SAM (formerly known as StreamLine) uses Storm PMML Bolt Storm integration (https://github.com/apache/storm/tree/d5acec9e3b9473a0e8cf39c7e12393626a3ca426/external/storm-pmml) which uses JPMML evaluator (https://github.com/jpmml/jpmml)
@Eric Brosch With AGPL we are not allowed to package the JPMML dependency along with our ASLv2 Licensed Storm or SAM (Streamline). We build this as a compile time dependency and when users deploy the topology we fetch JPMML artifacts from maven central repo during the deployment. Its users who are in control which version of JPMML artifact they would like to use and there are older versions which are compatible with AGPL license.
Looks like openscoring also offers jpmml under a BSD license for a fee, see below.
Unfortunately, it appears there's a gray area between "we just want to use the software" and "want to redistribute proprietary software based on this code." The wording of the attached blurb from openscoring suggests they think "use" of AGPL code is fine, even though the FSF stance seems to be that GNU AGPL is only compatible w/ GPL: https://www.gnu.org/licenses/why-affero-gpl.en.html
