Annotation

Annotation

An annotation object, illustrated at right, represents incidental information that can be attached to an object for the purpose of annotating or footnoting that object. You can associate annotations with custom objects, documents, and folders. Annotations:

• Are independently securable. Default security is provided by the class and by the annotated object. An annotation can optionally have a security policy assigned to it.
• Can have subclasses.
• Can have zero or more associated content elements, and the content need not have the same format as its annotated object.
• Are uniquely associated with a single document version, and thus are not versioned when a document version is updated.
• Can be modified and deleted independently of the annotated object.
• Can be searched for and retrieved with an ad hoc query.
• Can subscribe to server-side events that fire when an action (such as creating an annotation) occurs.
• Can participate in a link relationship.
• Can be audited.
