RE: [soa-rm-ra] A comment on ecosystems

Gets,
Wasn't composability always a holy Grail of SOA? The definition was
always, that you implement services, representing basic functionality,
that are fairly stable and then use orchestrations (BPM) to implement
solutions that are based on these services in a ways, that were not
necessarily envisioned by service creators.

Frank,

I believe we all agree on this, but I think you put it very well.  Our  
discussions have always pushed in the direction of the "appropriate"  
unexpected -- here, I'm differentiating from repurposing for malice or  
illegal profit.  Is there any place where we have limited ourselves?

Ken

P.S. I had a productive discussion with our TOG friends this morning,  
and I'd like to pass this along to them.  It also shows a repurposing  
of something that isn't necessarily within your enterprise.
