Hello Wolfgang,
You jogged my memory concerning our discussion on this subject some time ago. You had given me a contact (James Casey) at CERN to discuss this subject further and I think the subject slipped off the radar at that point. Here was that old thread. I've cc'd him on this message to re-initialize discussion.

Mark, James:
Mark: James Casey at CERN is fluent in java / open source. I'm cc'ing him here.
James: On behalf of jakarta-commons-math, Mark would like to discuss if and how parts of colt could be relicensed under the ASF license so that commons can work from there. See
James, if you'd like to help Mark and the jakarta-commons folks out, please let him know what if anything could be done about relicensing and/or copyright transfers. See Marks suggestions to keep CERN's name and origin in there, somewhere.
I saw this come up on the jpackage list a week or so ago... I'd love to do what I can to help. I'll try and find the appropriate person in CERN legal for you to contact (We have some contacts from doing the EDG licence).

Hi, let me briefly introduce myself. I'm the author of Colt which has the BSD-style license you referred to below.
I encourage you to take code or ideas from Colt, as you see fit, and as you see compatible with Apache licensing policy.
I wrote this code some six years ago while working at CERN, so the copyright is not with me personally, but with CERN (http://www.cern.ch). I have left CERN some years ago to work for a Bay Area research lab, so I consider it unlikely that the license could be changed, and I'm not in a position to help change the license, even though I would support such a license change. In my judgement, you will have to decide if the current license works for you, or not. If it works for you, you are most welcome.
As far as Jama is concerned, the code is a straightforward adaption of the original Jama code, as explained on
http://dsd.lbl.gov/~hoschek/colt/api/cern/colt/matrix/linalg/package- summary.html#Overview
You could contact the Jama authors for licensing issues.
Hope this helps, Wolfgang.
I am posting this to the Licensing list as well because it is very unclear how to proceed and we dearly need their advice on this subject. Licensing, the issue has to do with policy for adding code from a external project, which the author has approved our usage of via email.

We would like to add certain fragments of the "Colt" API which is licensed under a BSD style licensing.

How do we properly proceed?

Colt contains a port of much of JAMA, IIRC, and as Wolfgang posted not too long
ago, Colt's new license is much more compatible with the Apache license. I'm
not sure if it's sufficiently compatible for us to start merging in code,
though.

I think we should clarify our own position given his approval.
1.) I think the appropriate path is to discuss with Wolfgang and our Licensing list what is required to meet any ASF requirements that may exist. Licensing needs to clarify how we should proceed.
The challenge is what to do about any ASF polices concerning licensing adjustments, for which none of us are "knowledgeable".
2.) I think this is a exception to our policy of acknowledging authorship in the project documentation and not in the code. In this case I think we should attempt to maintain significant references to his project as the original source of any codebase additions added to the Commons math API.
3.) If ASF requires more stringent approval in writing, we request more formally to have Wolfgang fax in some sort of donation form to ASF.
