DISCO is an information integration approach designed to facilitate increased interoperation among Internet resources.  DISCO supports interoperation capabilities involving several types of information (resource descriptions, terminologies, data interoperation, news, etc.). Integration of each of these services is accomplished using service-specific DISCO descriptions provided by each resource and linked from a main "disco.xml" file of the resource. Inside this file there is a list of links to other files or scripts that contain specific information to update NIF resource information. More information about DISCO is available at
