ODATA RESTful API

Hi, I'm currently reading RESTful API document and I'm getting stuck rather quick. host:port/.../Products That's the example used in the document. But if I install a clean aras 11 SP12, what would the url be, because there's no *.svc file located in any folder of the installation. Also, the documentation mentions: http://host/odata/Part but so far I only get IIS errors, what does host stand for, localhost/InnovatorServer, localhost/InnovatorServer/Server, I can't seem to find the correct one. Also, how would I go about logging in with a user, that part seems to be missing as well. I can see an OAuthServer running in IIS, but I can't find anything about that in the documentation. regards, MB
