So you have bundles as addressable resources: /subsystem=osgi/bundle=0 /subsystem=osgi/bundle=1 /subsystem=osgi/bundle=2 etc... and then you'd like an operation /subsystem=osgi:list-bundles ? Isn't that what you get when you call /subsystem=osgi:read-children-names(child-type=bundle) or simply in the CLI ls bundle ? > |The attributes you mention are fine for a start, however please have > a look at BUNDLE_TYPE > <http://www.osgi.org/javadoc/r4v42/org/osgi/jmx/framework/BundleStateMBean... > and check whether you want to support one or the other as well.

From core 4.3 start level is actually an API on the Framework (you need to adapt bundle 0 to get the start level API) so for the future it might actually be more consistent to represent this as a property of the framework. (BTW the Start Level services will still be supported for BW compatibility). > |For consistency the bundle operations should be called start/stop | > | > ||/subsystem=osgi/bundle=1:start > ||/subsystem=osgi/bundle=1:stop > | The reason why I suggested start-bundle and stop-bundle is that start and stop are highly generic and I was worried that in the future there might be global operations called start and stop.
