First off, i'd like to apologize for my lack of alfresco knowledge as i'm coming from the FileNet world. I'm evaluating whether alfresco is a suitable replacement and everything looks good so far. The only issues i'm having is creating Content Types (Document Classes) and associated metadata properties. This seems really involved in alfresco and wanted to confirm if modifying the xml config is common practice or if theres some admin UI or tool that i'm overlooking. Do I need to adjust how I think about modeling Document Classes/Properties?
