[SOLVED] Install plone restapi from profile

I am trying to install plone restapi from metadata.xml.
All the others gets installed (but not restapi).
Am I missing something here?

<?xml version='1.0' encoding='UTF-8'?>

You are missing the profile- prefix. (Why is this required? I am not sure. Maybe that could be improved in GenericSetup.)

( seems like I copied the line above, which strangely installs)
