The A1√ Architecture Model

The A1√ (the “√” is silent in speech) model provides the basis for development of distributed applications and distributed infrastructure within the CRC for Distributed Systems Technology. The model has been developed to overcome some of the deficiencies in the RM-ODP standard, in particular, to address the diverse requirements of participants in the CRC. This paper introduces the major concepts of the A1√ model, and discusses both its relationship with RM-ODP and how it overcomes deficiencies identified in RM-ODP.
