Schema... Philosophy... Writing definitions... You came to mind
  today at work. So did "Zen and the Art of Motorcycle
  Maintenance.* How does one define "quality" as a measurable
  thing? I chose to use the noun definition as in "a quality",
  characteristic, or attribute. The problem is then categorizing
  it uniquely enough by measurable attributes to "define"
  quality-X. Physical, computational, methodology, actors,
  behaviors... Ugh."[1]Kenneth-Udut-schemaCategorization. So many
  ways to draw conceptual lines but making ones that don't have
  overlapping attributes is far trickier** *The "attributes of
  attributes.... " down the rabbit hole we go...*tongue emoticon
  == I think of maps overlapping maps overlapping maps. You never
  get enough qualities to describe "the thing" perfectly but if
  you overlap enough maps, you can get a decent approximation. I
  think you're going to glow brightly in this. You're the right
  person for it. The fascinating part about schema is that it
  becomes law. It'll just be "part of the system" and few will
  question it, if any. That's the nice part about being the pro.
