Looks good. Pending updates on roundtrip_test.go and _http.log

Looks good. Pending updates on roundtrip_test.go and _http.log

Done, I also removed the empty URI struct, and added CreateTime. UpdateTime remains semi-commented out because I don't think we even output it. But I guess I can add it to the schema?
