Web Application Open Platform Interface

The protocol was first released as v0.1 by Microsoft in January 2012,^[1] but as of February 2025, the current specification is v14.5. The protocol has been adopted by applications outside of Microsoft, such as by Collabora Online, Google, ownCloud and Nextcloud.^[2][3][4][5]
