The traditional file system is an integral part of how users interact with their desktop computers: to a great extent, user content (e.g. business documents, holiday pictures, project plans, etc.) is stored in a more or less unstructured manner. In the file system, this content is organized only using hierarchical directories and file names, which lack advanced expressivity in comparison to ontology-based classification schemes. As a result, traditional file systems do not provide sufficient means for organizing and annotating such content, especially when multiple users access the same file inventory.
