Mapping StreamServe documents types and metadata to Enterprise Library Before you can map document types and metadata The following steps are required: • Create the document type in Design Center, export, and deploy the Project. • Create a connection to Enterprise Library, see Setting up connection profile for Enterprise Library. • Link the connection to the application domain, see Linking the Enterprise Library connection profile and application domain. ELS must also contain document models and properties that correspond to the document types and metadata used by the StreamServer application.
