Aspects and aspect properties
A list of the aspects and aspect properties that the Context Engine can return.
- Aspect property data types
All aspect properties have one of the data types listed in this topic. - Aspect property defaults
All aspect properties have a default value, which serves as a fallback value if the Context Engine cannot determine the actual value (for example, if an aspect property defined in a custom vocabulary fails to be resolved). Use the API to find out default values for built-in aspect properties; in custom vocabularies, a default value is specified in thedefaultattribute of the custom property. - Aspect property hierarchy
Aspect properties of type Boolean (also called a context segment) can be organized in a hierarchy by defining their semantic relationships using therequiresandimpliesattributes of thepropertyelements. - browser aspect
