Transmitting a resource and providing information in a resource in a Digital Rights Management (DRM) interoperable system includes: transmitting the resource in a transport session by using at least two handlers; and receiving from the handlers an event message including identification information of the transport session and information which indicates a transfer status of the resource. In addition, the information which indicates the transfer status of the resource may include: a resource index capable of identifying the resource; and information on a transfer status of a resource corresponding to the resource index. Accordingly, information related to transmission of resources can be easily provided in an event form.
