DeepFS – Implementing filesystems using semi-structured database technology

Primary goal is to find ways to enhance/combine the data storage and query capabilities of operating systems using semi-structured database technology.

DeepFS provides means to query the data stored in filesystems using standardized database query languages, namely XPath/XQuery. By storing the filesystem inside the BaseX database system and mounting the database instance as filesystem in userspace we present the feasibility of the approach.

DeepFS: XQuery Your Filesystem - Enhancing filesystems using semi-structured database technology


Project description:

The long term perspective of DeepFS is to find synergies between file system and semi-structured database techniques.
While file systems provide an easy and well-understood interface to the data, they lack important and demanded features like, for example, the ability to query the data.
DeepFS breaks with the long tradition to consider a file merely as a sequences of bytes. It unseals the black-box and lets the classical file hierarchy emerge into the files itself. The consideration of content and structure opens the door for query languages that operate on semi-structured data.
Currently we are following the concept of a joint storage for both, database and (a user level implementation) of DeepFS.
Finally DeepFS will provide both, proven and stable access to the data leveraging file system techniques and query support for all stored files.
