IGRP Framework is a powerful and highly customizable platform developed by the Operational Nucleus for the Information Society (NOSi) to create web applications, it provides out of box, several modules to make easy to create stand-alone, production-grade web applications: authentication and access-control, business processes automation, reporting, page builder with automatic code generation and incorporation of the Once-Only-Principle, written in Java. IGRP Framework WAR - Contains some keys resources that give UI to IGRP Framework and others supports files.
