#2 Retrieve Moodle course contents

[Héctor Gaspar Humet]

Hello, we have our own elearning system, implemented with PHP, and we want to integrate Moodle as the "back office" part.
The goal is to have Moodle for administrating the site contents (like users and courses) and our application as a "front end" for the users to interact with this contents.
That's why we had in mind to use the Oki middleware for the communication between our application and Moodle.
Until now we have performed several tests and, besides a couple of bugs in the sample code amb the missing implementation of the Guest Role, everything went ok.
We could show user and course information, but we got stuck when we tried to retrieve a course or a course section contents, like a quiz or a web page.
It seems that this functionality is not implemented, neither in the OSID interface and neither in the PHP components of the OKI, and we wanted to ask:

Does it exist some way to retrieve the contents of a course section (like a quiz or a web page)?
In the case where it's not possible, is it going to be implemented in the near future? or is it already implemented, maybe in the Java OSID interface?
We've seen that the UOC (Universitat Oberta de Catalunya) is using this middleware, how can they show the contents of a course? Or are they using directly Moodle, or a propietary implementation for this purpouse?

Thank you very much,
