Something I have been wondering. Are UFIs (Unique Feature Identifiers) universal. So, what I mean is are they standard across all datasets? For example if London is 900400 in one set, will it also be the same number in all others?
If by "other datasets" you mean "other datasets from the same supplier" then yes, it might be the same number, if that supplier knows what he/she's doing (I tend to be very skeptical about data standards and quality)
But if I want to make a dataset with a column that signifies a UFI and I assign number "1" to London, there's nobody stopping me.
