 Dataverse clients in other programming languages include [pyDataverse](https://pydataverse.readthedocs.io/en/latest/) for Python and the [Java client](https://github.com/IQSS/dataverse-client-java). For more information, see [the Dataverse API page](https://guides.dataverse.org/en/5.5/api/client-libraries.html#r).
 
-Users interested in downloading metadata from archives other than Dataverse may be interested in Kurt Hornik's [OAIHarvester](https://cran.r-project.org/package=OAIHarvester) and Scott Chamberlain's [oai](https://cran.r-project.org/package=oai), which offer metadata download from any web repository that is compliant with the [Open Archives Initiative](https://www.openarchives.org:443/) standards. Additionally, [rdryad](https://cran.r-project.org/package=rdryad) uses OAIHarvester to interface with [Dryad](https://datadryad.org/stash). The [rfigshare](https://cran.r-project.org/package=rfigshare) package works in a similar spirit to **dataverse** with <https://figshare.com/>.
