To investigate the many different mappings for any URI within the Open PHACTS platform, there is a specific API method called Map URL. Map URL requires as input a URI, the namespace plus the identifier, e.g. http://www.conceptwiki.org/concept/2e754389-d9d4-4c93-8046-f03722573946.
A restriction on the output can also be added to retrieve only mappings to a specific URI pattern, e.g. http://purl.uniprot.org/uniprot/
Another possibility to explore the mappings for any URI in the system is provided by the Manchester Open PHACTS Server, http://openphacts.cs.man.ac.uk/.
