Metadata Standards
Metadata is structured information that describes, explains, or locates the content of digital assets. In the context of digital asset management, standardized metadata schemas are essential for organizing, searching, and exchanging assets efficiently.
Exif
Exif (Exchangeable Image File Format) is a standard that embeds technical camera data directly into image files at the time of capture. It is automatically written by digital cameras and smartphones.
Typical Exif data includes:
-
Camera make and model
-
Date and time of capture
-
Exposure settings (aperture, shutter speed, ISO)
-
GPS coordinates (if location services are enabled)
-
Image resolution and dimensions
IPTC
IPTC (International Press Telecommunications Council) is a metadata standard originally developed for the press industry to describe the editorial content of images. It is widely used in media production and DAM systems.
Typical IPTC data includes:
-
Title and description
-
Keywords and categories
-
Creator / photographer name
-
Copyright and usage rights
-
Location information (city, country)
XMP
XMP (Extensible Metadata Platform) is an Adobe-developed standard based on XML that can embed metadata in a wide variety of file types, including images, PDFs, and videos. XMP is more flexible than Exif and IPTC and can contain custom metadata fields.
Typical XMP data includes:
-
All IPTC and Exif data (XMP can absorb and consolidate metadata from both standards)
-
Custom fields defined by applications or organizations
-
Version history and editing information
-
Color profiles
