ONIX (Online Information Exchange)

ONIX (Online Information Exchange) is an international industry standard used by book publishers to exchange product metadata electronically throughout the supply chain. This open-source specification is based on XML. Publishers use ONIX to submit catalog information and manage book metadata effectively. The standard is developed and maintained by EDItEUR, an international group. ONIX helps enrich product metadata and catalog quality, facilitating better integration with platforms that use it. Publishers need to use third-party software for uploading ONIX files to designated servers, and it covers various fields crucial for product listings on commercial platforms.
