(13 Feb 2023) The National Information Standards Organization (NISO) today announced publication of its new Video and Audio Metadata Recommended Practice (NISO RP-41-2023), which establishes metadata guidelines for video and audio assets.
Audio and especially video assets are growing in volume, popularity, and use in scholarly, scientific, and professional communities around the world. Libraries are seeing higher demand from their patrons, publishers are developing and extending their offerings, and software developers and other vendors are improving support for media assets in their products and systems. From video abstracts of journal articles to podcasts to primary content and more, video and audio content is an increasingly important component of the academic information industry. However, until now it has been difficult to communicate metadata for academic media assets due to a wide variety of models in use. Different parties in the ecosystem often employ different and potentially incompatible metadata models, causing challenges for collaboration and interoperability, and impeding the dissemination, discoverability, and indexability of video and audio content.
NISO’s new Video and Audio Metadata Recommended Practice will help address these challenges, by providing a vocabulary that enables connectivity between existing standards covering key metadata elements: administrative (e.g., dates, versions, and identifiers); semantic (e.g., subject classifications and keywords); technical (e.g., media type, encoding, and bitrate); rights (e.g., rights owner, licensor, and embargo information); and accessibility (e.g., accessibility features and access).
