Define each "object" independently, except all objects have one
dimension in common.  There will be no formal "array of objects", but
you can access them automatically in a program, via an array of
variable names.

This is a simplistic view of what I think you requested.  Will this work?

dimensions:
  d = 30 ;
  nx = 5 ;
  ny = 7 ;
  nz = 11 ;
variables:
  float x(nx,d) ;
  float y(ny,d) ;
  float z(nz,d) ;
