Static lookupUses the ContentToModelRegistry to look up a strategy to create a model element for the given contentUri.

Static triggerThis method is called when a marker is added to the editor. It receives a markerData object and fetches the data to render the content. It then renders the content in the editor and finally removes the marker.

The DataToModelMechanism is a utility class that handles content insertions into the editor and adjusts the editor's model accordingly. To be precise, it actually receives information about a previously added marker, fetches the required data and displays it at the marker position.
How this works with other ContentClipboard Plugins:
The ContentClipboard plugin integrates into the CKEditor's Input Pipeline and evaluates input events for CoreMedia Content inputs. Whenever an input is received, a placeholder marker gets inserted at the corresponding cursor position.
Markers are used to indicate or highlight different things in the editor's view, and in this case, are used to display a loading animation since the actual contents might take a while to load. The ContentClipboardEditing plugin listens to markers getting added and triggers the DataToModelMechanism if needed.
DataToModelMechanism in Detail:
The DataToModelMechanism is executed whenever a marker is added and receives the corresponding MarkerData object. The MarkerData holds information about the input data, such as the contentUri or the size of the insertion.
Now, the DataToModelMechanism uses a Studio service to resolve the type of the content object from the given contentUri. The type is needed to figure out how to render the content in the editor, or more precise, how the model the content type is defined. This information is provided by the ContentToModelRegistry, which allows other plugins to register model creator strategies for different content types.
Now, the model then is written, the view updates accordingly and the marker (loading animation) gets removed.
