This page details upcoming data that will be provided for the Data Entity Catalogue Code List in the OS NGD from the end of September 2025 to give you early insight. Data schema version 2.0 for this code list is currently not available through the live access services. The information on this page is as accurate as possible, but is subject to change before launch.
This code list is used in association with the Cross Reference Feature attribute which is present within the Related Entity Related Component. The code list describes the key identifiers referenced by the attribute and their source datasets.
V2.0 of the code list was released on 25 September 2025.
