Versioning for the Haystack system

Abstract

In this thesis, the design and implementation of a repository for electronic information is presented. While designed with the Haystack system in mind, the repository can easily be used by anyone familiar with RDF. This repository performs the basic task of storing the information that the user collects, in addition to automatically performing several other tasks in an effort to make retrieving the information simple and efficient. The additional tasks involve the storing of when and why information enters the repository. The hope is that this additional data will help the user when searching their repository. A person's sense of time and data dependence is a strong organizing princple that can help them locate a file simply because they remember when or why they archived it, or perhaps when they used it last. This repository allows a user to narrow the search of their information space in regards to time and dependence.
