Business Process Modeling Notation - BPMI.org, The Business Process Management Initiative have already done BPML there appears to be a BPQL around, now there's a graphical, flowchart-like notation to go with it.

"While ebXML provides a standard way to describe the Public Interface of e-Business processes, BPMI.org provides a standard way to describe their Private Implementation."
note that these are "...business processes that span multiple applications and business partners, behind the firewall and over the Internet."
