 Today the UK Data Archive still hosts the Relu Knowledge Portal which provides advice on data management, data sharing and preservation to Relu grant holders and applicants, and links to third-party data sources.The Secure Data Service was established and funded by the ESRC in 2009 to help approved members of the research community access data that were previously considered too sensitive, detailed, confidential or potentially disclosive to be made available under standard licensing and dissemination arrangements.The service became fully operational in 2010, before becoming integrated into the UK Data Service in 2012.
