Hello,

> any progress with ogm-orientdb?

At the moment we are not actively working on the OrientDB integration, this is not for lack of interest but for lack of resources.
I know that there are some contributors that are experimenting with it but it is still in a early prototyping phase (https://github.com/schernolyas/hibernate-ogm/tree/orientdb/orientdb).

> Do you need help with it ?

Yes, as Sanne Grinovero pointed out, our team is small and there are many features that we want to add/fix in OGM core and several improvements we would like to make on the existing datastores. If you are willing to contribute to the project and work on the OrientDB support we are willing to help (this is already happened with CouchDB and Redis, for example).
