[Jts-topo-suite-user] A major step along the road to LocationTech

I just spent a productive few days in a code sprint with a great crew of
LocationTech devs. A key objective was to get the JTS codebase buffed up
for submission to its LocationTech project [1]. Check out the
work-in-progress on GitHub [2].

In particular, note that the license has now changed to BSD + EPL.

It's great to see JTS reach this milestone Martin. Thanks for your
efforts, and for the help of the others at LocationTech that assisted.

Dear Martin,

Is this license compatible with GPL 3 ?

Hmmm, this is (as usual with these crazy legal things) a tricky issue.
According to [1] BSD3 is compatible with GPL3, but EPL is not. But I don't
whether this ultimately leaves JTS compatible or not. I will inquire and
report back (the benefit of having the LocationTecH legal team on call!)

The dual license amounts to BSD so we can work with everyone, and EPL if
you are concerned about patents.

When using the code you can choose which of the two licenses your
organization finds appropriate.

Dear Everyone,

On behalf of LocationTech & it's parent the Eclipse Foundation, just
confirming what Jody has written.

The re-licensing & move to git is a really great thing. Thanks again to
Martin, Jody, Jim, Rob, and others who made it happen over the last few
days.

Also, I am especially thrilled to see 3 new committers added to the JTS
project. Congratulations to all.

The Foundation's legal team will be formally reviewing the code &
working with Martin & the team to be able to give it a clean bill of
health soon.

Cheers!

Andrea

The two BSD licenses are the same BSD3 license - they are just there
because there are two copyrights on different files. I don't think this
affects any licensing questions.

The issue of AND vs OR does seem like it needs clarification, at least on
this list. Is it possible that in legalese AND actually implies OR?
Somehow I don't think law works under strict Boolean logic. @jody, any
comments?

Post by Sandro Santilli

The comment on top of some files do not clearly state this.
All rights reserved. This program and the accompanying materials
are made available under the terms of the Eclipse Public License v1.0
(http://www.eclipse.org/legal/epl-v10.html), and the Vivid Solutions BSD
License v1.0 (found at the root of the repository).
So it says EPL _and_ BSD, rather than EPL _or_ BSD.
Also, it is not clear which BSD license is being used as the root has
two different LICENSE*BSD.txt files [2]

I think copyright ownership (and applied license) should be advertised
in each file, while the external file should be referenced by the each
source file for further details.

Not sure I follow. The files have been updated to indicate the licenses.
What do you think they should say?

What they say now is ok, about copyright ownership:

* Copyright (C) 2016 Vivid Solutions

About applied license there's the AND issue (this is about the
single file, not the whole project, so either one or another
license is likely to apply):

* All rights reserved. This program and the accompanying materials
* are made available under the terms of the Eclipse Public License v1.0
* (http://www.eclipse.org/legal/epl-v10.html), and the Vivid Solutions BSD
* License v1.0 (found at the root of the repository).

Then, the LICENSE* files on the root should just contain the license,
with eventual copyright ownership of the license itself, but not copyright
ownership of the code it applies to.

LICENSE_VSI_BSD3.txt is weird in thi reguard because it starts with
"Copyright (c) 2016, Vivid Solutions Inc." which would likely mean
"Vivid Solutions" has copyright over the BSD3 license text, which is
unlikely. Same with LICENSE_MDAVIS_BSD3.txt. I think it should just
be LICENSE_BSD3, and "Vivid Solutions Inc." and "Martin Davis" should
only be in each of the source files.

Eventually, for an overview, a COPYING file could express the
licensing layout of the whole codebase mentioning roughly which
parts are under which license and owned by whom.

Does it sound ?

Hey Sandro -

I am checking against the uDig project - here is an example CswCatalog.java
<https://github.com/locationtech/udig-platform/blob/master/plugins/org.locationtech.udig.catalog.csw/src/org/locationtech/udig/catalog/csw/CswCatalog.java>
that
is similar to the one you provided. My understanding is the file is being
distributed under the EPL and BSD license (and the person who uses the
software gets to choose which one they use).

The uDig project has not graduated from incubation yet so it may not be the
best example (although I did lots of research when changing license). Do
you have another example we could look at?

I think there was a distinct "vivid solutions" BSD license - and although
there are two files only one of them is titled "Vivid Solutions BSD License
v1.0".

Great to talk this through - we so need to recruit you to help mentor
projects in incubation.

Hello,

does this license change apply to the forthcoming JTS releases or does it apply to all released versions of JTS as well?
