Abstract

Access control has evolved in file systems. Early access control was limited and didn't handle identities. Access control then shifted to develop concepts such as identities. The next progression was the ability to take these identities and use lists to control what those identities can do. At this point we start to see more areas implementing access control such as web information systems. Web information systems has themselves started to raise the profile of semantic information. As semantic information systems start to expand new opportunities in access control become available to be explored. This dissertation introduces an experimental file system. The file system explores the concept of utilising metadata in a file system. The metadata is supported through the use of a database system. The introduction of the database enables the use of features such as views within the file system. Databases also provide a rich query language to utilise when nding information. The database aides the development of semantic meaning for the metadata stored. This provides greater meaning to the metadata and enables a platform for rethinking access control
