The document discusses the IMPACT Interoperability Framework (IIF), which allows various software components to work together. The IIF uses open source technologies like Java, Tomcat, and Axis2. It includes a generic web service wrapper that facilitates integration of new components. Workflows can be created in Taverna to combine components into processing pipelines. The workflows can be shared, executed, and monitored through various clients and repositories. The IIF supports scalability through an enterprise service bus and has been tested on a supercomputing cloud.
