Hi Duplex, no worries about the language, none of us are native speakers, so we perhaps won't even notice ;)
Regarding BPEL: It is a graphical language for orchestrating web services. The goal is to establish a two-level-programming model: On the lower level there will be services implemented in traditional programming languages, made available via WSDL/SOAP interfaces. On the higher level, those services are stitched together so that they create a higher service, ideally providing some business value (like a confirmed travel booking). BPEL also provides all needed means for long running processes like message correlation (i.e. a message sent to a process will be routed to the correct running instance based on the order number or the like) and compensation (i.e. the ability to undo work at a later stage, normal ACID transaction are usually not applicable for long-running processes). You could have a look at http://eclipse.org/bpel/ to see some examples of the graphical representation. Please note that the graphical representation is not standardized, but the visualization is typically similar. One of the task of the project is also to come up with a decent graphical representation for the monitoring. This should be also subject of discussion on this list, since there are a couple of options: a) we could come up with a completely new visual appearance, b) we could try to emulate the visualization of the Eclipse BPEL Designer, c) we could try to define BPEL visualization based on the BPMN 2.0 stencils. In any case, we need some auto layout for the visual appearance. These BPEL models are then deployed to ODE and ODE is able to execute them, i.e. it will follow the defined control flow and will invoke web services, manipulate data or will wait for incoming messages. During the execution it will write a so called audit trail. This is actually an event stream, telling which activities have been enabled/started/completed at what time and what they did. The goal of the monitoring console is to map these events to the graphical representation in order to give users the possibility to see which activity has been completed already and which didn't. With this information they can drill down and tell where the processing is currently in a particular process instance. That's BPEL, ODE and this task in a nutshell. For more on BPEL you could look for the "BPEL Primer" [1]. Please ask any questions that may arise from this.
