Right now, we are thinking that it will be conceptually a map of field name to value (even if possibly not represented as an object). That would require converting multi-part names to strings, which we typically do using a simple joiner like this. If there are collisions, we would omit the values. -- This is an automated message from the Apache Git Service.
