1. A method for use in an information management system in which multiple models are utilized to characterize stored information, the method comprising the steps of: receiving a query directed to the stored information; determining at least one contextual indicator from the query; applying said at least one contextual indicator to a meta-model including a plurality of linkages between attributes of respective ones of the multiple models, each of said linkages comprising one or more associated contextual properties, to generate a transformed meta-model specifying an authoritative policy result for processing the query responsive to said at least one contextual indicator; and processing the query in accordance with the authoritative policy result specified in the transformed meta-model for the at least one contextual indicator; wherein different contextual indicators are associated with different transformed meta-models which specify different authoritative policy results to be applied when processing a given query; wherein a given one of the plurality of linkages of the meta-model has two or more policies associated therewith and the transformed meta-model specifies a given one of the two or more policies as the authoritative policy result; and wherein the steps are performed at least in part by a processing device comprising a processor coupled to a memory.
