2. CERN - EGEE User Forum 2 Plateforme de Calcul pour les Sciences du Vivant March 1 st 2006 RUGBI: french project financed by the Gen'homme network: –Grid for biologists –Based on existing technologies (Web Services, globus toolkit 4, native XML databases) –3 sites in France: Grenoble, Lyon, Clermont-Ferrand Biologists are using, most of the time flat files databases, available on ftp repositories. These databases are changing and growing constantly and therefore need regular updates in order to keep the most up to date version available. This service, is an applicative service, integrable in a grid environment, which performs automatically regular updates and propagate them through the grid. Introduction

5. CERN - EGEE User Forum 5 Plateforme de Calcul pour les Sciences du Vivant March 1 st 2006 Main Steps of the process 1. The SER updates its repository and notifies the clients (Comparison + download) 2. The SE gets the notification and download the updates with GridFTP. 3.The SER ask for a REGISTER of the new database and an UNREGISTER of the old version. 4. The SE notifies the success of the deployment to the SER 5. The SER is waiting for a deletion notification of the old version, when it is received, it deletes the old database and propagates this notification through the grid.

The databases are described as dynamical XML sheets, containing all the necessary information to make each step of the process. The Data
