Embodiments of the present invention address deficiencies of the art in respect to managed object expression and provide a method, system and computer program product for algebraically expressing a managed object in a keyed data set. In an embodiment of the invention, a method for algebraically expressing a managed object in a keyed data set can be provided. The method can include specifying one-dimensional sets of managed objects each with a corresponding single partial object identifier with wildcard and incorporating each single partial object identifier with wildcard into an algebraic expression compositing managed objects in the keyed data set. The method further can include evaluating the algebraic expression to generate an index for the composited managed objects in the keyed data set, and managing the composited index in a computer communications network by reference to the index.
