An object-linking interface for a computer system dynamically links a selected target object within an host application with a second user application. The operating environment includes a plurality of means testers, each of which is associated with a specific user application, and an object mapper. The means tester is passed a copy of the target object and tests the suitability of the associated application for processing the target object and generates a corresponding likelihood score. The object mapper queries each means tester to obtain the likelihood score and identifies, based upon said likelihood score, one or more applications suitable for processing the target object. The object mapper may automatically launch the recruited application or may allow the user to select a recruited application from among a list of candidates. The target objects is then passed to the recruited application for processing.
