Collaborative Lifecycle Management (CCM, QM and RC) Web Service architecture and web services

Hi there,

I am a beginner of CLM and am going to call web services of CLM to handle such functions below.
(1) Search project areas under some conditions. The project areas include the ones under CCM, QM and RC.
(2) Extract project area necessary information as project template, so that users can apply the project template for new project area.
(3) Create project area using existing project template.

As I have not any idea about CLM for now, in order to finish those functions, could someone please provide any hints? How could I start from? What material can I reference to?

In addition, does CLM provide unified web service to manage project areas under CCM, QM and RC? Is there any relationship for project areas under CCM, QM and RC? I tested to create a project area under CLM and found there are three project areas actually. Is there any parent project area in CLM, which has relationship with the project areas under CCM, QM and RC? I think I don't have any idea about the architecture either.

Thanks in advance!
