[Building Sakai] RESTful services in Sakai

[Daniel Merino]

Hi everybody.

One of our teachers has asked us how could he retrieve data from their 
sites (specifically Assignments and Gradebook items) for their own 
applications.

I have tried to take a look on REST services, but I have not found too 
much documentation about how to use them.

I understand that the available services are described in 
/direct/<TOOL>/describe, but I'm not able to retrieve nothing but site 
generic XML info.

For example, using /direct/announcement/<siteid>.xml should retrieve all 
the site's announcements but it shows an empty xml document.

And direct/gradebook/<siteid> shows a form to add an announcement even 
without being logged. Trying to get direct/gradebook/<siteid>.xml throws 
an exception.

I'm sorry if this is a simple question, but does somebody know where 
could I find simple use examples of REST services calls?

Thanks in advance.
