MAGNETAR (Metaprogrammable AGent NETwork ARchitecture) is an open reference architecture for building large-scale collaborative multi-agent systems. The highlights of this architecture include:

• Compliance with High-Level Architecture (HLA) specification propounded by the Department of Defense (DoD)
• Use of meta-programming with XML scripts
• Use of the MORPH paradigm for information modeling
• Use of the blackboard problem-solving model
• Component-based design of modules

Magnetar is an architecture for what we call a Collaborative Metaprogramming Framework (CMF). A CMF is a framework that allows creation of software products by collaboratively instantiating them from a template that defines a family of products. In essence, Magnetar is an architecture that is highly suited to, but not limited to, multi-user simulation systems that require collaboration over networks.
