Part of this will be determining which versions/variants should be supported: https://en.wikipedia.org/wiki/Universally_unique_identifier#RFC_4122_Variant Version 4 (random) UUIDs is an obvious choice, but should any others be supported initially? Perhaps the implementation could be a simple function named random_uuid() which either takes no parameters or a single parameter "$version" which defaults to 4? Regards, Colin
