Metadata Schemata Reference
CAUTIONThe following reference includes information about a particular metadata schemata (in alphabetical order) as well as a list of properties and their definitions.
Dublin Core
Dublin Core metadata provides a standardized set of conventions for describing assets to make them easier to find. In Experience Manager Assets, the Dublin Core describes digital assets including video, sound, images, and documents.
The simple Dublin Core Metadata Element Set (DCMES) contains 15 metadata elements as listed in the following table. Each Dublin Core element is optional and can be repeated. You can add or delete Dublin Core metadata information as you would for media type-specific metadata.
In addition to the DCMES, there are other metadata elements created by the Dublin Core Initiative. See the Dublin Core Initiative for more information.

IPTC
The International Press Telecommunications Council (IPTC) is a consortium of news agencies around the world - one of its goals is to develop and maintain technical standards. The IPTC defined a set of photo metadata standards for images that is almost universally accepted among photographers. These metadata standards were part of the broader standard known as the IPTC Information Interchange Model (IIM) created in the 1990s.
Although the IPTC header information has been mostly superseded by XMP, an IPTC core schema and an extension schema are available for XMP. In image programs, both XMP and IPTC properties are synchronized.
