DEFINITIONS

  • Model: �„A model is a description of what the modeler thinks to �be relevant of a system.“
  • Metamodel ...
    • Is a modeling framework consisting of
      • Modeling syntax and semantics (concepts and their meanings)
      • the (graphical) representation of the concepts
      • and (sometimes) additional rules for modeling

3LGM² – META MODEL

  • 3LGM2 = 3 – Layer Graph-Based Meta-Model
  • … used for modeling information systems in healthcare and…
  • … defines concepts needed for modeling the architecture of HIS on 3 layers
  • … specified by UML diagrams

3LGM² – META MODEL

  • 3LGM²-B = basic metamodel
  • 3LGM²-M = for modeling message-based communication
  • 3LGM²-S = for modeling service-oriented communication
    • Used for the FAIR4Health model

3LGM2: DOMAIN LAYER

  • (Enterprise) function – What is done?
    • E.g.:

​

  • Entity type – Which objects/information are used for or interpreted by functions?
    • E.g.:

​

  • Organizational unit – Where are functions executed?
    • E.g.: Data Scientist

3LGM2: DOMAIN LAYER

  • The function „De-identification” …
    • … uses the entity type “FHIR Ressource Type”
    • … updates the entity type “FAIRified data”

3LGM2: LOGICAL TOOL LAYER

  • Application component – supports functions, computer-based or non-�computer-based
    • E.g.:

​

  • Database system – stores entity types
    • E.g.:

​

  • Interface, communication link – communicates entity types
    • Invoking a service: yellow triangle
    • Providing a service: green circle

3LGM2: PHYSICAL TOOL LAYER

  • Physical data-processing systems – Where are application components installed on?
    • E.g.:

​

  • Data transmission connection – Which physical data-processing systems are connected?
  • Virtualization of physical data-processing systems
    • E.g.: Docker images

ADVANTAGES

  • Meta model is a guideline for using the modeling language
    • Each concept is described and explained
  • Shows each role what tasks they must execute and what application components they must use
  • Overview on which application components is deployed on which hardware component
