The whole architecture is divided into 3 areas:
Apache Netbeans Platform RCP is a generic desktop application developed by Netbeans Development Teams. This platform provides comprehensive support for building rich client applications such as menus, document management, settings and so forth. Instead of writing the same code over and over again, write modules to implement what you need, bundle them up with the NetBeans Platform, and you have a beautiful, branded, cross-platform application. NetBeans based applications are write-once, run-anywhere. You get prebuilt components for free and you solve common problems by reusing, mixing and matching them. Use the platform and the modules you develop as the basis for multiple applications that share common logic. The NetBeans Platform is a solid foundation and set of standards for clear design.

Apache Batik is a Java technology based toolkit for applications or applets that want to use images in the Scalable Vector Graphics (SVG) format for various purposes, such as viewing, generation or manipulation. The project's ambition is to give developers a set of core modules which can be used together or individually to support specific SVG solutions. Examples of modules are the SVG Parser, the SVG Generator and the SVG DOM. More info...
Sketsa is build on top of Apache Netbeans Platform. It acts as Netbeans Module (Plugins) that extends Apache Netbeans Platform. Sketsa itself is divided into several modules:
