The Terracotta Public License makes the following changes to the Mozilla Public License, version 1.1:
(1) We eliminated the definition of "Commercial Use." This term was thought to be misleading, because Terracotta software can be distributed for both commercial and non-commercial purposes, and we didn't want anyone to see the definition and conclude that the license differentiates between commercial and non-commercial use. This modification to the MPL also appears in the OSI-approved Common Development and Distribution License (CDDL).
(2) We clarified that an individual can be a "Contributor." This modification to the MPL also appears in the CDDL.
(3) We clarified that a "Modification" includes any new file that is contributed or otherwise made available under the terms of the license.
(4) We expanded the definition of "Original Code" to cover both Source Code and Executables. This modification to the MPL also appears in the CDDL.
(5) Wherever software distribution is mentioned in the license, we added the phrase "or otherwise makes available," in order to cover passive types of distribution, such as with ASPs. This modification to the MPL also appears in the CDDL.
(6) As required by both the MPL and the CDDL, we stated that our license is similar to those licenses, and contains elements of each of them, as well as modifications.
(7) We clarified that the licensee is responsible for complying with export laws.
(8) We added an attribution requirement, which says that if a licensee redistributes Covered Code, they must include the phrase "Powered by Terracotta" in legible form at the bottom of any user interface screen. This type of modification to the MPL appears in numerous open-source licenses, including the Zimbra TM Public License, the Alfresco TM Public License, the MuleSource TM Public License, and the SugarCRM TM Public License.
