Which license to use?

Matthew, thanks this is very helpful.

Just one more question, if the holder of the company remains the owner of the copyright (and basically license others to certain rights including obligations), would this mean that the rules set out in the license agreement don't apply to the holder of the copyright. To give an example: if I choose a license that states that all versions of the software should remain open source, would I then be able to create a version that is not open source?

That's understandable.  The OSI has been (vaguely) trying to correct this.

Great.  Almost every open source license requires that the copyright
notice is maintained, so they will never be denied credit.  Now, you
need to think about other criteria.

Do you want all interactive versions of the program to display some form
of attribution?

Consider the GPL and the Attribution Assurance License.

Do you want all versions of the program to remain open source?

Consider the GPL, Common Public License, etc..

Do you want to allow the program to be incorporated into proprietary

Consider the MIT License, New BSD license, etc.

OSI-approved (and free) software.  Even if the software is licensed
under an OSI-approved license, you may not use the certification mark if
any part of the software does not have published source.
