Out-of-the-box Models

The content repository comprises several content models out of the box for specifying the core content types of an ECM system

1. DictionaryModel.xml -  provides definitions for the fundamental data types, such as d:text and d:boolean. It exposes the namespace URI www.alfresco.org/model/dictionary/1.0 with prefix d.
1. Data-Types are:
• d:text java.lang.String
• d:mltext           org.alfresco.service.cmr.respository.MLText  - possible for one node add multiple language
• d:int          java.lang.Integer
• d:long java.lang.Long
• d:float java.lang.Float
• d:qname org.alfresco.service.namespace.QName
• d:date java.util.Date
• d:datetime  java.util.Date
• d:path org.alfresco.service.cmr.repository.Path
• d:noderef org.alfresco.service.cmr.repository.NodeRef
• d:any java.lang.Object
• d:version org.alfresco.utill.VersionNumber
• d:period           org.alfresco.service.cmr.repository.Period
2. System model - (systemModel.xml) provides definitions for types used by the implementation of the content repository, such as sys:base, sys:root, and sys:reference.
1. Types are:
• <type name="sys:deleted">...</type>
• <type name="sys:base">...</type>
• <type name="sys:descriptor">...</type>
• <type name="sys:container">...</type>
• <type name="sys:store_root">...</type>
• <type name="sys:reference">...</type>
3. ECM domain model - (contentModel.xml) provides definitions for types influenced by the CMIS and JCR standards, such as cm:folder, cm:content, cm:versionable, and cm:auditable.
1. Types are:
• <type name="cm:cmobject">...</type>
• <type name="cm:folder">...</type>
• <type name="cm:content">...</type>
• <type name="cm:dictionaryModel">...</type>
• <type name="cm:link">...</type>
• <type name="cm:savedquery">...</type>
• <type name="cm:systemfolder">...</type>
• <type name="cm:authority">...</type>
