RE: [soa-forum] RE: loose coupling

David,

Thanks for the history and the intent at that time.  It's a worthy
list that seems to have gotten lost in the fluff.

Ken,

 

Continuing this thought - when we original coined the term - we were
particularly differenciating from CORBA and EDI.

 

So - 

 

1) ability to connect and disconnect - no need to be connected 24/7

 

2) no need for overburdening infrastructure to be installed by all
parties

 

3) information exchange related to role, context and purpose - and
flexible on BOTH sides of interchange.

 

4) ability to adapt and change information exchange content dynamically
(agile information)

 

5) ability for delivery / business process to continue across long
periods of elapsed time asynchronously

<snip> While not formally documented, SOA-RA defines the access
to a resource to be loosely coupled if the necessary interactions to use
the resource require the minimum in the way of use constraints.  The
noted constraints include a priori requirements and requirements at time
of access.
