    • Symbols, properties and relations
    • Symbols and things
    • Symbols versus implementation mechanisms

  • Abstraction: visual versus mnemonic
  • Solids and voids in building representations
  • Paradigmatic and syntagmatic dimensions

 

  • Data and information instances
  • Semantic data types: primary, anti-data, derivative, operational, metadata
  • Information instances by scope: single symbol versus multiple symbols

 

  • Structured, semi-structured and unstructured information sources
  • Information flow: what, who, how, when
  • Completeness, coherence and consistency
  • Information authorship versus information custodianship
  • Process diagram: sequence of tasks in a digraph representation
  • Information diagram: information instances and flows
  • I‑P‑O: transition from process to information management
