Wine is a way to run Windows software on Linux, but with no Windows required. Wine is an open-source Windows compatibility layer that can run Windows programs directly on any Linux desktop. Essentially, Wine is trying to re-implement enough of Windows from scratch so that it can run all those Windows applications without actually needing Windows.



TRAK Metamodel


The definition of the metamodel for TRAK (defines allowed AD elements and relationships i.e. tuples/ triples for the TRAK viewpoints and views). TRAK is a general systems-thinkers'/system engineering enterprise architecture framework. It is simple, user-friendly, pragmatic and not limited to IT. Forms basis for RDF + OWL ontology description - see https://trakmetamodel.sourceforge.io/vocab/TRAK_metamodel.html


  • defines tuples / triples (declarative statements) that appear in TRAK viewpoints and views
  • designed by systems engineers for others & based on need / typical application
  • supports simple, pragmatic, no nonsense, just "good enough" way of addressing typical concerns (not populating a data model)
  • metamodel (A3) for easy reference when modelling - see snapshot below for example
  • defines each TRAK node and relationship type in architecture description)
  • defines attributes/properties of each element type e.g. dublin core, security descriptors, safety-related
  • provides tests for/against to determine what type to use when modelling using TRAK
  • defines colours/ presentation for each element
  • defines each relationship (between node)
  • defines tuple set rules (combinations of nodes with relationships)
  • provides rationale/justification for relationships
  • released under GNU Free Documentation License
  • written for users/architects/human beings - not specifiers or tool vendors
