Hi everyone
I am using apache-sis and I was wondering that some external packaged were
used from org.opengis packages I know from GeoTools (LGPL license).
I asked the apache-sis mailing list and got following response:
Yes the main authors of GeoTools referencing module are now
working on Apache SIS. That is why some classes are similar. A
review of intellectual property has been done in order to port to
SIS only the GeoTools codes that have been written by developers
who have signed the Apache Individual Contributor License
Agreement (ICLA), which is the vast majority of metadata and
referencing code. Each of those classes are listed in the link
below, with a list of commits for each class and actions taken for
the few cases where a commit was not done by an author who signed
ICLA:
https://svn.apache.org/repos/asf/sis/ip-review/
So I can use all provides classes from following dependency even if they have
org.opengis as source? What does the ip-review mean?
<dependency>
<groupId>org.apache.sis.core</groupId>
<artifactId>sis-referencing</artifactId>
<version>${sis.version}</version>
</dependency>
Furthermore following additional information was added.
GeoAPI 3.0.1 interfaces in the org.opengis packages are under OGC
Software License Version 1.0 which is BSD like:
https://www.ogc.org/ogc/software/1.0
A discussion about this license can be viewed there:
https://github.com/spdx/license-list-XML/issues/845
As discussed in above link, a future version of GeoAPI interfaces
may need to move to a slightly different license, the OGC document
license. No decision has been taken yet and the Apache foundation
will be consulted first. In the context of GeoAPI, the OGC
document license is the same than the current BSD like "OGC
software license" with one additional constraint: if a user wants
to modify an interface in the "org.opengis" package, then (s)he
needs to rename "org.opengis" into something else. After (s)he has
done this renaming, the interfaces fall into the BSD-like license.
Note that this is similar to a similar constraints in Apache
license, which said that if we modify an Apache software then we
can not call it Apache anymore; we have to give it a new name. The
"OGC document license" is simply more specific about the
requirement to change the namespace (in the case of Java: package
and module names) in order to avoid conflicts with other
implementations of the standard.
https://www.ogc.org/ogc/document
But this is for future. Current GeoAPI 3.0.1 is BSD-like, and I
plan to have a discussion between OGC and Apache before to
eventually move GeoAPI 3.1/4.0 to "OGC document license" for
making sure that it is okay for Apache.
What could this mean for us?
