The IDLink table enhances interoperability establishing relationships between this product and the following products for Great Britain:
- Address Fabric™ Data
- Buildings Great Britain
To accurately reflect linkage between addresses, corresponding parcel boundaries, and any related building characteristics, a number of factors must be considered. The IDLink table is delivered as a relational model to effectively represent these real-world scenarios. Each row contains relationship classes, along with primary and secondary keys. Available relationship classes are:
| Relationship Class | Relationship Description |
| 1 | Address and Parcel Boundary |
| 2 | Address and Building Structure |
| 3 | Address and Building Unit |
| 4 | Building Structure and Parcel |
| 5 | Building Unit and Parcel |
| 6 | Building Unit and Building Structure |
The IDLink table can be used for specific property-related queries, such as generating lists or counts of all parcels linked to a specific address, or identifying building features (Building Unit) associated with an address or building footprint (Building Structure).
Each relationship is based on unique identifiers included in data products from Precisely. The PreciselyID, a unique and persistent identifier for an address, serves as the cornerstone of the IDLink table. Once related feature IDs are identified, they can be used to query polygonal geometries and associated attributes from other licensed Precisely products.
