    摘要： The present invention describes a method for selectively delivering electronic messages to an identified user or users in a system of mobile and fixed devices, including multiple display devices and multiple users, based on the context of the system and the environment of the identified user. Electronic messages intended for an identified user or users may be given a level of privacy and a level priority, and contextual attributes for its delivery may be specified. The system perceives contextual attributes for the recipient user or users, including display devices in close proximity to the identified users, and determines a display property for said electronic message based on the contextual attributes, the user profile properties of each user, and the level of privacy and level of priority of the electronic message. The display property may designate immediate delivery on a particular display device, a notification on a particular display device, or storage of the message until the contextual attributes of the recipient user is consistent with the specified contextual attributes of the electronic message.

    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 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： A hierarchical system is disclosed for synchronizing partially-replicated collections that provides guaranteed paths of information to all replicas in a collection. Each partial replica is assigned a parent replica to act as a proxy on its behalf, and with which the replica synchronizes regularly. Each parent replica is responsible for one or more child replicas. Parent replicas have filters which are either the same as, or more inclusive than, their child replicas, and parent replicas thus store and synchronize all objects that are of interest to their one or more child replicas.

    摘要： A document management system is provided which organizes, stores and retrieves documents in accordance with document properties. A property attachment mechanism allows a user to define and attach static properties and/or active properties to a document. The active properties include executable code which control the behavior of the document contents. Upon transferring a document to another user, system, or environment, the document management system combines the document content and properties as a self-contained document which can interpret and manipulate its own contents. In this manner, a receiving user does not require additional applications in order to manipulate the document contents into a usable format. The self-contained document interprets and manipulates itself using its active properties to provide a useful document to the receiving user.

    摘要： Write operations for weakly consistent replicated database systems have embedded conflict detection and conflict resolution procedures for identifying and resolving, respectively conflicts between such write operations and the current state of any given instance of such a database. These write operations are committed to a firm execution order by the host for one instance of such a database, and this execution order propagates to the other instances of the database. Accordingly, a write log distinguishes between the writes that are known to be committed to a firm execution order (the "tentative writes") is maintained for each instance of the database, thereby enabling the user to explicitly identifying the stable data and the potentially unstable data in any given instance of the database. Furthermore, provision is made for enabling users to select from a set of predefined consistency guarantees across all instances of such a database for any given session.

    摘要： The present invention provides client-selected consistency guarantees to clients of a weakly consistent replicated database on a per "session" basis. The clients have access to utilities which allow the clients to, individually or collectively, define a "session" over which the selected guarantees are enforced. A "session" is broadly defined as a sequence of logically related Reads and Writes to the database. Sessions are initiated and terminated substantially independently of other sessions which may exist concurrently. Clients are allowed, however, to clone sessions and/or merge sessions with other clients. Clients select a minimum relevant subset of guarantees from among a set of pre-defined consistency guarantees, where "relevancy" is a client determined factor. At any given time, the system may be enforcing a number of different combinations of consistency guarantees. The guarantees ensure that all clients participating in a particular session view the database as having certain conditions of data consistency--the consistency of which is only provided with respect to the participants' Read and Write requests. Clients are allowed to downgrade their selected guarantees during the course of their sessions. One implementation of the present invention permits the selection of any one of four consistency guarantees.

    摘要翻译： 本发明在每个“会话”的基础上向弱一致的复制数据库的客户端提供客户选择的一致性保证。 客户可以访问实用程序，这些实用程序允许客户单独或集体定义执行所选保证的“会话”。 “会话”被广泛地定义为数据库的逻辑相关的读取和写入序列。 会话的启动和终止基本上独立于可能同时存在的其他会话。 但是，允许客户端克隆会话和/或与其他客户端合并会话。 客户从一组预定义的一致性保证中选择最小相关的担保子集，其中“相关性”是客户确定的因素。 在任何给定的时间，系统可能会执行许多不一致性保证的组合。 保证确保参与特定会话的所有客户都将数据库视为具有某些数据一致性的条件 - 其一致性仅针对参与者的读取和写入请求提供。 允许客户在会议过程中降级其选定的担保。 本发明的一个实现允许选择四个一致性保证中的任何一个。
