Architecture & Implementation of a Testbeds Repository

Federations of testbeds have an intrinsic characteristic: they are composed of heterogeneous resources and services residing in different geographic locations. To support description of these resources, there is a need for a common repository to be made available to the overall Panlab testbed federation architecture. In creating and integrating this repository, a number of design decisions were made to produce a flexible solution. We describe the structure of the repository software architecture and discuss the information model and derived data model. Finally, implementation details are further described at a functional level based on observations during the work carried out.
