Part 2: project description
The first part of our work consisted in the search of software documentation to manage files inside a PC. Our inspirations were:
- Google Desktop;
- Apple Spotlight;
Finally the second part of the work was the realization of our personal opinion maturated by such a study.
We firstly focused on requirements and design of our application.
Then we designed our ontology which is available here.
The library has two interesting characteristics: the ontology is made persistent and available to many programs concurrently through a relational database; the method to add files to the ontology has an architecture which permits automatic recognition of classes and relationship to add specific information to the knowledge base (actually only for PDF files but the core is easily extensible).
The Web Application is mainly a browser which also permits the editing of some file properties.
