，并使用不需要以任何特定顺序接收的异步消息发送更改。该协议允许过滤器确保使用最小知识参数可以进行有效的复制。该协议还使复制品能够使用过滤的知识进行部分复制。

摘要： A document management system is provided which organizes, stores and retrieves documents according to properties attached to the documents. A property attachment mechanism allows an application to attach arbitrary static and active properties to a document. The active properties include executable code which perform document management functions to control the state and behavior of the document in response to a triggering event. In this manner, the state and behavior of the document is provided to a user and is accurately maintained even when the application is not running.

摘要： A database of interests is maintained in a distributed computing system to register the individual interests of users in centrally stored non-textual media files, such as digital voice, music, scanned-in image, and video files. Uniquely named piece table style persistent data structures are employed to give users controlled access to the underlying non-textual media files by embedded name reference to such piece tables in ordinary messages or text files, so a database of piece tables is also maintained. A garbage collector periodically enumerates the interest database to delete interest entries which have been invalidated. Aged piece tables are deleted from the reference database when there no longer are any recorded interests referring to them, and non-textual media files are deleted to reclaim the storage space allocated to them when there no longer are any piece tables referring to them.
