| definition | Unique signature of the semantic content of a digital object. It is not simply a checksum of a binary data file. Instead, the UNF algorithm approximates and normalises the data stored within. A cryptographic hash of that normalised (or canonicalised) representation is then computed. The signature is thus independent of the storage format. | ||||||

| example | The same data object stored in, say, SPSS and Stata, will have the same UNF. | ||||||
