New WfXML-R Prototype Effort at the Stevens Institute

Posted by Patrice Cappelaere Sun, 30 Mar 2008 13:31:00 GMT

As part of his Bachelor Thesis “The application of Wf-XML to scientific workflow: a satellite imaging case study” Philipp Hansen is currently working with us on a proof of concept prototype for WfXML-R at the Stevens Institute of Technology. His advisor there is Michael zur Muehlen.

He is following a two step approach. First step is the implementation of a WfXML-R interface for Sungard’s Carnot Workflow Engine, which already features the ASAP-based Wf-XML for workflow interoperability. This implementation will be tested with scientific workflows within NASA sensor web environment.

The second step is publishing and discovery of available workflows via APP according to the current WfXML-R version.

This will be the fourth implementation of WfXML-R for RESTFul Workflow Engines.

St Louis, Mar 28, 2008

Just completed a full week of OGC meetings in St Louis. This is the conclusion of OWS-5 (OGC Web Services Interoperability Demo #5) with more than 30 participants.

The NASA SensorWeb is deeply involved in Earth Observation, Natural Resources & Environment. We presented our current ROA-based architecture used to support many pilots and operational demonstrations.
