Recommendation 1.2
Approved by IPTC on 25 April 2018, available
at www.iptc.org/std/videometadatahub/recommendation/1.2
Specification
Properties
The Video Metadata Hub’s set of metadata properties includes:
- ~ 20 properties describing what can be seen and heard in the video
- ~ 15 properties providing rights related information
- ~ 15 properties for administrative purposes
- ~ 25 properties covering technical characteristics
- ~ 15 structures of properties which are used for properties listed above
Each property is defined with:
- a name
- a definition of its semantics
- a basic data type
- a definition how often it may occur in the metadata about a piece of video
Technical Implementation
All Video Metadata Hub properties can be expressed by these technical standards:
- EBU Core – for metadata in stand-alone documents associated with the video binary
- XMP – for metadata embedded into the binary video file
- JSON – for a stand-alone and light-weight exchange of metadata, e.g. by APIs
Example video files with embedded metadata
A short video about an IPTC event, all properties defined by a version of the Video Metadata Hub are populated and embedded by XMP. The property values reflect the property name to help sorting out what is displayed in a user interface. The video may be downloaded (8 MB) and investigated:
