Each event frame has a name, start time, end time, one or more attributes, and one or more referenced AF elements. An event frame shares some similarities with an element but contains additional metadata. You can perform many event frame actions with specific element-related controllers.
-
Event Frame Template As with element templates, you create event frame templates to standardize and manage the attributes for different types of events, rather than a specific asset. Because event frame templates are a special type of element template, you can perform many of the same actions:
- To create an event frame template, CreateElementTemplate in the asset database and specify the InstanceType to be "EventFrame".
- To view the list of event frame templates in an asset database, GetElementTemplates in the asset database. This action retrieves both element and event frame templates.
- To view, update, or delete individual event frame templates, you can use any available actions in element template.
-
Event Frame Category An event frame category is equivalent to an element category.
-
Event Frame Attribute and Attribute Template You access attributes that are defined in event frames in attribute, whereas you access attribute templates defined in event frame templates in attribute template.
