Keywords: science gateway, grid portal, e-collaboration, e-science, grid computing, GENIUS, EnginFrame, Liferay.
Our approach is totally different from the one used in the past. We will not provide for any top down solution such as the GENIUS  portal but we are designing "bricks" for different uses and purposes. In other to grant access to the grid services and to enhance performance we provide some improvements regarding the portal architecture. A new component has then been introduced: the grid layer. As a result of the implementation developed by the SAGA project [4,5] , it will act as an abstraction level between the portal environment and the Grid infrastructure sites.
Currently we are developing robot [6,7] authentication application program interfaces (APIs) to make them SAGA compliant and to use it with other gLite SAGA adaptors. As mentioned in the paper this technology is being used in other European Projects such as DECIDE  (life science) and INDICATE  (cultural heritage) where our team is involved in developing other components. This is proof of how this technology can be useful in every scientific domain.
Future work will include other adaptors in order to support new middleware. We are working on other modules for other usage such as a visualization portlet that, together with a visual element, will allow users to consult three-dimensional images.
