15. A computer processing hardware system for generating a stored relevance value associated with an object selected from a set of objects, the system comprising: a metadata extractor that examines a set of metadata sources to determine a number of references to the object from each of the set of metadata sources; and a relevance value calculator that calculates a relevance value based on a number of references to the object determined from the set of metadata sources, and stores the relevance value associated with the object in data storage, wherein the set of metadata sources is ranked according to one or more priority factors, and calculating the relevance value comprises associating a weight factor with each of the set of metadata sources, calculating a weighted number of references for each of the set of metadata sources by multiplying the number of references determined from a metadata source by the weight factor associated with the metadata source, and calculating the relevance value based on a weighted number of references to the object determined from the set of metadata sources.

The computer processing system of claim 15 wherein the metadata extractor comprises: an object entity parser that determines references to the object by analyzing metadata from an application data framework (ADF) entity; a descriptor parser that determines references to the object by analyzing metadata from runtime code configuration descriptors; a database parser that determines references to the object by analyzing metadata from a database configuration; and a source code parser that determines references to an object by analyzing metadata by parsing source code object definitions.
