If a distribute a access database/program as
a .mdb, does it qualify as open source?
The .MDB file format does not _imply_ Open Source or any other category of
use.
Open Source is a type of license to use something (there are several
licenses classed as "open source" with somewhat different terms and
conditions), and you can legally put as many or as few limits on the user of
an Access database that is your original work as you wish. An .MDB can be
licensed as everything from Public Domain (which anyone is free to use as
their own in any way they desire) to very stringent Terms and Conditions,
with Access or other security used to help enforce them.
For details on intellectual property, and protection of it, you should
consult an attorney in your jurisdiction who specializes in intellectual
property, patent, and copyright law.
