“An enterprise-level data model for a manufacturing customer will span multiple data silos: PLM, ERP, MES, CMMS, QMS, LIMS, Service, Dealership, Warranty, Spare parts, and hundreds of other systems. There is no single system that owns all the data needed to understand a product holistically.” - Pugal Jankiraman

I think this will hold true across manufacturing-level context graphs, in a parent-child hierarchy, where the children are agents that replicate personas and capture their context.
