You may want to specify lowercase. If someone configures their database for
case sensitive and uses the attribute name as a column name they could get
an error.
You could still treat names as case insensitive for your webserver.

P.S. One of the reasons I do not like to add vendor part number
information to the
schematic is that sometimes there is a one-to-many relationship between the
manufacturer/manufacturer_part_number and the vendor/vendor_part_number.
For example ----
A Yageo resistor with part number RC0805FR-071KL from Digikey
is 311-1.00KCRCT-ND in cut tape and 311-1.00KCRTR-ND in tape and reel.
No change to the Yageo part number to specifiy packaging. Some manufacturers
have a packaging suffix others don't.
