For the various tools and frameworks developed in the BOEMIE project  
to be integrated into a prototype, a state-of-the-art open  
architecture is required. It must be able to support the  
bootstrapping process and related prototype use cases as well as  
allow for straightforward integration with existing systems of  
professional users. Based on web services, this document 
specifies an  
appropriate architecture for the development of the two prototypes.
