hi every one
Im using  OpenCMIS Extension  for connecting to alfresco5.0.b repository and developing a web application,now I have two questions:
1-Im using this url:"http://localhost:8082/alfresco/cmisatom" ,I want to know should I always use this url(for example for create folder or uploading) or only when I want to use alfresco custom aspect ?
2- by upgrading alfresco releases,do this web application work correctly or its possible that I faces problems for upgrading my alfresco version
thanks for your guide.

no you should not be using that url with alfresco 5.   The correct URL to use has a version in the url. See the wiki for details.

There is also no need for the open cmis extension on 5.0 which supports cmis 1.1

thanks a lot for your  good Answer
before I used this url :"http://localhost:8082/alfresco/api/-default-/public/cmis/versions/1.1/atom"
But in my test, changing the value of that property did not affect the aspects on the object ,when I changed the url to open cmis extension url ,It worked correctly ,now haw I can update aspect properties by using cmis1.1?
thanks
