DataLinker and the Farm Data Standards are standardisation initiatives of the New Zealand dairy and livestock industries.

The following is from their About page, and you can read more at their website here.

"The Farm Data Standards and DataLinker were developed as separate initiatives to help agricultural data be more accessible for farmers and to be used more effectively by solution and service providers.

More effective use of data through consistent collection, delivery, and access should save farmers time and drive innovative new insights and technology solutions.

The farm data standards were developed with the participation of a wide cross-section of industry organisations, through an iterative process that involved circulation of drafts and feedback from participants. A steering group of industry representatives provided oversight and mandate for the process."
