Peter Moldave (lawyer) is going to cover a few more licenses - Artistic, intel, MIT, NASA, PHP. These cover 4% of the licenses used on SourceForge (as opposed to 80% for the GPL/LGPL).
MIT, Intel, PHP - like BSD
Artistic, NASA - unique, some MPL like properties
All of these are OSI compliant (Artistic 2.0 is not listed). The NASA one merely adds language about export law (US). The MIT, Intel, and Artistic 2.0 are "GPL compatible". PHP is "free" but not "GPL compatible". Compatible here means that code under a GPL compatible license may be used in a GPL licensed project.
MIT, Intel, PHP - all simple. The Artistic and NASA licenses are complicated. MIT, Intel, PHP - no substantial restrictions imposed. Artistic - modified source need not be distributed if standard source is available. NASA - restrictive, modified source must be distributed. With all of these licenses, larger works are allowable - no restrictions.
MIT, Intel, PHP - no pricing constraints. Artistic:
- Can't charge for the code
- Can only charge a reasonable copying fee
- Can charge for support
- Can charge for larger work
NASA - source code must be freely available, not clear beyond that. Then there's patent treatments - other than NASA license, all of these are silent. NASA license has a specific grant of patent rights. The treatment of combination patents and modifications specified. Peter's take here - he's yet to see an OSS license that goes over patent rights in a helpful way. Only the NASA license requires any kind of warranty - the rest simply disclaim. What about output use (i.e., is the output of a compiler a "derivative work? What about a parser?). The Artistic and NASA licenses attempt to address, but get to technically specific (Artistic speaks explicitly about C and Perl routines - go figure).
All of these provide specifics on internal/external use, and opening of derived works. What about utility (i.e., do we actually need them?) - MIT, PHP, Intel - no real difference from the BSD. Artistic: 1.0 Unclear, and the V2.0 gets a lot closer to the GPL or perhaps the MPL. NASA - long and complex.
