When DANS was established by the two Dutch science organizations KNAW and NWO, they assigned it the task of developing a Seal of Approval for data, to ensure that archived data can still be found, understood and used in the future. In 2008 the first edition of the Data Seal of Approval, written by Laurents Sesink, René van Horik and Henk Harmsen, was presented in an international conference. In spring 2009 the Data Seal of Approval was handed over to an international Board. The full DSA assessment process has been peer-reviewed by external auditors.
-- is an institute of the , and is also supported by the . Since its establishment in 2005, DANS has been providing storage of and continuous access to research data in the social sciences and humanities.
The quality Guidelines formulated in the Data Seal of Approval are of interest to data producers and institutions that create digital data, to organizations that archive data, and to consumers of data.
The objectives of the Data Seal of Approval are to safeguard data, to ensure high quality and to guide reliable management of data for the future without requiring the implementation of new standards, regulations or high costs.
The Data Seal of Approval
- Gives data producers the assurance that their data and associated materials will be stored in a reliable manner and can be reused
- Provides funding bodies with the confidence that data will remain available for reuse and their investments will not be lost
- Enables data consumers to assess repositories where data are held
- Supports data repositories in the efficient archiving and distribution of data
The criteria for assigning the Data Seal of Approval to data repositories are in accordance with national and international Guidelines for digital data archiving such asas developed by NESTOR; published by the Digital Curation Centre (DCC) and DigitalPreservationEurope (DPE); and Trustworthy Repositories Audit and Certification (TRAC): . Furthermore the following has been taken into account: and published by the Research Information Network. The DSA Guidelines can be seen as a minimum set distilled from the above proposals.
