Subject: Portable Execution or Portable Source? [ changed the subject, was Conf call today.. ]
Edwin, I agree with what you recap (what Frank L. stated). This use case is just exposing some of the less clear goals of BPEL. Monica, Yes, it may be related several related issues already open as you pointed out. .Sazi -----Original Message----- From: Monica Martin [mailto:monica.martin@sun.com] Sent: Sunday, August 17, 2003 4:47 PM To: edwink@collaxa.com Cc: Sazi Temel; 'John Evdemon'; wsbpel-uc@lists.oasis-open.org Subject: Re: [wsbpel-uc] Conf Call today at 4 PM ET / 1 PM PT Edwin Khodabakchian wrote: >Sazi, > >I think that Frank L. stated it well in one of his previous emails: the goal >of BPEL over time is to create a congruent view between the design >representation of a process, it executable representation and the >monitoring/reporting representation.
