I'm not confident in my interpretation of Open Source Software Licenses... for example if I were to use large chunks of Open Office for my own project, add my own code and then redistribute commercially, what would my obligations be?
I'm reading from here: http://www.apache.org/licenses/LICENSE-2.0.html
As far as I can tell I must include the original license, annotate code where I have made modifications (I guess this would somehow include deletions, I only the word processor functionality - not the rest of the office suite)...
Am I able to keep my own IP as my own? If I make a chunk of code that works with the open office word processor would it also have to be open source?
Personally I don't really have a problem with making my code open, but I don't think this approach will fly with my employer.
So, in a nutshell, would it be ok to trim down the word processor to the bare bones required for my project and add my own (locked / not open source code) to add my own functionality and then sell that software?
Do others do this? Are there examples out there?
