RECAST is a framework for extending the impact of existing analyses performed by high-energy physics experiments.

1. Anyone can add analyses to the Analysis Catalog
2. Anyone can upload alternative signals in the LHE format and request that any given analysis is "recast" for their alternative model (Note: this is a request, there is no obligation for the experiments to respond.)
3. Anyone can subscribe to an analysis to be informed of activity associated with the analysis
4. Experimentalists can accept the request, process these alternative signals with the full simulation, reconstruction, and analysis selection. If they are authorized by their collaboration, then they can respond with an authoritative result for the selection efficiency and cross-section limits for the alternative signal. Note, anyone can provide a non-authoritative result, for instance one based on fast simulation.
5. Anyone can view the results associated with a request.
