Description (last modified by lawrence) (diff)

In the old days (i.e MOLES 1), we had data production tools including codes, and observation stations, inclusive of computers. The new moles is a bit more sophisticated than that.

Metafor has immature concepts of observations (left hand side of the diagram below), but mature concepts of numerical activities (right hand side, eg simulation etc). We should be thinking about how these fit in. I suspect we might have some of them alongside deployment as specialisation of MI_Operation.

The trunk metafor activity is  here

This is what it looked like at rev 360:

The decision that MOLES should specialize ISO 19115-2 means that we accept a basic distinction between acquisition and processing. Acquisition starts with a physical stimulus, while the inputs to processing (including simulations) are numerical boundary conditions, constraints etc. No physical stimulus.

ISO 19115 leaves 'processing' in data-quality/lineage, but creates a whole new set of classes to support the description of data acquisition operations.

MO_Computation is logically a specialization of LE/LI_ProcessStep.
Note that the difference between the latter two is that LE_ProcessStep has an _output_ as well as source data!
