XUES
XUES (XML Universal Event Service) is PSL’s sophisticated event manipulation system. XUES is supported under the DARPA DASADA project, and is part of the KX architecture. XUES consists of two parts:
Event Packager (or EP), which serves as a data aggregator, flight recorder, and event transformer for PSL’s KX system. Features include support for extensible event formats and conversion (currently supports Siena, Elvin, and XML); event recording and playback to/from SQL as well as memory; and support for time synchronization and simple event rewriting.
Event Distiller (or ED), which is a flexible event pattern-recognition/gauge architecture. Features include multiple-event pattern recognitions, including “success” and “failure” situations; timebound validation (e.g., events received in order within specified timebounds); wildcards to support event patterns. ED currently communicates either via Siena or direct method calls.
Further information on XUES is available:
- XUES Flyer (6/01)
- Event Packager 1.9.1 documentation and Javadoc (current as of September, 2002)
- Event Distiller 2.0 documentation and Javadoc (current as of April, 2002)
DISCUS
Decentralized Information Spaces for Composition and Unification of Services
The DISCUS project focuses on forming temporary alliances among existing legacy systems that may span organizational boundaries, to rapidly deal with a unique and temporary problem. This integrated suite of tools, termed a Summit, will help operational teams to achieve quick understanding and resolution of the problem at hand.
A summit is formed by composing services from different Service Spaces, where each service space is an autonomous collection of services allowing selective access to its services. The extent of access allowed by a service space to external entities is based on their credentials and the nature of the problem, thus creating a dynamic trust model. A Treaty, representing a contract, is then formed amongst the service spaces of these participating services.
Each service space enforces normative interaction between the ‘enlisted’ services of a summit by intercepting and verifying every operation with the relevant treaty. Once the services within a summit have accomplished their mission, the summit can be dissolved.
