The largest international dairy data partnership, bringing together milk recording organizations and national databases across thirteen countries representing approximately 200,000 dairy herds, 20 million dairy cows in total and 13 million milk recorded dairy cows, was launched in November 2020. The International Dairy Data Exchange (iDDEN) is aimed at streamlining data exchange between dairy herds, milk recording organizations and dairy equipment manufacturers as well as other dairy related organizations.

iDDEN was established to operate as a non-profit organization by seven groups providing dairy data services in Australia, Austria, Belgium, Canada, Denmark, Germany, Iceland, Finland, Norway, Sweden, The Netherlands and the United States.
