On June 15, 2010, OCLC released a statement entitled: OCLC Policy Statement on RDA Cataloging in WorldCat for the U.S. Testing Period (available at: http://www.oclc.org/us/en/rda/policy.htm)
Catalogers who are familiar with RDA rules may begin to contribute original cataloging to WorldCat using RDA, or wait for the results of the RDA testing. All RDA records should be coded 040 $e "rda" and "$b eng". To see sample RDA records in WorldCat, RDA records may be searched via the new OCLC index: Descriptive conventions (label "dx:" in the Connexion Browser).
