arxiv.org/pdf/1305.1907v2.pdf is not to your liking? –  Carlo Beenakker Nov 17 '13 at 21:38
Thanks, Carlo I was unaware of that paper. I don't subscribe to hep-th; wish cross-referencing were more common. Have also discovered Vaisman's 1203.0836 –  Jim Stasheff Nov 18 '13 at 13:17
Now there is arxiv.org/abs/1406.3601 –  Jim Stasheff Jul 9 '14 at 21:19
