Description

AMI is an application which stores and allows access to dataset metadata for the ATLAS experiment. It provides a set of generic tools for managing database applications. It has a three-tier architecture with a core that supports a connection to any RDBMS using JDBC and SQL. The middle layer assumes that the databases have an AMI compliant self-describing structure. It provides a generic web interface and a generic command line interface. A Virtual Organisation Membership Service (VOMS) is an authorisation system for Virtual Organisations (VO's). The ATLAS VO has a VOMS system which contains its own authorisation information. This presentation provides an account of the development of a Java based solution to integrate the ATLAS VOMS system to the ATLAS Metadata Interface (AMI). The prerequisites authentication and authorisation demand on grid architecture are explained. The current workings of a VOMS system and the resulting requirements this has on a client of this system are discussed. We explore possible solutions to these requirements before detailing the mechanism behind the chosen solution and how it was integrated with the AMI framework.

Summary

This presentation provides an account of the development of a Java based solution to
integrate
the ATLAS VOMS system to the ATLAS Metadata Interface (AMI). The prerequisites
authentication and authorisation demand on grid architecture are explained. The current
workings of a VOMS system and the resulting requirements this has on a client of this
system
are discussed. We explore possible solutions to these requirements before detailing the
mechanism behind the chosen solution and how it was integrated with the AMI framework.
