You'll find a 'Request Access' button for datasets where only metadata is provided. The HDX Connect feature makes it possible to discover what data is available or what data collection initiatives are underway. Only registered users have the ability to contact the organisation through the request access module. The administrator for the contributing organisation can decide whether to accept or deny the request. Once the connection is made, HDX is not involved in the decision to share the data.
