Here are a few ideas of scenarios:

a) a store with a catalog of goods, and a shopping cart app, similar
to the Tuscany store sample;

b) an app allowing you to track the location of your friends, you
build a list of friends, they update their location, and you can query
for the 5 closest ones;

c) a Twitter-like app, you follow a list of people and see the
messages they write.

These three scenarios have pretty different write / read / query
characteristics. We already have REST service examples for (a) in our
store sample. You could just build on that, but if you want more fun,
I think it'd be really interesting to try to come with REST services
for (b) or (c) as well.

Any thoughts from others in the team?

You'll find it there:
http://svn.apache.org/repos/asf/tuscany/sca-java-2.x/trunk/samples/applications/store/

It uses the Tuscany ATOMPub binding. ATOMPub is a good example of a
standard REST protocol.

I think there's a few more REST samples but can't find them at the
moment. Looks like most samples have been moved out of the samples
directory for some reason.

Could the guys working on REST send a few pointers to the other REST samples?

Thanks!

Hi Jean-Sebastian,
I like to try with the Twitter-like app since it will be interesting. Any
comments?
If you can provide me the  location of REST service example for shopping
cart app then I can use it for get some idea from it.
thanks
