Data sharing is often a natural part of the research process; however, your funding agency may require that you share your data or make them publicly accessible. The US Federal Government requires that Federal agencies that fund research develop plans for increasing public access to the results of that research. Comprehensive information on all of these plans can be found at SPARC's Data Sharing Requirements by Federal Agency page.
Before sharing your data, you should also consider not only the metadata you will need to provide along with the data to make it easily understood, but also the intellectual property, privacy, and copyright, or licensing issues to be addressed with regard to the sharing.
When it is time to preserve your data, you will need to carefully consider exactly which components of your research need to be preserved. Answering "yes" to any of the following questions with regard to a particular data file or set of data may indicate that those data should be preserved for the long-term.
In addition, you should also consider whether you will need to preserve multiple versions of a file or whether the most recent version will be sufficient for preservation. It may also be important to consider whether the project is still in progress or whether it is complete. Long-term projects, such as those that involve sampling of a single site repeatedly over months or years, may require periodic preservation of data before the project is actually considered "finished."
A license will define what others may or may not do with your data. You may choose to assign a broad license that allows anyone to do whatever they like with your data, or you may assign a more narrow license that restricts their use to strictly non-commercial activities and requires attribution of the data creator whenever it is used.
The two primary current sources for licenses are Creative Commons and Open Data Commons. If you elect to deposit data into the Stanford Digital Repository (see below), you will have the option to choose any of the licenses below or one of several software licenses. See the full list of licenses available in the SDR.
A number of specific licenses are also available specifically for open source software (OSS). If you are interestesd in an OSS license, choosealicense.com may be of help to you.
The Stanford Digital Repository (SDR), a service offered by the Stanford University Libraries, provides digital preservation, hosting, and access services that enable Stanford researchers to preserve, manage, and share research data in a secure environment for long-term citation, access, and reuse.
Please note that the SDR is intended for use by Stanford researchers only. A valid SUNet ID is required to access our online deposit application.
By depositing data into the SDR you will:
As part of your data management plan, you may wish to preserve your research output in the Stanford Digital Repository. If so, please note the following important information:

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.
The FAIRsharing website has information about some journal requirements and recommendations for data repositories and standards. To talk with us about preparing data for submission to a repository, please contact us.

When you publish information about where others can access your data online, you want to make sure that the information you are giving them will always be correct. If you publish your data online in a place that is not going to be accessible in the future, others may discover that their efforts to find, view, and reuse your data are futile.
Take the example of former Stanford researcher Malin Pinsky. In 2009, Malin published an article in the journal Conservation Biology (see bottom of page for reference). In this article, he provided information about how to find an additional list of sources and a database with citations. These items could be downloaded from a Stanford web site located in his personal AFS space.
This system worked fine until Malin left Stanford. When someone leaves Stanford, web sites within their AFS space are permanently disabled. Because of that, the links in the Conservation Biology article no longer directed researchers to the data they were looking for. Instead, they saw only the message below that access to the site was forbidden. Contacting the site administrator or HelpSU as suggested would not have gotten anyone the data they were looking for.
When the Stanford Digital Repository began accepting data from Stanford researchers, Malin's data files were deposited. They are now available on their own persistent URL (PURL) page. This URL is designed to be persistent, so Malin's data should be accessible here for a long time to come, no matter where he heads to next. (We even got the published ilnk redirected to the PURL!)
If you have data that you would like to make easily accessible to others now and in the future, contact us about using the Stanford Digital Repository.
