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.
