The ARDA Team
The ARDA project was started in April 2004 to support the four LHC experiments (ALICE, ATLAS, CMS and LHCb) in the implementation of individual production and analysis environments based on the EGEE middleware. The main goal of the project is to allow a fast feedback between the experiment and the middleware development teams via the construction and the usage of end-to-end prototypes allowing users to perform analyses out of the present data sets from recent montecarlo productions. In this talk the project is presented with highlights of the first results and lessons learnt so far. The relations of the project with similar initiatives within and outside the High Energy Physics community are reviewed (notably in the EGEE application identification and support).
