    • In a computer including at least one client and at least one file system having an associated format, a system and method are provided for filtering requests for metadata from the client in a manner which is transparent to the client. An interface receives the client's request for metadata from the file system and forwards the request to a dispatcher. The dispatcher forwards the request to a format agent which fulfills the request. A third party filter system filters the requested metadata. If the filter system requires metadata to perform the filtering, the filter system requests additional metadata, and the format agent fulfills the client's request and the filter system's request. The format agent fulfills portions of the client's request and the filter system's request regarding metadata which is contained in the associated format of the file system directly from the file system. The format agent accesses a storage means to fulfill portions of the client's request and the filter system's request regarding metadata which is not included in the associated format of the file system. If the client's request is to write or modify metadata, the filter system filters metadata to be written or modified by the format agent. If the client's request is to retrieve metadata, the filter system filters metadata retrieved by the format agent. In this manner, third parties can modify metadata which is requested by a client from a file system or compute metadata based on the client's request without altering the format of the file system and can benefit from the modification and/or computation of such metadata by other parties.
    • 在包括至少一个客户端和至少一个具有关联格式的文件系统的计算机中,提供了一种用于以对客户端透明的方式从客户端过滤对元数据的请求的系统和方法。 接口从文件系统接收客户端对元数据的请求,并将请求转发给调度程序。 调度员将请求转发到满足请求的格式代理。 第三方过滤器系统过滤所请求的元数据。 如果过滤系统需要元数据来执行过滤,则过滤器系统将请求额外的元数据,格式代理会满足客户端的请求和过滤系统的请求。 格式代理直接从文件系统完成客户端请求的部分和过滤器系统关于包含在文件系统的关联格式中的元数据的请求。 格式代理访问存储装置以实现客户端请求的部分以及关于不包括在文件系统的相关格式中的元数据的过滤系统的请求。 如果客户端的请求是写入或修改元数据,则过滤器系统会过滤要由格式代理程序编写或修改的元数据。 如果客户端的请求是检索元数据,则过滤器系统将过滤由格式代理检索到的元数据。 以这种方式,第三方可以从文件系统修改由客户端请求的元数据或者基于客户端的请求来计算元数据而不改变文件系统的格式,并且可以受益于其他的这种元数据的修改和/或计算 派对。

    • A structure and technique is disclosed to allow passing control lines, conduits or cables of all sorts through a downhole tool. The assembly provides for passage of the conduit or cable through and into the bore of the downhole tool, protected by an internal carrier. The end connections are assembled without any twisting force applied to the cable or conduit. The end connections resist torque. A jam nut on either end provides one seal, and internal seals are used against the mandrel of the downhole tool to further provide pressure isolation where the cable or conduit enters the tool body or exits. Tensile loads are passed through the tool body rather than the cable or conduit. There is complete pressure isolation between the conduit and both the tubing and the annulus.
    • 公开了一种结构和技术,以允许通过井下工具通过各种控制线,导管或电缆。 组件提供导管或电缆通过并进入井下工具的孔,由内部载体保护。 端部连接被组装而没有施加到电缆或导管的任何扭转力。 端部连接抵抗扭矩。 两端的锁紧螺母提供一个密封,并且内部密封件用于井下工具的心轴,以进一步提供电缆或管道进入工具主体或出口的压力隔离。 拉伸载荷通过工具体而不是电缆或导管。 导管与管道和环之间完全隔离压力。
