Introducing Interoperable Objects
[author : Ray Valdés]
You can't tell the players without a program. DDJ's senior technical editor surveys the world of interoperable objects, from object models to compound-document architectures.
OMG's CORBA

Microsoft's Component Object Model (COM) is a component-software architecture that allows applications and systems to be built from components supplied by different software vendors.
IBM's System Object Model
[author : F.R. Campagnoni]
The System Object Model (SOM), the linchpin of IBM's approach to interoperable objects, will eventually underlie all of IBM's object-technology offerings, including OpenDoc, the Taligent frameworks, and the Workplace family of operating systems.
OpenDoc

OpenDoc is an open-architecture-enabling technology designed by Apple for creating compound documents which can contain many different types of data, such as text, graphics, tables, video, sound, and animation.
The Architecture of the Taligent System
[author : Michael Potel and Jack Grimes]
The Taligent system is a web of frameworks that includes an object-oriented application-programming model, a fully object-oriented operating environment, and a suite of framework-based developer tools that complement the programming model.
OLE Integration Technologies
[author : Kraig Brockschmidt]
OLE 2.0, which is built upon Microsoft's COM, is a component-integration technology for interoperable objects that can be located inside applications, in-process DLLs, or out-of-process EXEs.
