11.11. Annotations

Rather than creating a separate "Annotation" object like what exist in the XMI models, the annotation's description and keywords are simply recorded as a "mmcore:description" and "mmcore:keywords" properties on the node created for the target of the annotation. This is really nice, because if a description is placed on a relational column object in a model, then that description appears as a property directly on the corresponding "relational:column" node. Note that when any annotation properties are placed on a node, the "mmcore:annotated" mixin is added to that node.
