Re: [science-iwg] Eclipse Datasets for Science

[UOMo <uomo@xxxxxxxxxxx>]

Tracy/all,

Great to see, thanks for the update.

If you take the effort of trying to help Apache Commons Math 3 into Orbit, what about JScience, and do you use any of the "org.jscience" parts at all or just "javax.measure"?

As of now at least uDig got a LocationTech P2 artifact 

jsr-275-1.0-beta-2.jar

based on a CQ that's already been accepted by Eclipse IP. Reusing that in the "main" Orbit does not seem a problem at all.

While JScience 4.3.1 (http://search.maven.org/#artifactdetails%7Corg.jscience%7Cjscience%7C4.3.1%7Cjar) on MavenCentral claims to use Apache 2.0, every source artifact or the Java.net project https://java.net/projects/jscience always suggested the license was BSD. 

Leaving the last "official" version of JSR-275 aside, which is used by GeoAPI 3.0 (thus if a project like uDig used GeoAPI 3.0 and JSR-275 "beta-2" the two versions are quite different with some classes being simply incompatible!) what I saw from the JAR it looks like Jean-Marie never upgraded JScience 4.3.1 to a later version of the JSR, hence that CQ-approved bundle should work for you if you use JScience 4.3.1 now. 

The license of the standalone JSR did change, but being part of the "bundle" JScience in this form it is safe to assume, BSD works. 

Would you consider using that, or prefer requesting the whole JScience 4.3.1 bundle (you must have created an OSGi enabled variant already) to be added?

Either way also seems a viable path for IoT projects like SmartHome, they tried using JSR-275 (based on this "beta-2" I believe), JSR-363 (which is not approved by IP folks at this point either, similar to Apache Commons Math 3) and Unit-API 0.6.1, also approved and available in Orbit. If you found a dependency common to most Eclipse/LocationTech project that would certainly be beneficial to all projects;-)

Regards,

Werner

Hi all,

I hope you have been having a good time considering Eclipse Datasets
for Science.

I pushed a new branch
(https://github.com/jonahkichwacoders/org.eclipse.dataset/tree/apache_math3)
showing the upgrade to apache commons math3 library (assuming it gets
through ip review and into Orbit sometime soon).

On reviewing the differences (manually + using PDE API analysis) it
seems the only API effect is the
org.apache.commons.math{3}.complex.Complex dependency. Obviously
ComplexFloatDataset and ComplexDoubleDataset have lots of methods that
have Complex in their signature. Additionally, Maths, Stats,
AbstractDataset and a few other places rely on which Complex.

So, once org.apache.commons.math3 is approved, is there anyone who
needs IDataset to work with org.apache.commons.math.complex.Complex?

Jonah,

We do. We require Complex numbers for our Reflectivity Simulator.
