The computation process that produces observed properties from its input data.
Input data may be an acquisition or some other computatation, not listed here yet. TODO: add input specification
Each newly computed observed property that this computation can produce is defined as its *capability*.
The list of capabilities is all-inclusive, even though not every computation can engage all capabilities.
