    摘要： Described herein is using type information with a graph of nodes and predicates, in which the type information may be used to determine validity of (type check) a query to be executed against the graph. In one aspect, each node has a type, and each predicate indicates a valid relationship between two types of nodes. A type checking mechanism uses the type information to determine whether a query is valid, which may be the entire query prior to query processing/compilation time, or as the query is being composed by a user. One or more valid predicates for a given node may be discovered based upon the node type, such as discovered to assist the user during query composition. Also described is using the type information to optimize the query.

    摘要： The present invention provides a novel client side caching (CSC) infrastructure that supports transition states at the directory level to facilitate a seamless operation across connectivity states between client and remote server. More specifically, persistent caching is performed to safeguard the user (e.g., client) and/or the client applications across connectivity interruptions and/or bandwidth changes. This is accomplished in part by caching to a client data store the desirable file(s) together with the appropriate file access parameters. Moreover, the client maintains access to cached files during periods of disconnect. Furthermore, portions of a path can be offline while other portions upstream can remain online. CSC operates on the logical path which cooperates with DFS which operates on the physical path to keep track of files cached, accessed and changes in the directories. In addition, truth on the client is facilitated whether or not a conflict of file copies exists.

    摘要翻译： 本发明提供了一种新颖的客户端缓存（CSC）基础设施，其支持目录级别的转换状态，以促进跨客户端和远程服务器之间的连接状态的无缝操作。 更具体地，执行持续高速缓存以跨连接中断和/或带宽改变来保护用户（例如，客户端）和/或客户端应用。 这部分是通过将客户端数据存储器连同适当的文件访问参数一起缓存所需的文件来实现的。 此外，客户端在断开连接期间保持对缓存文件的访问。 此外，路径的一部分可以离线，而上游的其他部分可以保持联机。 CSC在与物理路径上运行的DFS协作的逻辑路径上运行，以跟踪缓存，访问和更改目录中的文件。 此外，无论文件副本是否存在冲突，客户端上的真相都是有利的。

    摘要： Described is a system and method that synchronizes cached files and directories with a server's files and directories via a layered architecture, by collapsing state information into an index into a fixed set of known states, and looking up the action that synchronizes that state. The actions are then taken to synchronize the content. Any of fifty possible synchronization states are thus handled. A synchronization controller requests a subsystem to evaluate a local cache and remote file system to generate state flags for each item considered for synchronization. The synchronization controller processes the state information to identify a selected table from among a plurality of tables that contain the fifty values, and uses other flags to compute an index into the table. The selected table contains values that index into an action table containing actions that specify an operation set that is requested to synchronize the particular state scenario.
