IBM® Content Navigator uses a model-view-controller (MVC) architecture.
You can use the modeling classes to customize the communication and data exchange between the web client and the repositories.
You can customize IBM Content Navigator at each level of the architecture by using custom plug-ins. You can create plug-ins to implement custom widgets, services, and other components. By creating custom plug-ins, you can integrate information and content from external sources and augment or modify the behavior of IBM Content Navigator.
IBM Content Navigator uses plug-ins to implement various features. For example, IBM Watson Content Analytics is integrated as a plug-in to IBM Content Navigator. The external data service plug-in augments the behavior of many IBM Content Navigator widgets to support the integration of data from sources other than the content repositories. You can use this feature to add such features as choice lists, choice list dependencies, and validation to the web client.
