Given that the only current widely used Jena/Sesame abstraction layer,
the RDF2GO project, are no longer actively maintaining their
libraries, there is room in the market for a Jena/Sesame wrapper API,
if it is kept up to date with recent versions of both libraries.

Given that the underlying OpenRDF API is made up of interfaces, as
opposed to Jena that uses classes for important parts of their API, it
may be viable to switch to using the OpenRDF API with a non-Sesame
implementation for the Repository, and/or Sail APIs and work on a
conversion layer between Jena and Sesame where necessary, possibly
based on the library that Andy Seaborne and I have worked on at GitHub
in the past [1].
