Protobuf schemas that use import

[einarjohnson]

Hi,
I am working on a project that is using Protobuf to define schemas for events that are published to Kafka. We use import statements in most messages to re-use definitions. The folder structure is roughly like this

proto\v1\common
proto\v1\message-domain1\msgtype1.proto, msgtype2.proto, ... + files that are imported by msgtypeN
proto\v1\message-domain2\msgtype1.proto, msgtype2.proto, ... + files that are imported by msgtypeN
...

where message types are importing either from the common folder or from proto files within the same directory.

What are the best practices in importing projects like this into the apicurio registry? I am mainly thinking how I can get the imports to work and be recognized by the schema registry. Do I need to flatten out the each messagetype into a single proto file before importing? If so, are there any tools to do this?
