A list of licences other than the Apache v1 and v2 licences, and whether they may be used by Jakarta (and other ASF projects by implication) sub-projects.

Work-around ideas

  1. A plugin architecture can get around this, however the plugins cannot be a part of the ASF in anyway. Also, the licensing of the plugins may be intricate. 2. Footnotes/disclaimers being added to the non-usable licences might allow us to use them. 3. Ask the maintainer of the library to dual-license under an acceptable license.

Comments

HowardLewisShip: I was under the impression that the ASF forbade downloading any code that did not originate within the ASF. I wish I had a reference. Tapestry and HiveMind download all their dependencies from the Maven repository. I'd also love to see an explicit clarification about Hibernate and its wacky license since Hibernate integration examples are probably the #1 demand from both the Tapestry and HiveMind communities.
