Intermediary Architecture: interposing middleware object services between Web client and server

This paper describes the Intermediary Architecture, a middleware architecture which interposes distributed object services between Web client and server. The architecture extends current Web architectures with a new kind of plug-in, making a new colleciton of Web applications easier to develop. Example services including Web annotations and Web performance monitoring are described.

Open OODB: a modular object-oriented DBMS

The Open OODB project, part of the DARPA Persistent Object Base (POB) Program, is an effort to build an open, extensible object-oriented database management system (OODB) in which database functionality can be tailored for particular applications within an incrementally improvable framework. The system is designed to serve both as a platform for research and as a testbed that can meet the needs of demanding, next generation database applications. The Open OODB project goals are to describe the design space of OODBs; build an architectural framework that enables configuring independently useful modules to form an OODB; verify the suitability of this open approach by implementing an OODB to these specifications; and identify opportunities for building consensus that can lead to much-needed OODB standards. The motivating factors in this approach were that our previous experience in object-oriented databases had convinced us that different applications have differing requirements, and that a monolithic system is unlikely to meet the needs of many demanding kinds of applications.
