If I remember correctly ­ its been a couple of years ‹ the CCI is an
abstraction for a synch resource. The idea was to create an API that any
resource could implement, regardless of its purpose. However, in practice
each type of resource has its own API and usually its easier to work with
that, than a generic abstraction.  I think some vendors have implemented the
CCI for ERP RA adapters, but I¹m not sure about that. Personally, I don¹t
think the CCI adds much value, but I don¹t really care if someone else wants
to implement it.
