Platform Services

From SPACE Wiki

The term Platform Services refers to a concept of a service-oriented middleware in which each constituent component is itself a (distributable/tradeable) web service. SPACE consists mostly of such services. This opens up the possibility to use the platform service interfaces as extension points of the platform.
