OSMOSIS-RFID: Semantic File System to Incorporate Real Objects into the Virtual World OSMOSIS-RFID: Sistema de Ficheiros Semântico para Incorporar Objectos Reais no Mundo Virtual

With the increasing storage capacity of computers, it became evident that the use of a hierarchical le system no longer ts the interests of the user, i.e., with this kind of le system the user cannot nd a le in an easy, quick and intuitive way. For this reason, the concept of Semantic File System became quite popular. This is a system for storing and organizing information, that allows associations between attributes and les and then searching those les using attributes (or keywords). All the limitations of hierarchical systems led us to the development of OSMOSIS. This is a semantic le system with the ability to integrate physical objects in the virtual world. OSMOSIS can be divided into two major parts. The rst (OSMOSIS-SFS) is a semantic le system that can associate, with les, attributes extracted from its properties and contents, can explicitly relate two les, and allows users to manually apply a Tag to a le. The second part (OSMOSIS-RFID) is the integration of the semantic system into the real world. In other words, with this system it will be possible to attach RFID Tags to physical locations (e.g. living room) or physical objects, related to virtual les (e.g. photo album) and then use that information to nd physical objects, or to anticipate what les the user may want to see, based on his/hers physical location.
