Hi Pieter,
"But why would I need a function to calculate a score that is just a
sum of a number of values, instead of a few +-operators?"
It is an open question but one advantage of using the function
approach, with simple values is that it can encapsulate the algorithm
without too much dependency on understanding openEHR paths or path
-bindings. That should allow broader engagement with non-openEHR
specialists.
My preference is to support use of openEHR datatypes within the
expression (albeit perhaps in reduced format), as otherwise passing
units etc as scalars starts to get cumbersome.
agree - that is the idea of this construct in the EL
*use_model*
org.openehr.rm
then you can declare vars to be of RM types like DvQuantity, DvOrdinal etc.
