The Alphabet of Automation
Using XMP, this metadata is attached to and travels with the photo file throughout the production process. Whatever changes occur to the asset will be saved along with it, making certain the correct version is in use.
Even if the original file is converted to another file format, such as an EPS, PDF, or Photoshop file, the metadata is preserved, maintaining the information trail throughout the production process.
In addition to carrying a wealth of descriptive information, XMP-empowered files are searchable. Simply being able to deeply and accurately search for assets using a computer's standard search functions can become a reliable method of asset management, without requiring additional software.
XMP lets users assign multiple levels of descriptive metadata that's understood by XMP-compatible applications, including Adobe InDesign CS, Acrobat 6.0, Photoshop CS, Illustrator CS, and others.
XMP labels provide the meaning that guides interoperability of applications, and can be used to establish field values for databases—attributes important to publishers who need to control an increasingly overwhelming amount of digital content. These same attributes are beneficial to corporate IT departments, for archiving and other purposes.
Job Definition Format, or the 'JDF', is authored by Adobe, Agfa, Heidelberg, and MAN Roland. It's based on the eXtensible Markup Language (XML), an open Internet standard document markup language.
JDF streamlines the production workflow, and integrates business operations that span the entire printing enterprise. JDF enables more than automatic reporting of job information to accounting, or job status to production.
JDF interacts with JDF-compliant devices. For example, a PDF file might contain several EPS or TIFF files. XMP provides key information about the color space and resolution. The JDF file can refer back to the XMP information for color conversion, trapping, or printing requirements.
