[DDI-ADG] need help clarifying descriptions

[Ilona Einowski]

Wendy - after you left the call yesterday we had much discussion on these
two elements:
 
 
 
 
dimensionReference - Row 20 
identifies the dimensionVariable describing this dimension	
 
 
 
 
 
variableReference - Row 21
 
identifies the dimensionVariable describing this dimension	
 
 
 
The new descriptions I attempted were as follows
 
dimensionReference - Row 20 
 
indicates the name of the variable to be used as one of the coordinates of
the nCube e.g. gender (GENDER1), or age (AGE), or party affiliation
(PARTYID) .  I'm not sure if this note should be here describing
dimensionReference or if it belong in Row 21 to describe dimensionVariable
and this Row 20 should say "unique name for this particular dimension of
this variable" 	
 
variableReference - Row 21
 
 

see note above for Row 20.     
0r is it: identifies the variable in the file describing this dimension in
the special cases where the catValu (Section 4 Variable 4.3.18.1)  provides
the field content and the labl (Section 4 Variable 4.3.18.2) provides the
code because in the file there is a physical record for each reported value
of the variable for example,  in County Business Patterns there is a
variable for Industry Code 
 
In current Scheme it is defined as:  an IDREF that points to the variable
that makes up this dimension of the nCube.           
 
I promised the group I would forward this to you and see if you could
untangle it for us.
 
Please reply all so we can all get on the same page ASAP.
 
Thanks!
 
Ilona
