Hi Kent Bair
Luca Garrily promises that OrientDB V3 will be GA in October 2017. In this way, I have to prepare new PR for Davide D'Alto (migration to https://hibernate.atlassian.net/browse/OGM-650 ). And after it, Davide D'Alto will have ability to create repository.

About " Do you have a list of outstanding issues you need help fixing/testing?" . I prepared first version. The version supports document-oriented functionality only. You can take part in development process for the dialect, if you want.
