Domain Services

Commonly-used domain services to use within your app, implemented in Isis core. Some implement API defined in the applib; see summary.

Wicket Viewer About

Features, configuration and UI customisation.

Add-on Modules/Services

Optional supporting modules to use within your app, with implementations in Isis addons (not ASF). Some modules implement interfaces defined in Isis applib (eg auditing), others are standalone (eg excel and tags).

In addition, a full list of all applib services (including those that are implemented by the framework itself, eg DomainObjectContainer and MementoService) is summarized here.

Note that Isis addons, while maintained by Isis committers, are not part of the ASF.
