This month, have started a project to implement OVSDB protocol, which is specified in RFC 7047. As its first outcome, we have released the project at GitHub and waiting others' responses. 

Currently it only supports list_dbs and get_schema method. Thus, we are anticipating many others' help to make it as a complete OVSDB protocol stack. If you want to join, please refer following URL.
