The JPEG 2000 file format has an XML Box container that can include any XML data, although DIG35 is suggested. Advantages of Multi Dimensional Databases. Online Data Modeling Training with Erwin!

Metadata for data model and physical database includes length of a field, the shape of a data structure, the name of a table, the physical characteristics of a field, the number of bytes in a table, the indexes on a table, and data definition language (DDL) for a table.

As data flows from the operational systems into the warehouse, it is extracted, transformed, and summarized. More information about the technical standards is available at the Library of Congress Standards site (Library of Congress, 2011a, b). The exchangeable image file format (EXIF) is a standard for embedding technical metadata in image files that many camera manufacturers use and many image-processing programs support. The record shows that the GIMP image-editing program has been used to process the file, which illustrates that embedded metadata expressed in EXIF is only as accurate as the last application that saved the file and may have been altered by several programs before it is added to your digital library. When XMP cannot reliably be embedded in the native file format, as with MPEG-2, the packet is placed in a small “sidecar” file with the same filename and the suffix .xmp.
