The same data is inconsistent across publishers
Often the same specific types of data are defined or formatted differently depending on the publisher. This inconsistency exists even where a standard is in place.
For example, among the 330 lists made available to meet the brownfield register standard we found 31 different file formats and a wide range of character encoding, blank lines, blank column names, incorrect formatting, incompatibility and other useability issues.
This widespread inconsistency across publishers is problematic for anyone developing data-based products that serve the housing market nationwide.
