Hi Feng Xiao, I saw your message which I can't find here for some unknown reason. I was not criticizing google, we all love google and protobuf :) I was not expressing my dissatisfaction which I actually don't have. Sorry for wrongfully giving you that impression. I was just a bit curious and I thought writing them out was fun. And it is truly stupid for me to think openrtb has something to do with google just by the fact it was hosted on google code XD; Actually in the spec of OpenRTB, there's a suggestion that it can be formatted by any of json, avro, protobuf etc. So I think it's no bad to have a try. And as I know protobuf is also what google doubleclick chooses to use.
About the ext field, thanks for your advice. I have defined them by protobuf's extensions. I don't know if it is proper.
