Content Model and Managed Metadata
“Metadata” is data about data and is essentially the categorization of the content within a content management system. A good example of metadata is in the classification of documents in a content management system (CMS) or document management system (DMS). A proposal document might have some essential attributes associated, aside from the actual content in the proposal document, such as Proposal Number, Client, Date, and so on. These attributes are the metadata associated with the document.
