Red Hat has decided that it fits in their "MIT" pigeonhole better than it fits in their "BSD" pigeonhole. If you compare the OSI definitions of these licenses: http://www.opensource.org/licenses/bsd-license.php http://www.opensource.org/licenses/mit-license.php our wording is not a terribly exact match to either, but RH's lawyers think it's closer to MIT. The key point is that they consider "BSD" to include the no-endorsement clause and possibly the advertising clause, and we have neither. OSI uses the phrase "simplified BSD" to refer to BSD-derived licenses without either of those two clauses. Red Hat has decided to call them MIT instead. As best I can tell there's no really important distinction between simplified BSD terms and MIT terms, so there is not a lot of point in arguing which one ours is. If anyone comes up to you and starts asking questions about two-clause vs three-clause vs four-clause BSD, the answer is that we use the most liberal variant. Otherwise I'm not sure it matters. regards, tom lane -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
