Data preservation at Stanford

The Stanford Digital Repository

The Stanford Digital Repository (SDR), a service offered by the Stanford University Libraries, provides digital preservation, hosting, and access services that enable researchers to preserve, manage, and share research data in a secure environment for long-term citation, access, and reuse.

By depositing data into the SDR you will:

  • Obtain a permanent, reliable web link (persistent URL) to your deposit that will not change over time
  • Control when research data are made public
  • Establish licensing rules around your data
  • Make your data easy for other researchers to discover
  • Ensure that the information is preserved into the future

Our SDR Quick Guide (pdf) contains helpful information to get your ready to deposit data into the SDR.

For additional information see our FAQ section on repositories and data preservation, which includes questions and answers about the SDR.

SDR Terms of Deposit

SDR standardized language for DMPs

If you do choose to use the Stanford Digital Repository, the following text describing the service and how your data will be safeguarded and made accessible may be copied and pasted directly into your data management plan's section on data preservation.

"Digital content ingested to the Stanford Digital Repository's preservation core is replicated multiple times and stored in geo-diverse locations on different media types. All content is audited systematically to ensure that the bits are maintained exactly as deposited, and a log of preservation actions is kept to help ensure the content's integrity. The repository is built using open-source software widely adopted across the research community, with dedicated staffing by digital preservation experts. Access is controlled using strict authentication policies and enterprise-level security mechanisms. Metadata describing the content is indexed for searching, and copies of ingested content are provided via persistent URLs to authorized users via Stanford's digital library environment."

Note that this language is available within the Data Management Planning Tool, if you opt to use that method for writing your data management plan.

Educational opportunity is an important issue in a democratic society. In the United States, measuring educational achievement and opportunity is complex because the public education system is diffuse. Funding for public education depends on a combination of local, state and federal governing bodies. The variations in funding and community level support for public education and standardized testing makes comparisons and analysis across the U.S. an arduous task. 
This is why the Stanford Digital Repository (SDR) deposit of the week is critically important to note. Stanford University Professor, Sean Reardon and his colleagues have just deposited the Stanford Education and Data Archive (SEDA) into the SDR for long term preservation. This is a data set that includes 215 million test scores and tackles the difficulty of comparing test score data from every public elementary and middle school in the United States for a period of 5 years, (2009-2013). What's brilliant about this collection of data is that, Reardon and his team developed a method to equate the scores across states for comparison enabling a whole new set of questions on educational opportunity to be answered, new stories to be told, and new questions to be raised.
