The document discusses KBART, a NISO recommended practice for exchanging accurate metadata about content holdings between publishers, aggregators, and knowledge base providers. KBART aims to establish a universally acceptable holdings data format to improve access for users. It is supported by organizations like UKSG and NISO and involves publishers, aggregators, knowledge base vendors and libraries. Adopting KBART standards will help automate the exchange of up-to-date holdings information and reduce the work currently required to manage and translate this data.
