Modular Framework

IDM implements infrastructure modules that run in an OSGi framework. It exposes core services through RESTful APIs to client applications.

The following figure provides an overview of the architecture. Specific components are described in more detail in subsequent sections of this chapter.

IDM architecture

The IDM framework is based on OSGi:


OSGi is a module system and service platform for the Java programming language that implements a complete and dynamic component model. For more information, see What is OSGi? IDM runs in Apache Felix, an implementation of the OSGi Framework and Service Platform.


The Servlet layer provides RESTful HTTP access to the managed objects and services. IDM embeds the Jetty Servlet Container, which can be configured for either HTTP or HTTPS access.
