Why Register XML Schemas for Use with JCR?
XML data can be stored in Oracle XML DB Repository as either file content or user-defined metadata. In either case, the XML data can be based on an XML schema. XML schema-based data is validated against an XML schema that has been registered with Oracle XML DB. By default, the JCR nodes corresponding to XML document content and user-defined metadata are of node type nt:unstructured, a generic node type defined by JCR, even if the XML data is XML schema-based. Oracle XML DB Repository still validates any changes made through the Oracle XML DB Content Connector against the XML schema, but it is not possible to access or specify typing metadata through JCR. However, Oracle XML DB Content Connector lets XML schemas be registered for use in JCR. This causes the content connector to generate JCR node types for the XML-schema simple types, complex types, and global element declarations in the registered XML schema. In exposing XML data as JCR nodes, the content connector determines whether th
