Do you mean like Bell LaPadula when you say "classification" level? 

The NSA does research in this area as also promotes the research
of formal methods which you could model your system using Z or
VDM.

As far as custom metadata, perhaps you can get away with existing
attributes that would give you the model which you are looking for.
