RDF data show their values the most when built in a distributed manner and linked to each other from several aspects with URIs as their keys. However, we have seen several URI mismatches across RDF datasets that should be identical such as the cases of using different prefixes and code systems. In this situation, we need to develop an infrastructure in which these URIs are treated identically by using an URI rewriting dictionary constructed to be tailored to each RDF dataset. Here, we show some examples of these synonymous URIs and propose an architecture to rewrite some URIs when retrieving RDF data from multiple SPARQL endpoints. As a result, users can obtain properties as to a consolidated URI, which otherwise get ones explicitly asserted as triples only
