RemotiveBroker meta database json format schema

Type: object

This JSON schema is used for meta databases which works as an extension to conventional databases.
Works for .ldf and .dbc. The meta database is used by the RemotiveBroker to describe functions not available in conventional databases. Such as, E2E and Covesa VCC naming.
The RemotiveBroker will read a meta database IF the meta database has the same file name as the conventional AND the suffix .meta.json. For example the DBC database ./my_db.dbc and the meta database ./my_db.meta.json will work together.
This document is written for format version 0.1.0
