Hi, So this has been around for some time:
https://github.com/gchq/Gaffer <https://github.com/gchq/Gaffer> At some point I added an Issue to their repo that has since been closed: https://github.com/gchq/Gaffer/issues/11 <https://github.com/gchq/Gaffer/issues/11> You can see how awkward their query interface is: https://github.com/gchq/Gaffer/wiki/Getting-Started <https://github.com/gchq/Gaffer/wiki/Getting-Started> They would be much better served by TinkerPop. Anyone interested in making Gaffer TinkerPop-compliant? Note that they are an Apache2.0 licensed project. Thanks, Marko.
