    • A file system that does not conflate item lifetime with the item's inclusion in an organizational structure of the file system is described herein. In addition, the file system's organizational structure is not limited to directory trees, but instead may use any directed acyclic graph (DAG). Items, once stored into the file system, may be maintained until affirmatively deleted by a client of the file system, regardless of whether the item is part of a DAG or not. Items may be placed in file regions, which are conceptual workspaces for a client to control item lifetime and to organize items into any DAG structure of the user's choosing. Items may be concurrently stored in multiple DAGs, and each file region may have one or more independent DAGs. An item's placement in a DAG may also be used to govern file properties such as namespace, security, privacy, and read/write attributes.
    • 这里描述了不将项目生命周期与项目包含在文件系统的组织结构中的文件系统。 此外,文件系统的组织结构不限于目录树,而是可以使用任何有向无环图(DAG)。 一旦存储到文件系统中的项目可以被维护,直到由文件系统的客户端肯定地删除,而不管该项目是否是DAG的一部分。 项目可以放置在文件区域中,这些是客户端的概念工作区域,用于控制项目生命周期,并将项目组织到用户选择的任何DAG结构中。 项目可以同时存储在多个DAG中,并且每个文件区域可以具有一个或多个独立的DAG。 项目在DAG中的放置也可用于管理文件属性,例如命名空间,安全性,隐私和读/写属性。
