传统文件系统为文件相互关系和其他提供上下文的元数据的有意义表示提供了薄弱且不充分的结构。将附加的面向文件的元数据存储在数据库、磁盘或两者中的现有设计受到它们所依赖的技术的限制。此外，它们不提供用户定义的文件之间的关系。为了解决这些问题，我们创建了链接文件系统 (LiFS)，这是一种文件系统设计，其中文件可以具有任意用户或应用程序指定的属性以及文件之间的属性链接。为了确保访问链接和属性时的性能，系统设计为将元数据存储在非易失性存储器中。本文讨论了利用这种方法的几个用例，并描述了我们为测试所提出的概念而开发的用户空间原型。
Traditional file systems provide a weak and inadequate structure for meaningful representations of file interrelationships and other context-providing metadata. Existing designs, which store additional file-oriented metadata either in a database, on disk, or both are limited by the technologies upon which they depend. Moreover, they do not provide for user-defined relationships among files. To address these issues, we created the linking file system (LiFS), a file system design in which files may have both arbitrary user- or application-specified attributes, and attributed links between files. In order to assure performance when accessing links and attributes, the system is designed to store metadata in non-volatile memory. This paper discusses several use cases that take advantage of this approach and describes the user-space prototype we developed to test the concepts presented.
