1. A computer program product stored on at least one non-transitory computer-readable storage medium storing one or more sequences of instructions, wherein execution of the one or more sequences of instructions by one or more processors causes the one or more processors to execute a computer-implemented method for generating a relevance value associated with an object selected from a set of objects, the method comprising: examining a set of metadata sources to determine a number of references to the object from each of the set of metadata sources; calculating a relevance value based on a number of references to the object determined from the set of metadata sources, 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; and storing the relevance value associated with the object in data storage.
