Abstract: A flexible modeling architecture is described that allows multiple versions of entities of different types to be modeled in a structured fashion with different model sets, with a variety of functional models, each representing a different aspect of the system and allowing generation of any number of artifacts at build-time as well as run-time to result in rapid creation of consistent computer applications to manage concurrently a plurality of entities, dynamically adjusting to the version of metadata on each entity.

Abstract: A system provides representations of connections or other relationships among entities that make up a communications network. The representations may each have a color or shading to represent different conditions of the relationship. The representations may be graphical and may also include textual information as well as graphical hot-spots selectable by a user to provide even more detailed information regarding the relationship. The condition of each relationship may be determined based upon a combination of the conditions of the interface elements which are coupled together to form the communications relationship.
