SMM12 — SMM confuses "To" and "From"

SMM confuses "To" and "From". There are two points of inconvenience (or even confusion ?) related to measure(ment) relationship: 1) Consider RescaledMeasure(ment) ("RSC") on one hand and BinaryMeasure(ment) ("BIN"), CollectiveMeasure(ment) ("COL"), RankingMeasure(ment) ("RNK") and GradeMeasure(ment) ("GRD") on the other hand. They all aggregate "from" a DimensionalMeasure(ment) ("DIM"). However, RSC looks to DIM as "from", whereas BIN, COL, RNK and GRD all look at DIM as "to". Isn't that confusing ? Is it inconsistent ? Or is there a good reason for it ? 2) When I think of aggregating from DIM (regardless of whether I do that by rescaling, or binary functor or accumulation or grading or ranking), I always think of aggregating "from" a DIM and "to" an aggregated one (RSC, BIN, COL, RNK, GRD). The “from” association of all SmmRelationship is defined as the origin element and the “to” association is defined as the target element which implies that the associations between BIN, COL, RNK and GRD to DIM are backwards. The “from” should in each case be the DIM measure(ment)s and the “to” should be the aggregating measure(ment)s.

Defer changes of "To" and "From" in MeasureRelationships

Further discussion learned that there might be good reasons why SMM 1.0 did it the way it was done, and that the deviating “from/to” naming of RescaledMeasure maybe on purpose. As the final conclusion of this was not reached yet, and as changing this would have quite some impact, it was decided to defer to issue.
