| Relationship Class Value | Relationship Class Description | Valid Possible Relationship Type Values |
| 1 | Address and Parcel Boundary | 1 - Relationship determined via geocoding 4 - Spatial relationship – primary key entirely within secondary key 32 - Relationship determined via geocoding genealogy Possible combined values: 5 - Relationship determined via geocoding (1) and spatial relationship (4) 33 - Relationship determined via geocoding (1) and geocoding genealogy (32) 36 - Spatial relationship (4) and geocoding genealogy (32) 37 - Relationship determined via geocoding (1), spatial relationship (4) , and geocoding genealogy (32) |
| 2 | Address and Building Footprint | 2 - Relationship determined via multi-tiered spatial analysis 4 - Spatial relationship – primary key entirely within secondary key 32 - Relationship determined via geocoding genealogy Possible combined values: 6 - Relationship determined via multi-tiered spatial analysis (2) and spatial relationship (4) 34 - Relationship determined via multi-tiered spatial analysis (2) and geocoding genealogy (32) 36 - Spatial relationship (4) and geocoding genealogy (32) 38 - Relationship determined via multi-tiered spatial analysis (2), spatial relationship (4), and geocoding genealogy (32) |
| 3 | Building Footprint and Parcel Boundary | 2 - Relationship determined via multi-tiered spatial analysis 4 - Spatial relationship – primary key entirely with secondary key 8 - Spatial relationship – primary key partially within secondary key Possible combined values: 10 - Relationship determined via multi-tiered spatial analysis (2) and partial spatial relationship (8) 12 - Relationship determined via spatial relationship (4) and partial spatial relationship (8) 14 - Relationship determined via multi-tiered spatial analysis (2), spatial relationship (4), and partial spatial relationship (8) |
| 4 | Address and Property Attribute | 1 - Relationship determined via geocoding |
| 5 | Address and Point of Interest | 1 - Relationship determined via geocoding |
| 6 | Address Parent and Address Child | 32 - Relationship determined via geocoding genealogy |
| 7 | Parcel Boundary and Property Attribute | 128 - Relationship based on mutual attribute dependencies |
| 8 | Parcel Boundary and Point of Interest | 1 - Relationship determined via geocoding 64 - Spatial relationship – secondary key entirely within primary key Possible combined values: 65 - Relationship determined via geocoding (1) and spatial relationship (64) |
| 9 | Building Footprint and Property Attribute | 1 - Relationship determined via geocoding 64 - Spatial relationship – secondary key entirely within primary key Possible combined values: 65 - Relationship determined via geocoding (1) and spatial relationship (64) |
| 10 | Building Footprint and Point of Interest | 1 - Relationship determined via geocoding 64 - Spatial relationship – secondary key entirely within primary key Possible combined values: 65 - Relationship determined via geocoding (1) and spatial relationship (64) |
Note: Values are mathematically added, not appended. Thus, a relationship with a Relationship Class value of 1 (Address and Parcel) that also has an address point contained within the parcel would have a Relationship Type of value 5 (1 + 4).
