High Energy Physics experiments start using a Web Service style application to access functionality of their main frameworks. Those frameworks, however, are not ready to be executed in a standard Web Service environment as frameworks are too complex, monolithic and use non-standard and non-portable technologies. ATLAS Tag Browser is one of those Web Service. To provide the possibility to extract full ATLAS events from the standard Web Service, we need to access to full ATLAS offline framework - Athena. As Athena cannot run directly within any Web Service, the client server approach has been chosen. Web Service calls Athena remotely over XML-RPC connection using Athenaeum framework.
The paper will discuss integration of Athenaeum framework with ATLAS Tag database service, its distributed deployment, monitoring and performance.
