Relicensing of EnArgus Ontology

Hi all,
this is a general question to those who might have insights on the state of the EnArgus ontology. There have been rumors that the EnArgus ontology will actually be relicensed under a free license. Does anyone here maybe know more? Specifics such as, the actual license, point of time for relicensing, links, etc. would be very interesting for the development of the Open Energy Ontology. Any info is much appreciated.

(I though Q&A was the better category, even though technically it might be licensing question, but feel free to redirect me)

Thank you and best wishes, Christian
