    The following list of key concepts from the previous chapters is a reminder or checklist of what can be used in solving information problems, e.g. in the following exercises.

    • Symbolic representation
      • Symbols, properties and relations
      • Symbols and things
      • Symbols versus implementation mechanisms
    • Graphs: objects and relations represented respectively by vertices (nodes) and edges
    • Directed graphs (digraphs): graphs consisting of nodes and arcs (edges with a direction)
    • 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
