BPEL Import A slide from a recent Microsoft presentation: BPEL Import 1 BPEL is an interchange format 2 BPEL is like WSDL but for behaviour of services 3 Defines External/Public behaviour across Platform 4 Export BPEL from one platform; import into the next 5 Each platform will have its own execution engine; leveraging the platform strengths I can work with 1 - share business process best practices is something that naturally falls out of that conclusion.  I can work with 2 as an analogy.   I like 4 - kind of the same as 1 though ideally with a fleshed out BPEL standard, "copy" might be better - this may simply be a reflection of MSoft's current implementation.  And 5 is the industry opportunity BPEL brings to the table. It's 3 I have to wonder about - BPEL by its very name is *executable* and generally seems best suited for private processes.  Abstract BPEL gives a view of a BPEL process's external, public behaviour but I am not sure it is enough to really capture all the semantics of a peer to peer, business to business collaboration.  This is the complementary problem to BPEL the folks in the W3C Choreography group are tackling with CDL. Taken from  Edwin Khodabakchian's blog where he posted a link to a broadcast  that was hard to resist last night.  As he notes, Scott Woodgate is a heck of a presenter - someone who clearly knows his story. comment [] 10:21:21 PM

Kids, Grades and Exercise The San Francisco Chronicle had an interesting, likely purposeful juxtaposition, of stories on the front page today: Outcry at schools -- sports dropped - Sports programs were dropped for budget reasons as an West Contra Costa school More schools making the grade - More Bay area kids are scoring better on state tests Poor diet killing more in U.S. - Bad eating habits and physical inactivity are overtaking tobacco as leading cause of death in the US I guess the conclusion is kids are getting smarter from all that studying but perhaps by doing less sports but their lifespans will be shortened because of all that inactivity.   Go figure. These things start seeming more relevant when you have kids.   Fortunately, my six year old daughter doesn't seem to have inactivity on the brain quite yet.  She is currently whipping me into shape by getting me into having jump rope contests at every spare moment I have.  Anyone whose tried "hot peppers" as she calls them - skipping as fast as you can until either you trip or fall down from exhaustion - will know that it's either a quick way to get  a coronary or an amazingly intense workout in 30 second to 1 minute intervals.   comment [] 9:35:30 PM
