Subject: Re: [ubl-dev] UUID
I suppose "universally" has to exclude e-commerce to Pluto from now on... Anyway, the UUID follows a specific algorithm to ensure that IDs generated by this same algorithm are all unique anywhere in the world and across time, with only extremely small and insignificant chances of collision (2 or more generated IDs are the same). So values stuffed into this field need to follow that algorithm in order to achieve uniqueness universally (within Earth). In the original poster's question, he's right to say different transmissions of the same business instance would use different UUID and same business ID. That's theoretically though. There may be practical difficulties in trying to replace different values of UUID into the instance prior to transmission, and retain the overall integrity of the digitally-signed instance if digital signature is used. Need to look a bit more into this aspect I think.
