SGW-05: Science Gateways Resource Information Management

Executive Summary: 
Science gateway developers need a standard mechanism for accessing detailed information about XSEDE compute resources--such as available queues and queue policies--in order to efficiently use the resources.
User Importance Summary: 
The capabilities, limitations, and use policies of XSEDE compute resources differ greatly throughout the suite of resources. In order to use these resources efficiently, each gateway compiles and saves this information statically for their own use, obtaining the information in ad hoc ways. It would be better if XSEDE provided this information for each compute system in a standard way and made it easily available for all gateways to access.
Target Communities and Sizes:
