[DDI-users] representing analyses in DDI

[Wendy Thomas]

Paul,

Missed the part about the PDF output. You can describe all but the 
physical location easily. In order to use PhysicalInstance you need a 
record layout is not something you may have with a PDF layout.

That's one we need to think about a bit. If its tabular you can describe 
it with the NCube tabular layout as it simply provides a column row 
coordinate...but that assumes NCube like results. Look at Proprietary and 
see if that will work for you...let me know what you decide. Alternatively 
I would attach the PDF with an OtherMaterial description in LogicalProduct 
and point it to either the logical product or if there are multiple PDFs 
set up variable groups with the variables from each PDF and then point to 
that. A bit of a work around but all I have right now for PDF output that 
is not NCube in nature.
