Re: [alf-dev] Article about BPEL

[Daniel Gross <gross@xxxxxxxxxxxxxxx>]

Hello Tim,

It appears to me from your respond that the actual objective of 
designing ALF is to obtain a standardized set of WSDL interfaces 
(structure + behavior + vocabulary), which should guide the 
implementation of systems, which enact service flows amongst Enterprise 
application development tools. In this sense one prime objective of the 
ALF framework appears to become a ALM standard, and designing the ALF 
framework means coming up with workable and viable interface standards, 
that applications and execution engines can adhere to.

Can you agree to that observation?

thank you,

Daniel

p.s. BTW, I am still following the ALF project for my research ... just 
more in the background ...
