Property Graph is built to enable improved interoperability when using two or more Precisely Addressing or Points of Interest (POI) products in conjunction with each other. Initial releases will focus on establishing relationships between the following products from Precisely:
- Master Location Data (MLD)
- Address Fabric™ Data
- Parcel Boundaries
- Buildings
- Property Attributes
- World Points of Interest (POI) Premium
Over time, Precisely will look to include additional relationships between these products through multi-tier spatial analysis, to address specific industry challenges faced by our customers.
Many factors must be considered in order to accurately present the linkage between an address or point of interest, its related parcel (property) boundaries, and any associated property characteristics or buildings. While the typical residential relationship is one address to one parcel, to one building, to one property tax record, the associations between these features are more complicated in the real world. For example, more than one address can be associated with:
- A parcel boundary on a corner lot with road frontage on two different streets
- A building containing apartments, suites, or condominiums
- A building that splits across multiple parcel boundaries
- A parcel boundary with one or multiple buildings containing apartments, suites, or condominiums
- A single address with more than one property record.
To be able to accurately represent such real-world scenarios, Property Graph is delivered as a relational model, where each table contains a relationship class, primary and secondary keys, and a relationship type. The possible relationship classes are:
- Address and Parcel Boundary
- Address and Building Footprint
- Building Footprint and Parcel Boundary
- Address and Property Attribute
- Address and Point of Interest
- Address Parent and Address Child
- Parcel Boundary and Property Attribute
- Parcel Boundary and Point of Interest
- Building Footprint and Property Attribute
- Building Footprint and Point of Interest
Property Graph is built to be extensible and include other relationships within the Precisely Enrich Data Portfolio.
Clients can use these lookup tables within their production platforms to answer specific questions about a property, such as providing a listing or count of all parcels associated with an address, or identifying building features associated with an address.
Linkages will be based on unique identifiers included in each Precisely data product. The PreciselyID, a unique and persistent ID for an address, is foundational to Property Graph. Once feature IDs for a related product are identified, they can be used to query the polygonal geometry and associated attribution in separately licensed Precisely Data products.
