Before you share your research data, you should consider what type of access constraints the data may have. While sharing all data openly would be the best option for reaching a broader audience in the research community and promoting transparency with the public, there are many reasons why data use may come with constraints. Often this includes working with personally identifiable information (PII), national security data, or proprietary datasets. Here are a few things to consider when choosing how your data should be shared:
Open Access
Managed Access
Controlled Access
Here are a couple of terms you should familiarize yourself with when considering how your data could and should be reused:
Raw research data is not eligible for copyright protection because it is viewed as a compilation of facts, which cannot be copyrighted. Nevertheless, you can apply licenses, like a Creative Commons license, to regulate how others may utilize your data. It is essential to include a license when distributing your data and code. Even if your funding agency requires you to make your data and code available, a license will specify what future users are allowed to do with it. This can increase the likelihood of other researchers choosing to reuse your data and code, which is advantageous for you.
Licensing data:
Creative Commons (CC) is one of the primary standard license groups for data. There are six different CC license types with a range of restrictions. Open Data Commons also offers a set of legal tools and licenses to help you publish, provide and use open data.
Licensing software and code:
When choosing a license for data and code it is important that the data license is compatible with the license for software and code. For example, a CC license, which cannot be applied to code, may integrate better with an MIT License. Below are resources for finding and learning more about open source software and code licensing.

While raw research data itself is generally not protected by copyright because it consists of facts, there are still important intellectual property considerations when publishing and sharing research outputs.
