An in-place information management system having a management application built on a common data model and configured for asynchronous query-based application of policies on content stored in the disparate data storage systems through a query interface which may be part of a set of integration services. The common data model may be configured based on common architectures of the disparate data storage systems. The query interface may be configured for running a query on a data storage system in response to a search request received by the management application from a records manager and for mapping semantically equivalent keys from disparate data storage systems to a key in the common data model. The query may define a set of records to be treated similarly according to corporate policy on content lifecycle and records compliance.
