[Mged-mage] Indexes into the BioDataCube

[Valerie W. <val...@sr...>]

Hi Folks, thanks for all your recent assistance!  Our MAGE loader for 
the BioWarehouse is nearly complete.

Another question though:  I want to confirm my understanding of the 
BioDataCube structure.  The type is defined as "any [][][]".  My 
understanding is that for each QuantitationType (Q), that Q will define 
what data type the "any" is via its "dataType" association to 
OntologyEntry. Also, the three indexes (B, D, and Q) to the cube can be 
in any order and are specified by the "order" attribute of BioDataCube.

My question is this: given a specific data value, say cube[0][1][2] and 
an order "BDQ", how does one back out the specific information for that 
B, D, and Q?  Is it literally interpreted as (assuming zero-based lists) 
"the first B, the second D, and the third Q" listed in the MAGE-ML?  Or 
is there some other mechanism for pulling out which B, D, and Q a 
particular data point is associated with?

Thanks much,
Valerie
