Abstract: An approach is provided for determining device compatibility using alerts and information spaces. A link redirector receives a request from a device for a required type of service. The link redirector alerts the device compatibility service and the export control interface about the potential request or stores the request information in an information space while searching for a suitable service for the device. Therefore, the device compatibility service and the export control interface can start preparing information about device compatibility and export control before the information is requested by the service determined.
