Do we have only statement? Or do we need to add in external objects?

Wednesday

This is a parking lot item. It is two new objects I would like to add at the "content level" to Measurement. Measurement would have 0..1 State and 0..1 Protocol. What is a state? What is this "protocol"? They are elements of an openEHR object called archetype. See https://www.dropbox.com/s/4y074kt3572k1vi/state.jpg?dl=0

Booz Allen in its VA Health and CMS work and Sam here from CDISC have adopted archetypes as the de facto "data element" for measurements now. That is, State and Protocol are used to extend data elements.

Think of our  micro-array use case for instrument right now.  Here is the current state of instrument: http://lion.ddialliance.org/package/newobjectsforsimpleinstrument. Yesterday we were able to talk about the manufacturers of each micro-array in our use case in which there was one "conceptual" instrument and two "implemented" instruments by pulling in a machine agent from the process model and describing some of her properties.

Arguably the standard way is with Protocol. One property of Protocol is the Method. Each micro-array manufacturer has her own method. Furthermore, Protocol can grow to handle Formula. Think of a virtual micro-array. Someone like BAH or another group has built it. It is actually a derived variable. It gets it data from a formula. The formula is how we translate the results of the different methods (manufacturers) into a single yardstick – one SNP fits all. See http://en.wikipedia.org/wiki/Single-nucleotide_polymorphism.

Leaving this second example aside which is perhaps a use case we might give more thought to in the context of provenance, were we to have a Protocol attached to a Measurement, the first example with two manufacturers is straightforward.
