Abstract: Techniques are described herein for using operational transforms to perform operations on parallel copies of a document model. A method includes: determining that a first operation is to be performed on a second parallel copy; and in response: determining that a revision of a first parallel copy matches a revision of the second parallel copy; and in response: performing the first operation on the second parallel copy to obtain a calculation result including a first list of commands; applying the first list of commands to the second parallel copy; performing an operational transform on at least one command in the first list of commands based on queued user edits to the first parallel copy, the queued user edits including a second list of commands, to obtain a transformed list of commands; and applying the transformed list of commands to the first parallel copy.

Abstract: A system and method including monitoring an available storage capacity of a data store onboard a vehicle and annotated data stored therein, the annotated data stored in the data store including event data associated with an operation of the vehicle; automatically deleting, in response to an indication of at least one of the available storage capacity of the data store and the annotated data stored therein, at least a portion of the data from the data store; and generating an output including an indication of a completion of the automatic deleting of the at least a portion of the data.
