BACM12 — Reconsider the packaging and namespace conventions

The justification for namespaces is to permit parts of the model to be used independently. The current packaging is close, but crossmaps between value stream and capability are defined in Capability and crossmaps between ValueItem and Outcome are defined in Customer. Customer mixes together Journeys and Value Streams. Consider repackaging to eliminate crossmaps from the core packages and add new packages with just the crossmaps. This would also benefit use of the OWL as a group of ontologies instead of one large one.
