* How exactly are we handling all the GPL/LGPL exceptions?
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 to 2.

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 in
parenthesis after the name – some of these need a determination
and some may be superfluous, perhaps? Can we come up with a “rule”
for this?:
o See ISC License (Bind, DHCP Server)
o Lucent Public License v1.02 (Plan9)
o MIT (also X11)
o BSD licenses – currently include all naming variations “BSD
3-clause ‘New’ or ‘Revised’ License” à seems like we should
pick one naming protocol and stick with it, maybe putting
the others in parenthesis or omitting??
We 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.
