Practice for consistent attribute specification names or for populating
specification attributes?

I have not had to populate a schematic with component specs (other than value)
but I have setup Postgres tables with component specifications. For
each type of device
I pick column names that match specification names. So far I have been using
abbreviations (Vr, Vf, etc) rather than the full names. If I were to add these
specifications to a schematic I would probably add a prefix to
identify a specification --- maybe S.Vf or S_Vf or Spec.Vf

To automate the population of attributes I would set up a series of rules
that would query from the database and update the component attribute block
in the schematic. I do this for footprints now but other attributes could be
done. If a footprint attribute is not defined I run through a series of rules.
The first rule that passes determines the footprint attribute.
