• CASCaDE is an Object Management Group (OMG) Request for Proposal for submissions to become a standard

• The OMG CASCaDE initiative aims to build a shared ontological foundation for modeling complex, multidisciplinary cyber-physical systems.

• Their goals include:

  • Achieving semantic interoperability across modeling tools and domains

  • Supporting digital engineering throughout the system lifecycle

  • Clarifying the meaning behind system elements and interactions

• CASCaDE spans:

  • Electronics • Fluidics • Mechanics • Software • Human interaction • Systems of systems

• A distinction:

  • Standards like SysMLv2 or OWL offer neutral, formal semantics.

• What’s still missing:

  • Real-world semantics—the actual entities, roles, functions, and processes that models are about.

• That’s where IOF ontologies come in.
