Re: [epl-discuss] Next Round of Proposed Revisions to the EPL

Dear Mike,

Thanks for sharing this draft and allowing us to provide comments.

I have the following remarks:

The definition of "Modified Work" shifts the EPL from a strong copyleft to a
weak copyleft (at least to some people's interpretation). I think this is
intended and I suppose most people will be very happy with that change.

Whereas the changes in sec. 1 are fine, the new wording in sec. 2 could have
some unwanted side effects. The grant of rights should be as broad as
possible (as with all FOSS licenses). Using the term "Modified Work" instead
of "derivative work" could be interpreted in a way that alterations are not
allowed which are no "modifications" but create a "derivative work". Since
it is unclear in many (all?) jurisdictions what is considered a "derivative
work" we cannot assume that the current definition of "Modified Work" does
cover all alterations needing permission from the copyright holder.
Therefore, I suggest the following text: "prepare derivative works,
including but not limited to Modified Works,"

You might consider to clarify the meaning of sec. 3:
"a) it complies with the terms and conditions of this Agreement;"

I never understood what means "comply" in this provision. Does the own
license agreement contain all license conditions of the EPL?

Which license obligations have to be fulfiled in the case that the
Executable Code is distributed under the EPL (instead of an own license
agreement)? It would be great to facilitate license compliance by providing
a clear and simple list of all license obligations.

It might be useful to check the EPL for full license compatibility with the
Apache-2.0. I have concerns about compatibility if someone wants to copy
code from an Apache-2.0 program into EPL code (e.g. with regard to the
"NOTICE" provision of Apache-2.0).

Thanks all for your work and helping to improve the EPL.
