Properties
Prims can have Properties, which are essentially named and typed data.
A Property within USD is actually a collective term for two distinct types of Properties:
Relationships are Properties that point to other properties or Prims
In the above, you can see that properties are made up from a name and a typed value
These property names can also be namespaced. A property name can have 1 or more namespace identifiers separated by :.
Looking closer at the relationship example, the property name material:binding is actually namespaced. The property’s name itself is binding and it is part of a material namespace.
Namespaces can be used to categorize or group properties together.
