Through the WoRMS Steering Committee, WoRMS has formal agreements with GBIF, Encyclopedia of Life and Species 2000. The WoRMS Steering Committee approves the provision of copies of WoRMS, ERMS, and other databases to third parties upon application. WoRMS has been proposed as the taxonomic data standard for IOC’s IODE network of ocean data centres.

WoRMS is the official taxonomic reference list for OBIS, and has been similarly licensed to over 20 other organizations around the world (see overview below). This register of species names will promote accuracy, eliminate redundancy, and overall serve to strengthen other species initiatives in providing reliable, scientifically accurate information on the web.
