Imagine the following case…
I create a new model with new content types and new content aspects. This is a xml file named alphaModel.xml which I put within C:\alfresco\tomcat\webapps\alfresco\WEB-INF\classes\alfresco\extension. After I create the alpha-model-context.xml in the same folder.
I read your data dictionary guide. But how can I know if my model is integrated ?
