A property value can be referenced by a property path. The property path points to another property by name. The property may be in the same or a different document. The property value's type must be a reference to another document for each of the properties in the path except for the last.

Sample property paths are:

• Type→Sort Key
• IT Service→IT System→Type

Materializing puts the property value at the end of the path as the value of a property in the referencing document (i.e. the document containing the property path).
