Project Status: Active - The project has reached a stable, usable state and is being actively developed. R-check rstudio mirror downloads cran version

Client for the Open Citations Corpus http://opencitations.net/ (OCC)

OCC created their own identifiers called Open Citation Identifiers (oci), e.g.,

06180334099-06101759895

You 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
