In the absence of strong intellectual property rights that protect data and databases in the United States, data-sharing agreements work best when they are part of a broader agreement between research partners. An individual agreement on data sharing should not replace the larger agreement between the partners, but complement and support a particular aspect of the broader agreement. A detailed overview of the role of a data sharing agreement within a large company between research partners is available at Data Sharing: Creating Agreements, Paige Backlund Jarquín MPH, Colorado Clinical and Translational Sciences Institute & Rocky Mountain Prevention Research Center. Whatever the type of delivery, the importance lies in its completeness, accuracy and reliability. If the data does not arrive, is delayed, incomplete or inaccurate, any subscriber to the database may be affected. As a result, the database owner is advised not only to obtain effective support services from the data provider that indicate response times and priority steps for “fixed” ones, but also a lump sum compensation clause for non-delivery, delay in delivery and strict rules on liability for data inaccuracy. The explanation of contract 25 highlights the reasons why a data owner/provider would prefer to obtain a license rather than sell it in order to protect its copyright interests in the data and control the use of the data.
