The scope of the data dictionary was determined to a great extent by matching this to the contents of ASAP2 . This affects above all:
 
<sw-variable>
 
<sw-param>
 
and the introduction of <sw-compu-method>.
The following table shows the terms used for ASAP and the MSR equivalents.

Cross-reference of ASAP and MSR terms
ASAP
MSR
characteristics
Parameters (<sw-param>)
measurement
Variable (<sw-variable>)
compu-method
Conversion formula (<sw-compu-method>)
The element names are selected on the basis of the terms used in MSR so as to prevent overlapping with MSR element names already in existence (Characteristic, Measurement). Parameters (<sw-param>), variable (<sw-variable>). <sw-compu-method> is used for the conversion formula.
