The present disclosure includes a system and method for collaborative information services. A computing system includes a plurality of collaborative information participants [238] interconnected via a communication network [239], each participant having zero or more data sources [240], and a computing platform [224] programmed with query services [226]. Each query service defines one or more queries [227-1, 227-2,..., 227-N] operable on authorized portions of participant data sources [240]. The computing platform [224] is further programmed with indications from individual ones of the plurality of collaborative information participants [238] authorizing some portion of their data source [240] to be available to the one or more queries [227-1, 227-2,..., 227-N] defined by at least one query service [226].
