This part of BS 7666 specifies the logical data structure for a gazetteer of land and property, consistent with Part 0 of this standard. It is based upon the concept of a basic land and property unit (BLPU), and specifies the data to be recorded and maintained in a gazetteer. It also specifies the way in which the boundary of a BLPU may be represented and linked to the gazetteer. It does not provide a database design or a transfer format.
This part of BS 7666 is intended for use by those compiling land and property gazetteers, for a range of purposes including property records and addressing. It enables different users of land and property information to link different land and property identifiers (LPI) via a common unique property reference number (UPRN).
