Data Management for Research

The Why and How of Data Sharing

Why share data? There are many reasons why you might find yourself wanting to know more about open data, and how you can share your own data:

  • You want to bring more visibility to your research
  • You want to support open science and open research
  • You are required to share your data due to journal requirements or a grant funding mandate
  • Your lab PI requires all lab members to share data openly
  • You just want to share your data!

 

Creating and sharing open data usually entails taking your data and depositing it into a repository where other researchers can download and use your data. While that might sound simple, there are a few other steps to take to make sure your data is as reusable as possible! When you are getting ready to share data, ask yourself the following:

  • Is the data described well (through a codebook, README file, etc.)?
  • Are there any security restrictions or ethical considerations I need to be aware of before sharing this data?
  • Do I have the data saved (preferably) in an open, non-proprietary format, such as CSV rather than XLSX?
  • Am I putting the data into a data repository where other people can easily find it and download it?

 

In this LibGuide, we have provided guidance for helping you answer these questions as you are getting ready to share your data! Check out the Documentation tab of the LibGuide on the left side of the screen to learn more about how to describe your data. To think through any security and/or ethical considerations, check out the section "The Ethics of Data Sharing". To find an appropriate repository for your data, check out the section below on "Data Sharing Platforms"! If you have any lingering questions and would like more advice, email us at data@cmu.libanswers.com and we'd be happy to help!

 

The Ethics of Data Sharing

Before sharing your data, it is important to ask yourself several questions to ensure you are ethically putting your data out there! 

  • Do you have approval by the Institutional Review Board (IRB) to share your data? Generally, you make plans to share your data in the initial application stage and inform your participants of this through your informed consent form. If you did seek IRB-approval for your research and are unsure of your data-sharing capabilities, please visit the CMU IRB website to get more information!

 

  • Does the data include any personally identifiable information (PII) such as full names, Social Security numbers, driver's license numbers, bank account numbers, passport numbers, or email addresses? Any data you make public should be de-identified and include no PII. 

 

  • Can you ensure the data was ethically collected without harming certain populations, including Indigenous communities, LGBTQ+ communities, and communities of various socioeconomic status? 

There are dozens of questions to consider when ensuring you are ethically sharing data. If you want help navigating these questions, contact us at data@cmu.libanswers.com!

Licensing your Data

While most data itself cannot be copyrighted, aspects of data can be. This includes the modeling of the data, the entry of the data, and outputs, fields, and the data that has been created from the raw data. To facilitate the reuse of data, it’s important to make others aware of how the data can be used and attributed by giving it a known license that details its terms of use. 

Licensing your data using a publicly known and machine-readable license allows your data to be shared and reused in a manner that disambiguates a user’s full terms of use of the data. The license informs the user how the data can be reused, mined, redistributed, and whether attribution is required or not.

There is a wide range of licenses that can be used for data. This includes the many Creative Commons Licenses, which range from very open (CCO) to very restrictive (CCBY-NC-ND). Additionally, there are several licenses focused towards software, programs, scripts, and code. These include the MIT License, GNU General Public License GPLv3, and the Apache License 2.0.

When choosing a license, you should consider the type of data that will be licensed, how you want the data to be re-used, what (if any) commercial use you wish to grant, and if you want to receive attribution for your data. Another consideration is whether you want to place your data in the public domain (CCO), which means no restrictions to the user or requirement for attribution. If you'd like more help in navigating which license to use for your data, please reach out to us at data@cmu.libanswers.com!

Data Sharing Platforms

Many of the places where you find data can also serve as data sharing platforms! Check out the resources below for general data repositories: 

 

We can also offer support on finding data repositories for your discipline. Contact us at data@cmu.libanswers.com to get started!

KiltHub: Weaving the Fabric of Your Research

Did you know that CMU has its own institutional repository for scholarly works and research data? KiltHub is our comprehensive institutional repository and research collaboration platform for research data and scholarly outputs produced by members of Carnegie Mellon University and their collaborators. KiltHub collects, preserves, and provides stable, long-term global open access to a wide range of research data and scholarly outputs created by faculty, staff, and student members of Carnegie Mellon University in the course of their research and teaching. Interested in depositing a dataset? Email us at data@cmu.libanswers.com, or check out our LibGuide on KiltHub to learn more!
