OPA is developing a flexible, easy-to-use GUI application framework that provides services common to most GUI applications such as those listed below. OPAs ultimate goal is to build an instant print management system ontop of this framework.

The OPA platform is based on a modular structure where developers provide packages that are loaded into the kernel. The modules are supplied as Java ARchive files. The kernel provides basic services common to most GUI application domains such as:

• window management
• locating services
• user option management
• GUI construction on startup

Most application developers do not need to access the Kernel directly via source code manipulation, rather the modules provide information to the kernel as to what services are required (eg. GUI construction). This `black box` approach simplifies development time and reduces the learning curve inherent with application framework use.

The latest project Gantt chart is available here.

OPA relies on the efforts of the Open Source Community. In particular some people have made substantial contributions to the project. You can find out more about this small team here.
