WebServicesResourceFramework (WSRF), WebServicesNotification (WSN), and WebServicesDistributedManagement (WSDM) are emerging Web services standards that, respectively, define ways to expose and control stateful resources, expose subscription-based notifications, and use Web services as an enterprise management protocol.
Just last week, [http://www.hp.com/ Hewlett Packard] and the [http://www.globus.org Globus Alliance] contributed implementations of WSRF and WSN to [http://www.apache.org/ Apache]. The implementations are hosted as [http://incubator.apache.org/ Incubator] projects sponsored by the [http://ws.apache.org/ Web Services project]. The intent is that they will eventually be ws/ws-fx subprojects. The WSRF implementation is called ["Apollo"], and the WSN implementation is called ["Hermes"].
Additionally, HP contributed an implementation of ManagementUsingWebServices (MuWS), the core specification of WSDM. This project, also hosted in the [http://incubator.apache.org/ Incubator], is called ["Muse"] and is intended to eventually be a ws subproject.
