Dear all,

We currently consider the use of the APL license (ALFRESCO PUBLIC
LICENSE) initiated by www.Alfresco.com as a license based on MPL1.1.

APL contains the attached (below) Exhibit B. I have three questions if I may:
a) Could you please let us know if such Exhibit B is compliant with MPL1.1?
b) Is APL a valid Open Source license (I cannot find any reference in
c) Can a Contributor force the User of an Open Source license to
display such a message on each and every screen of all his GUIs?
Wouldn't it be enough to refer to it in the Source Code and in the
About box?

thanks for your time,
