Description
Currently we use and expose a combination of Sesame 2 and Jena 3:

Some of those are exposed in the API - e.g. in
https://taverna.incubator.apache.org/javadoc/taverna-language/org/apache/taverna/scufl2/annotation/AnnotationTools.html
Commons RDF is evolving as a light-weight API with bindings for both RDF4J (newer Sesame) and Jena - but with interfaces that don't expose those.
So it would be a good idea if we could move towards using Commons RDF and from our API only expose RDF interfaces from Commons RDF API – then we are free to swap/update implementations.
Some of this uses with JSONLD in RO Bundle can use the JSONLD-Java binding for Commons RDF directly, and therefore reduce the number of dependencies of taverna-robundle.
Full disclosure: I'm one of the committers of Commons RDF 
Version 0.3.0 adds the RDF4J/Jena implementations, currently under vote.
