Users of WS-PGRADE define their applications as workflows. They can share their applications using its internal repository solution. Hence users can import, parameterize and execute workflows developed by others. Using this idea, Application Specific Module (ASM) offers a Java API for all of these functionalities to develop Application Specific Portlets fitting to the end-users' needs and hiding all the complex mechanisms of the underlying system.
Science Gateways developed using ASM are listed at http://www.sci-bus.eu/science-gateways
