I define the attributes - manufacturer and manufacturer_part_number. A
better way would be to define an internal part number that could map
to multiple manufacturer/manufacturer_part_number tuples. An internal
part number database is on my to-do list.

I would not define a vendor field in the schematic. You do not want
your schematic to change if you change vendors.

For specs (other than value) that you want to display on the schematic
I would probably do attributes like spec_voltage, spec_power, etc.
If you do not want to display them on the schematic I would not add
them. You could get them from a component specs database keyed off of
an internal part number. If you only have a few specifications that
need to be displayed on the schematic I would probably just do text strings.
