A New Application Framework Design

...

• Configuration.
• Globalization (locale, time zone, currency).
• Logging.
• Security (authentication/authorization).
• Actor Management (profiles, roles - required for security; Actors - people, external services) Think of UML Actor.
• Persistence (file system or database).
• Required to remove dependency on Party
• Data Store (entity engine).
• Lang package to provide classes that are fundamental to the framework
• Services.
• Runtime management.

Design Goals

• Single jar file.

• Compact, small memory footprint.
• Scalable from SBCs to enterprise-class ERP systems.
• Reuses existing technologies.

• Easy to configure and maintain.
