Network EducationWare (NEW) is an integrated collection of open-source software for synchronous Internet communication, where a class is simultaneously taught to local students and distributed over the Internet. In order to scale use of NEW to multiple courses, we have developed a Web portal that provides coordinated access to each major function. We describe the way this portal works with the NEW client and server software to reduce effort and enhance effectiveness of online course management. The resulting system provides a simple, low-cost means of tending teaching and learning over the Internet. The portal webpages and other NEW software are available at no cost for any academic activity.

The Experimentation Command and Control Interface (XC2I) project has developed an architecture for a Webservice based viewer/controller for use with distributed simulations supporting military experiments. As part of this activity, a capability for Interest Management with three functions is being created. The functions are RoleBased Access Control (RBAC), Area of Interest Management (AOIM), and Aggregation Interest Management (AGIM). While the approach is compatible with High Level Architecture (HLA) for Modeling and Simulation, primary information exchange takes place using the Web services, i.e. software-to-software messaging interfaces that operate over Web protocols such as XML/SOAP. This paper presents a Web Services Internet Management (WSIM) architecture designed to achieve these capabilities in a way that is compatible with simulations using the HLA. The protocols and information flow structure are described, along with the architecture's design rationale, interest management rules, and plans for its implementation. The paper concludes with a description of potential for future development of WSIM, including adoption of the Command and Control Information Exchange Data Model (C2IEDM) and use of Overlay Multicast for data distribution.
