OpenSample is an industry initiative to improve the quality of online surveys through sharing information about respondents' survey participation histories across survey companies. The initiative aims to create an independent database tracked by a trusted third party to consolidate anonymous metadata on surveys taken. This would allow survey companies to query the database to obtain information about their respondents' participation in other panels. Several working groups are formed to handle technical, legal, research and outreach aspects to make the initiative operational by January 2009. Participation in contributing data and using the results is voluntary.
