Image Metadata

Image metadata can be used to extract image information directly from an image in a presentation style. Oracle operate with four different image formats that may be stored in an image.

• EXIF – Exchangeable image file format (Exif) is a standard that specifies the formats for images, sound, and ancillary tags used by digital cameras (including smartphones), scanners and other systems handling image and sound files recorded by digital cameras. The specification uses the following existing file formats with the addition of specific metadata tags: JPEG DCT for compressed image files, TIFF Rev. 6.0 (RGB or YCbCr) for uncompressed image files.
• XMP – The Adobe Extensible Metadata Platform (XMP) is a standard, created by Adobe Systems Inc., for processing and storing standardized and proprietary information relating to the contents of a file.
• IPTC – The Information Interchange Model (IIM) is a file structure and set of metadata attributes that can be applied to text, images and other media types. It was developed in the early 1990s by the International Press Telecommunications Council (IPTC) to expedite the international exchange of news among newspapers and news agencies.
• ORA – The ORDImage object type supports the storage, management, and manipulation of image data.
