System Object Model (SOM) is an object-oriented shared library system. DSOM, a distributed version based on CORBA, allowed objects on different computers to communicate. System Object Model (SOM, SOMObjects) is a language neutral object model.

  • Replacement
    • somFree is a Portable implementation of SOM, but it hasn't been ported to OS/2. Open source under the LGPL v3.
    • NOM (Netlabs Object Model) was an implementation of SOM that was going to be part of Voyager, but it never got finished.
