hi All,
Can someone point me to some documentation on fragments and how they are
used within SCA?
thanks, johnny

Ah, yes. I seem to remember suggesting that that whole Appendix
should be removed before 0.95 was published on the basis that it
would be confusing but it didn't quite make it out. IMO that whole
section should be viewed as obsolete.
We've been discussing a couple of different packaging strategies on
the tuscany-dev list this week - those threads would be worth reading
if you are interested in packaging stuff.

Sorry, forgot. Pg 50 of the spec has references to fragments, that's where
I got the info from.

There is some coverage in the 0.9 assembly model spec available here:
http://www.osoa.org/display/Main/SCA+-+Previously+Published
+Specifications
Since then though, fragments have be replaced with the concept of
recursive composition which is described in the 0.95 level spec:
http://www.osoa.org/display/Main/Service+Component+Architecture
+Specifications
and
http://www.osoa.org/display/Main/Recursive+Assembly+Model
Fragments are now just composites that are used by other composites
in one of two ways:
* as implementatation, where a component in a composite is
implemented by a composite. This has benefits in terms of encapsulation.
* by inclusion, where a composite includes services, references and
properties from another which is really a way of just partitioning up
the definition (think #include)

The fragment concept is removed by the latest SCA 0.95 spec (draft:
www.osoa.org). Now we have a composite model with include.
Thanks,
