A content class is a named construct that is used to characterize objects in one or more namespaces. Content classes use object metadata to impose structure on unstructured namespace content. They do this through content properties.

A content property is a named construct used to extract an element or attribute value from custom metadata that's well-formed XML. Content properties use XPath expressions to identify the metadata of interest. When content properties are indexed, users can use them to find unstructured content that matches structured patterns.

For example, consider the following XML structure that could occur in the custom metadata for multiple objects in a namespace that contains medical data:


The information of interest in this custom metadata consists of the doctor’s name and the patient’s name.

Based on the metadata structure above, you could create content properties named Doctor_Name and Patient_Name that extract the doctor’s name and patient’s name from the custom metadata XML for each object. The metadata query engine could then index objects with this metadata structure by those property values. Using the metadata query API or the Metadata Query Engine Console, users could query for objects that have Doctor_Name or Patient_Name equal to a specific value.

Content properties belong to content classes. Both content classes and content properties are defined at the tenant level. Content classes are optionally associated with namespaces. Through this association, content properties are associated with namespaces.
