Questions tagged [uti]

A 'Uniform Type Identifier' (UTI) is a string value used to identify abstract and specific types of item. It uses a reverse-DNS syntax, and is used extensively by Apple for determining types of data files. UTIs exist in an inheritance-based structure, allowing data types to be organised hierarchically. Apple maintains a list of public UTIs, and allows the creation of private, or 'third-party' UTIs.
