Join Active Endpoints CTO Michael Rowley on Tuesday, November 23, for his weekly technical talk CTO Tuesdays at 12pm EST / 9am PST / 17:00 UTC. Register at http://www.activevos.com/ctot. This week's topic is "Expression languages for business processes."

In this episode of CTO Tuesdays, Michael Rowley will be talking about expression languages for business processes. A business process works with data through expression languages. When a decision gateway has to determine which path to take, the high-level question might be something like “is the loan requested a large loan?”, but the implementation will be some expression written against the variables of the process. Both BPMN and BPEL allow the process designer to choose the expression language to use. This talk will look at some of the most common choices: XQuery, XPath and JavaScript – and talk about the advantages and disadvantages of each.

Technologies discussed on CTO Tuesdays cover a wide variety of BPM technologies, including BPMN 2.0, SOA, web services, process modeling tools, BPEL, execution engines, AJAX-based forms development and human task integration.
