  Possible EOSDIS interest: Cloud analytics, MAAP (?)

  "The Application Package (AP) serves as a means to convey different kinds of information describing a certain application - often, but not necessarily, an Earth Observation data processing algorithm - so that different elements of an ecosystem generically known as an Exploitation Platform can exchange information among themselves in a standard and interoperable way. The AP guarantees that, despite potentially very heterogeneous implementations and implementing entities, applications are treated equally. The AP also guarantees that the Earth Observation scientist who developed it on the one hand is shielded from infrastructure details and heterogeneity and on the other hand benefits from the ability to execute the same application on different infrastructure."
