The Okapi modules are deprecated and should not be used.
The Okapi modules launched with Backlight 1, and were quickly superseded by Pangolin. Okapi is available only to holders of a Backlight 1 license, and can be installed via the Backlight Modules page of the admin. We advise using these modules only while transitioning from Backlight 1 to a newer version of Backlight.
Okapi modules are no longer in active development, and support has been discontinued.
