Introducing the Geomajas Open Source framework for building spatial web applications by Joachim Van der Auwera
Geomajas is a highly secure and very performant framework for building spatial applications which are accessed through the web browser. It does not require browser plugins, making it very suitable for large enterprises and government. The framework has a tight integration between the application back-end and front-end allow high performance and strong security. It can integrate with many data sources. Development is in one language (Java). This makes it easier to build your team as one technology is sufficient and gives you a large pool of potential developers (Java). The framework is modular. There are more than 20 plug-ins offering various enhancements to the core. There are also some additional libraries which can easily be reused in other environments. The presentation will introduce all aspects of the framework.
