Client for the Open Citations Corpus http://opencitations.net/ (OCC)
OCC created their own identifiers called Open Citation Identifiers (oci), e.g.,
020010009033611182421271436182433010601-02001030701361924302723102137251614233701000005090307You are probably not going to be using oci identifiers, but rather DOIs and/or PMIDs and/or PMCIDs. See ?oc_lookup for methods for cross-walking among identifier types.
If you’d like to use the OpenCitations Sparql endpoint yourself you can find that at http://opencitations.net/sparql
