@kaynezhang,
Thanks for your reply. I'm new to Alfresco and want to be sure that there is no other way to create a type in a custom content model that doesn't inherit from cm:content because no need to attach or add any content to the organization type although i know that we can keep it empty, and just want to save some meta-data that is related to each organization and call it from Apache Chemistry CMIS. Also please would you explain what you mean with "don't use cm:content property".
