You say the Derby Apache OS license is "lite?" I'm confused by this. Or perhaps it's having a separate supported commercial version you are uncomfortable with. Why?
Compare to MySQL. MySQL uses a dual-license strategy.... there is a GPL version, but also a commercial license that you must use for commercial products distribution. Don't get me wrong, I'm not criticizing MySQL, and MySQL and Derby do different things well. But if you want to resell your MySQL-based product to customers, you need to pay them a fee, no? Sometimes a very big fee. And I seem to recall if you want to do ACID-compliant transactions, row-locking, so on you also need InnoDB. Again, to resell you have to buy a license... more money.
Not so with Derby... all of this is available for commercial distribution, without constraints of the need for additional licenses.
MySQL AG also maintains only *one code base* for MySQL server, and they run that code against a standard test suite. This is great, and smart IMHO. But my point... in view of their strategy, do you think MySQL is "lite"ing open source as well?

P.S. By way of full disclosure, I have been an IBM consultant in the past. All opinions are my own.

Probably so. That really just makes sense, and it seems to be a pretty standard model for companies looking to make money from code which is nominally "free." Release it to the world, let it develop as open-source, and then occassionally take a snap-shot of the code, do any clean-up / value-add stuff, and then release it as a commercial product. Of course the interesting thing is that anybody could do the exact same thing, even "Bob's Screen Door Repair and Relational Databases, LLC." So what IBM is really selling in a sense is their reputation (versus Bob, for example).
closed communities, seperate forks, its unteniable and results in something more resembling
"shared source". Plus its just damn confusing and makes for bad branding.
Of course this is my personal opinion only. -Andy
