Licensing
Licensing is an important aspect of practicing Open Science.
By applying licenses to your research data and to other research outputs, you remove any ambiguity over what others can - and cannot - do with your work.
Why you should licence your research data
Licenses allow your data to be shared and re-used under flexibly, legally sound terms: it lets potential users know how it can be re-used, mined, combined, broken-up or re-distributed. Any research output (including datasets) is not considered open access if it is simply made available on the internet with no licence; one of the key tenets of open access is that potential users should be able to understand how they are permitted to use an output and whether they need to seek permission for their intended use.
There are many reasons why releasing data can be in a researcher’s interest including:
- It has the potential to increase the impact of research, not only academically, but also economically and socially.
- The availability of the data alongside associated tools and protocols increases the efficiency of research by reducing both data collection costs and the possibility of duplication.
- A significant number of research funders now require data produced in the course of the research they fund, to be made available for other researchers to discover, examine and build upon. The Jisc Open Policy Finder tool summarises open access policies of a number of research funders.
For funders not available on the Jisc Open Policy Finder tool, researchers should consult the funder’s webpage and the conditions of their grant award.
What open licence options are available to me for my research data?
You have the option of creating a bespoke licence for your research. However, writing a bespoke licence for your data is not a trivial undertaking and it is almost certainly unnecessary in the light of standard licenses that are available.
There are two sets of standard open licenses particularly relevant to your research:
You should use a licence from one of these sets rather than creating your own licence, for three reasons:
- It is less work (organisational efficiency and cost saving)
- The use of standard licensing terms can lead to greater interoperability of data
- Increased user awareness of licence terms and therefore better compliance.
Open Data Commons has produced three open solutions specifically for data, datasets and databases.
However, Creative Commons licenses are fast becoming one of the most used and recognised standard licenses for providing access to data and other resources.
How do I make good decisions about open licences?
Different elements come together to inform your decision regarding your choice of open licence for research data:
- Are you the sole creator (and can make your own choice)?
- Do you use third-party material with existing rights?
- Does your research funder have a policy relating to open data?
When given a choice, generally researchers can tend to choose licences conservatively. The University does not prescribe the use of any particular open licence for research data. The most appropriate licence will depend on the nature of the material and related requirements.
However, the Creative Commons Attribution Licence (CC BY) is widely used for the licensing of datasets and is a good choice that will suit most requirements. Increasing numbers of funders and publishers are mandating that any licence applied to a dataset be no more restrictive than CC BY. If you deposit in PURE Datasets, we will encourage you to use the CC BY licence. There is one exemption: CC licenses are not suitable for licensing software.

Applying an open licence to your research data
Open licenses, code, and tools are available to the public free of charge, without obligation. You do not need to register to apply an open licence to your material; it is legally valid as soon as you apply it to any material you have the legal right to licence.
Ulster University have developed a short guide ‘How do I apply an open licence to my research data?’ see this guide for further support.
Open licenses are irrevocable
It is important to bear in mind that open licenses are irrevocable. Once you apply a CC licence to your material, anyone who receives it may rely on that licence for as long as the material is protected by copyright and similar rights, even if you later stop distributing it.
It is therefore important to be clear on your options for choosing an open licence before attaching an open licence to your work.
Creative Commons Open Licenses and other research outputs
This open licence guides developed for this page have been specifically written to guide you through a process of selecting and applying an open licence to your research data.
However the overview of Creative Commons Attribution Licenses contained within these guides is relevant to all research output. If you would like a brief overview of the various Creative Commons Attribution Licenses read Help with choosing an open data licence for your research data.

The impacts of licenses which are not fully open
Open means anyone can freely access, use and share for any purpose (source: Open Knowledge Foundation). This means while lots of licenses aim to be "open", the terms they include may fall short of actually being "open" data, or can make reuse of their data very difficult. The Open Data Institute's article 'What are the impacts of non-open licences?' explains some common licence terms and outlines consequences for the reuse of data in applying licence terms such as 'non-derivative', 'non-commerical' and 'sharealike' requirements.
An important note on licensing your software
Creative Commons licenses should not be used for licensing software because they were not designed for that purpose. Instead software developers should use appropriate licenses like those collected by the Open Source Initiative or Free Software Foundation. You can check your options at choosealicense.
The University of Bristol have attempted to address some common questions that academics and researchers have about licensing software as open source through a short document on Open Source Software Licensing FAQs.
