The OS Open TOID data carries five attributes which are all mandatory for each release. These can be used to identify and link affiliated information for a real-world object as well as plotting its real-world position. The TOID represents a range of feature types which related to an even wider range of real-world object types, examples range from buildings (including those without an address), roads, junctions, bridges, trees, fields and more.
