  • sTheory: Specific Theory
  • aModel: Abstract Model
  • cModel: Concrete Model
  • dPractice: Domain Practice
  • gPractice: General Practice

You can find some case studies in The Knowledge Curation Toolkit #1: Theme U for Single-theory Curation.

Though the HERO U diagram is designed for curating existing theories and their applications, it…
