[Role] (Application / Enabler) Service Aggregators [Description] 
Service Aggregators select Services from a broad variety of Service Providers and compose them to build new service offerings that address the specific requirements of niche End Users. (Application / Enabler) Service Brokers bring together a multitude of Services from diverse Providers and publish them on marketplaces where end users can compare them, matching their requirements with capabilities of published Services - they should exploit economies of scale and protect investments in the long run. Finally, the ability to combine applications from different sources necessitates innovative revenue sharing models across partners and potentially also customers (e.g. crowd-sourcing) which have to be adapted dynamically as market conditions change.
