Why is comparison of URIs important?
<< A prime motivator for comparison of URIs is to improve performance in retrieval operations by using caching mechanisms. A secondary motivator is to equivalence resource identifiers in Web descriptions of information structures to allow those structures to be normalized or merged with other like structures, e.g. the merging of two RDF graphs or the merging of two Topic Maps. As far as INFO URIs are concerned there are no associated retrieval mechanisms, and the prime motivator for comparison of INFO URIs is to support the equivalencing of identifiers for information assets.
