You might find the following paper on the "field" data-model helpful:
Haber, R., B. Lucas and N. Collins. "A Data Model for Scientific
Visualization with Provisions for Regular and Irregular Grids",
Proceedings IEEE Visualization '91, pp. 298-305, October 1991.
I'm investigating the feasibility of emulating this data model in
a netCDF context.
