Subject LGPL3 -> Category X confirmation
Date Fri, 08 May 2009 08:39:50 GMT
The recent JIRA issue asks what the status of LGPL3 is at the ASF.
Currently we list it as a Category X license along with LGPL2 with the
reason that:

"The LGPL is ineligible primarily due to the restrictions it places on
larger works"

Much as I'd love to say that LGPL is akin to CDDL/MPL/EPL (ie: a
category B aka binary only), it still contains such items. From
section 4 of LGPL 3:

"You may convey a Combined Work under terms of your choice that, taken

debugging such modifications, if you also do each of the following:"

Section 4d) also says that the user has to be able to replace the LGPL
jar with an alternative (nominally a modified version of the

[Must admit that I don't get section 5 - I think it says that you can
fork the LGPL library and relicense under a license of your choice, as

* A license that says you can't take away the right to modify.
* A license that says you can't take away the right to use a modified version.
* A license that says you have to be able to reverse engineer to debug
the modified version [this being the main one - 'reverse engineer'
implies an additional right on the combined work].
* Any of GPL3, which applies to LGPL3 unless overriden.
