I posted a preliminary version of the benchmark code here:

https://svn.apache.org/repos/asf/sis/release-test/maven/src/main/java/org/apache/sis/test/referencing/CoordinateOperationComparator.java

I will try to help for Proj4J wrappers (so it can easily be added to the
tests) later this month, after OGC meeting.

GeoAPI for Proj4J?

Posted by Martin Desruisseaux <ma...@geomatys.com>.

Hello Rob

Do you have a code repository setup for Proj4J? If yes and if it is okay
for you, I may be able to explore this weekend the possibility to expose
Proj4J referencing services through GeoAPI 3.0.1 interfaces.

    Regards,

        Martin

Thanks for the code Martin.

Let me know when you are interested in starting that up, I'll give an
update on Proj4j's progress - we might have gotten it into LocationTech's
repo by then.

Best,
Rob
