  During the last decade there has been a huge interest in Grid technologies,
and numerous Grid projects have been initiated with various visions of the
Grid. While all these visions have the same goal of resource sharing, they
differ in the functionality that a Grid supports, the grid characterisation,
programming environments, etc. In this paper we present a new Grid system
dedicated to deal with data issues, called DGET (Data Grid Environment and
Tools). DGET is characterized by its peer-to-peer communication system and
entity-based architecture, therefore, taking advantage of the main
functionality of both systems; P2P and Grid. DGET is currently under
development and a prototype implementing the main components is in its first
phase of testing. In this paper we limit our description to the system
architectural features and to the main differences with other systems.
