Interlanguage object sharing with SOM

Abstract

Object-oriented programming languages may encourage reuse at the source code level, but they inhibit reuse at the binary object level. Differences in object representation make it much more difficult to share objects, even across different implementations of the C++ language, than to share libraries between different procedural languages such as C and Fortran. IBM has addressed this problem through the System Object Model (SOM). The purpose of this paper is to provide a brief description of the SOM and the mapping from SOM to the object models of several languages: C++, Smalltalk, OO COBOL, and to discuss how binary object interoperability can be achieved through SOM.
