The data in this product is collected for the purposes of valuing properties for the collection of Rates in Northern Ireland and was not originally intended to be a standalone data product.  Consequently, some fields may not be fully populated and OSNI has no requirement to do so for valuing properties. These fields are noted in the dataset as being not required.
