This appendix lists the XML schemas used by the metadata methods of the ORDImage object type. When Oracle Multimedia is installed, these schemas are registered as global XML schemas in Oracle Database with Oracle XML DB.
Note:
The schemas in this appendix might not match the code shipped with the Oracle installation. For the final versions of these schemas, use the files provided with the installation.The latest versions of these schemas are available as files located in the ord/xml/xsd directory under <ORACLE_HOME>. To examine the schemas, query the dictionary view ALL_XML_SCHEMAS. In addition, read the documentation embedded within each schema file for more information.
This appendix includes these XML schemas:

Introduction
This is the Oracle Multimedia schema for image metadata stored
in the EXIF format for digital still cameras. This schema supports
tags defined up to EXIF version 2.21
Metadata extracted only from the 0th IFD. For JPEG images, this means
that the metadata comes from the main image in the file. Metadata is not
extracted for the thumbnail image (1st IFD).
Structure
This schema defines a single global element exifMetadata which
contains up to four child elements. Each child element contains tags
from a TIFF IFD directory as defined by the EXIF standard.
TiffIfd contains tags from the TIFF IFD.
ExifIfd contains tags from the EXIF IFD.
GpsIfd contains tags from the GPS IFD.
InteroperabilityIfd contains tags from the Interoperability IFD.
All elements that derive directly from EXIF tags contain a required
"tag" attribute. The value of this attribute is the Tag ID value as
defined in the EXIF standard.
Unsupported tags
The table below lists tags that are defined by the EXIF standard
but which the current version of Oracle Multimedia does not
read from image files. Note that this schema does define data
models for these tags and future versions of Oracle
Multimedia may parse these fields from image files. Those tags
could be represented by documents conforming to this schema.
These tags are from the TIFF IFD
tag 301: TransferFunction
tag 318: WhitePoint
tag 319: PrimaryChromaticities
tag 529: YCbCrCoefficients
tag 532: ReferenceWhiteBlack
tag 273: StripOffsets
tag 278: RowsPerStrip
tag 279: StripByteCounts
tag 513: JPEGInterChangeFormat
tag 514: JPEGInterChangeFormatLength
These tags are from the EXIF IFD
tag 34855: ISOSpeedRatings
tag 34856: OECF
tag 37396: SubjectArea
tag 37500: MakerNote
tag 41484: SpatialFrequencyResponse
tag 41492: SubjectLocation
tag 41730: CFAPattern
tag 41995: DeviceSettingsDescription
tag 42016: ImageUniqueID

ATTRIBUTE DEFINITIONS
-->
<xsd:attributeGroup name="exifAttrs">
<xsd:annotation>
<xsd:documentation>
This attribute group defines a single attribute that is required
for all elements. The tag attribute value is the TIFF tag value
(in decimal) that is the data source for the tag.

<!-- BASE TYPE DEFINITIONS
Base types are formed from the simple XML schema types.
Sometimes restrictions are added.
They are extended with the required "tag" attribute

Introduction
This is the Oracle Multimedia schema for metadata stored in Application
record sets of the IPTC-NAA Information Interchange Model Version 4.
This metadata is often referred to as 'IPTC' tags.
For the JPEG file format, IPTC metadata is parsed from the APP13 marker.
For the TIFF file format, IPTC metadata is parsed from tag 33723.
All tags with string values are decoded using the ISO-8859-1 character
set. The resulting strings may contain characters that are legal in the
character set but are illegal in XML documents. Illegal XML characters
are replaced with the space (0x20) character.
Supported datasets
The following datasets from the application record are extracted.

Structure
The schema defines a number of types, both simple and complex,
to represent some of the IPTC tags. The itpcMetadataType is defined
as a sequence of all the supported IPTC tags. This type is used to define
a single global element that can appear in an instance document.

Introduction
This is the Oracle Multimedia schema for metadata embedded in XMP packets.
The schema provides for a single element from the RDF namespace.
As defined in the January 2004 version of the XMP specification,
this element should be an rdf:RDF element.
XMP is defined by Adobe Systems Incorporated. For more information
about XMP, see the XMP Specification at the Adobe Web site.
