Re:Show HN: Npm module that makes easy to convert JSON to CSV by paulddraper on Thursday June 08, 2017 @07:38PM (#14518048)
Protocol buffers don't tell you what the data types are either in the actual message.

It's a trade-off, but I prefer to communicate format out of band, not in every single message.

My take: include a schema when you can and there's a justification and it's practical. IMO even JSON is a (very limited, "name only, no type") type of schema. If it becomes impractical for something you're doing, stop and switch to something less redundant.
