The International Press Telecommunications Council (IPTC) released the new Video Metadata Hub Recommendation (VMHub), a comprehensive solution for video metadata management that allows exchange of metadata over multiple existing standards.
The VMHub supports various technical solutions with the key goal of storing and exchanging metadata in a safe and reliable way, with a universal metadata schema.
“Users of videos of different standards told IPTC they need a common ground in metadata for efficient workflows,” said Michael Steidl, managing director of IPTC, at IPTC’s Autumn Meeting in Berlin, during a day devoted to video. “This is what we deliver now with the Video Metadata Hub.”
Diverse video technology methods have made standardisation challenging – the various approaches for embedding metadata and rights information. There are also many different metadata schemas for video, many of them somewhat limiting.
“Organisations and individuals can benefit from implementing the VMHub because it helps to streamline workflows, with guidelines for organising metadata of videos from different sources and standards in a common way,” said Steidl, who is also the lead of IPTC’s Video Metadata Working Group.
Likewise, the VMHub supports workflow, exchange of metadata, and search functions across existing standards, and provides mappings to Apple Quicktime, PBCore, MPEG7, Schema.org, and IPTC’s NewsML-G2.
“The Hub also supports organisations switching from an ‘old’ to a ‘new’ standard by providing a stable metadata schema and gives the ability to search across videos from different standards,” Steidl said.
IPTC’s Video Metadata Working Group – which consists of delegates from news organisations, system vendors and experts in the metadata field – collaborated for two years to review technical elements, rights and administrative information, and metadata terms for describing audio-visual content, to ensure IPTC’s VMHub was a comprehensive solution for video metadata management.
