Video metadata has emerged as critical at all stages of the media lifecycle and regardless of whether one or many organizations participate in its gathering and distribution. As media and metadata become fully digital, tradition ‘silos’ break down, and this is leading to increased complexity of metadata, as models from adjacent fields require mapping to one another, and the potential for metadata ‘bloat’ as organizations attempt to embrace a plethora of working practices and standards.
IPTC (the International Press and Telecommunications Council) has created a new ‘Video Metadata Hub‘ model able to act either as a primary definition for metadata, or for interchange when needed between disparate metadata models. IPTC has a successful track record of high adoption rates for metadata models, for several reasons, such as the imperative for news organizations to exchange data with immediacy, plus the support provided by Adobe and others within market leading software products. See the Video Metadata Hub specification at the link above,
The design goal of IPTC VMH is simplicity: IPTC members along with invited experts converged on a summary set of metadata with practical application. The core VMH group includes contributors from Associated Press, Bloomberg, Reuters, NY Times, Adobe, Getty Images, and several others, including The Media Institute. The model balances effort and utility: simple metadata with a high return.
There are several highly-active moving image metadata communities, with support for de facto and formal standards. For example, IMF (Interoperable Master Format) and DPP (Digital Production Partnership) define standards for film and television contribution, simplifying delivery from producers to broadcasters and OTT services.
Standards concerning copyright are undergoing a new convergence, with W3C and MPEG standards converging, along with sector-specific standards. A sampling of standards and companion elements relating to rights is included here:
