This is fascinating part of the discussion. However, I'd like to hold off for a moment asking further clarification here, because my biggest question can be answered without really going into the details of defining these terms. See bellow. >> Do you think that ALv2 header the way it is written implies re-licensing >> or sublicensing? >> > > Sublicensing. > > "2. Grant of Copyright License.

Right. But you're not quoting the ALv2 header, you're quoting the license itself. IOW, if I were to put a full text of the ALv2 in the header preceding my MIT license header in the source code that would be fine and I have no problem with that. It also would be, however, inconvenient given the size of the full ALv2 text. So back to my question see bellow: >> To illustrate the difference lets take the most liberal license of all (MIT). >> There's nothing preventing sublicensing OR re-licensing in the text of the >> license itself, but at the same time the FAQ makes it pretty clear that one >> is allowed and the other one is not: >> http://www.tawesoft.co.uk/kb/article/mit-license-faq >> > > Like the Apache License, the MIT license explicitly grants permission > to sublicense: > > "... including without limitation the rights to use, copy, modify, > merge, publish, distribute, sublicense, and/or sell copies of the > Software ..." > > I don't believe they need to explicitly specify that they do not grant > permission to re-license the software.

Ok. That one I can readily agree on without further clarification of the terms. Which means that we're back to my original question -- there are two ASF-sanctioned texts that I know of. One is the ALv2 license itself. The other one is the text of the ALv2 header. Neither seem to be appropriate in the situation I'm describing (the former because it is just way too long, the later because it implied things that are not true "Licensed to..."). So the question really is, should we have a 3d ASF-sanctioned text along the lines of: ========================================================== The ASF sublicenses this file to you under the Apache License, Version 2.0 (the "License"); you may not use this file except in compliance with the License. You may obtain a copy of the License at http://www.apache.org/licenses/LICENSE-2.0 Unless required by applicable law or agreed to in writing, software distributed under the License is distributed on an "AS IS" BASIS, WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. See the License for the specific language governing permissions and limitations under the License. ========================================================== That seems to be the only way to really achieve what we're after here.
