The resource oriented authorization manager (ROAM)

The resource oriented authorization manager (ROAM) was created to provide a simple but flexible authorization system for the National Fusion Grid (FusionGrid). This system builds on and extends previous community efforts by both responding to access authorization requests and by providing a Web interface/or resource management. ROAM works with the globus resource allocation manager (GRAM), and is general enough to be used by other virtual organizations that use Globus middleware or X.509/TLS authentication schemes to secure a grid of distributed resources.
