Legacy Extensions
These extensions were produced in the past and are good examples of desired uses of OpenRefine. They are maintained here for historical reference, and in case a contributor would like to renew them.

Reconciliation services
OpenRefine can connect to several reconciliation services. You can find information about them at:
- Reconcilable Data Sources in our wiki
- Reconciliation Software at the Reconciliation API Census
- Reconciliation Services at the Reconciliation API testbench (generated by a SPARQL query on Wikidata)
