Re: License List v1.2 wiki page created
Regarding the GPL / LGPL exceptions -- We formerly decided to treat each combination of license + exception as a separate license since the exception can change the terms materially. For instance GPL + Classpath is more permissive than LGPL. From a practical point of view, the exception creates a different license. Tomtoggle quoted messageShow quoted text

*Outstanding Issues/Questions:*We could just have a separate license for GPL+amendment for all the
common exceptions. This fits the current license model pretty well.
However, it means that an uncommon set of amendments would require a
custom license declaration in SPDX file.
Another approach that might be to have a LicenseAmendment concept and
allow a "composite" license to be defined as a base license plus a set
of amendments. This feasible but would require a bit of work in the
technical working group to nail down the specifics.
* How do we want to handle LGPL/GPL "vXor later" versus LGPL/GPL vX?I think this should not be handled at license level. There is no such
license as "GPL v2 or later". Rather, content is licensed under the
disjunctive set of all GPL licenses with a version greater than or equal
If licenses expressed their version relationships using dc:isVersionOf
and dc:replaces we could leverage that information. Using the version
relationships we could define a version based disjunctive license set.
This set would specify the minimum acceptable version of the license,
e.g. GPLv2. A license would be considered to be part of such a set if
it "replaces" and "isVersionOf", either directly or indirectly, the
minimum acceptable version.
* Licenses with an alternative name or an associated project inWe could quite easily support an arbitrary number of name for any
particular license. Perhaps that would be easier than trying to settle
on just one name for these licenses.
