P1. Michael's Thing Principles - Dec. 30, 2018: A Subject is an Actor or a Thing. Actors (Persons, Organizations, and Software Agents) participate in Processes. A Process acts on/accesses Things (e.g. a Pet (with a chip), Car, House, Business Document, Product, Assembly, Part) to perform work. Business Documents and Products are different from the traditional Sovrin concept of a Thing (e.g. Pet (w/chip), Car, House). ()
