The Devices and Sensors Working Group and Web Applications Working Group have jointly published a First Public Working Draft of Contact Picker API. This specification defines an API to give one-off access to a user’s contact information while keeping the user in control over which contacts are shared. This new Contact Picker API supersedes the previous attempts to standardize a contacts API at the W3C.
