cProject suite - Q

Hi

Our customer has just implemented WAS640 and cProject 310. From an ABAP/Technical point of view how do cProject/cFolder store data in WAS640?? Is it all stored in XML like DB? I understand that the manipulation with cFolder data happens from a portal but is the data stored in WAS640 and where?? Can someone give me links to the methods/objects that must be used to access the cFolder data.

Really would appreciate any help here.

Cheers everybody ;O)
