Oracle Multimedia Metadata XML Schemas

F Oracle Multimedia Metadata XML Schemas

The metadata methods of the ORDImage object type use XML schemas loaded through the files described here. When Oracle Multimedia is installed, these schemas are registered as global XML schemas in Oracle Database with Oracle XML DB.

XML schemas define the content models for EXIF, IPTC-IIM, and XMP metadata retrieved from images, and are used for writing metadata to images. An XML schema also defines the content model for the object attributes of ORDImage.

Table F-1 lists the metadata XML schemas by .xsd file name, and includes a brief description and the namespace for each schema.
