A system and method for managing resources in a programming environment includes providing mutable entities including related data including triples, listening for changes in the related data, and triggering a first construct in accordance with the changes in the related data to update the mutable entities. Updates are propagated from the first construct to other constructs such that a cascade of updates occurs. The cascade of updates is executed concurrently such that the updates are propagated to completion and are executed all at once relative to other cascades of executing constructs.
