Project completion

The question arises at the conclusion of your research project of what is to be done with your research data. Various options are available for publishing research data to make them available to third parties, depending on their value and subsequent usage potential. You should consider properly archiving your data to ensure that your research results remain comprehensible and reproducible, in accordance with good scientific practice.

Publications and Data

  • Why should I publish my data?

    There are a number of reasons why it is recommendable to publish research data, including enhanced reputation through heightened visibility of academic achievements, for example throughout citation and continuing usage of your research data by third parties. Publishing underlying data is good scientific practice because it affords transparency and renders research results reproducible. Academic dialogue and partnerships are strengthened by the sharing of research data, potentially having a greater impact on societal debates and political decision-making as a result. The open science argument is often heard that the results of publicly funded research should be publicly available, as a rule, and third-party funding contributors are increasingly calling for the publication of research data in the absence of compelling reasons otherwise.

    There are of course cases where your data should not or may not be published, such as if they are copyright-protected, subject to confidentiality or contain personal data. Such problems can be eliminated upfront however in some cases through careful project planning (see Project planning). Thus as early on as possible you should clarify any relevant legal issues with your project partners and other stakeholders, obtain informed consent declarations and plan strategies for anonymizing your data (see Legal issues).

  • Repositories, data supplements and data journals

    Data Repository

    In publishing your data you should follow the FAIR principles , so your data can be drawn upon and cited by third parties. According to these principles, data should be findable, accessible, interoperable and reusable.

    Most data are published in repositories, which has the advantage that the data can be found outside of text publications via certain search engines and cited as separate data publication. We recommend as a rule that you contact a discipline-specific repository that specializes in the data formats and metadata standards specific to your field and affords maximum visibility within your academic community. And many institutions have their own repositories their researchers can use. At the University of Bonn you have access to the RADAR servcice for the archiving and publication of research data from all academic disciplines. Other general repositories may be used as well in addition to RADAR for publication of an array of data types. Please see our discipline-specific advisories on identifying suitable repositories.

    Academic journals are increasingly offering the option of attaching research data as a file attachment or supplementary material to an article. The advantage is that the data are then published along the article all at once without having to worry about meeting the requirements of other platforms. The conformance of data thus published with the FAIR principles depends on the extent to which such conformity is ensured by the respective journal or publisher.

    Additionally, data journals are now increasingly being seen as the gold standard for data publication, allowing a peer review process which can document the quality of your research data in a published data paper. Data papers are particularly beneficial for demonstrating outstanding data quality and high reusage potential, but not all academic fields have suitable data journals at this time. A list of the existing data journals is provided at

  • Data preparation

    It is important to prepare data prior to publication to enable interpretation and further usage of the data by third parties. The preparation process starts with selection and curation, determining what files in what versions are to be included in the publication and which are not. The subsequent usage potential of the data should be the primary selection criterion. In addition to using the data collected to pursue further research questions, you should consider other usage scenarios as well. Could your data be of interest for teaching, for example, or do you have materials that could be beneficial in terms of methodology (survey methods, questionnaires, analysis techniques, visualization scripts, etc.)? Data quantity is another selection criterion, as publishing large datasets can involve considerable cost.

    All data you publish should be documented comprehensively to enable third parties to transparently understand it on their own without having to even read your paper, if possible. Please note as well our data documentation advisories.

    Has it been determined whether the data are subject to copyright or exploitation rights? Once any necessary consent declarations been obtained and personal data rendered anonymous (please note our advisories on legal issues), check your data based on formal criteria such as date and number formats, value scales, field and variable naming conventions, abbreviations, spelling errors, and so on. Also look for any extra spaces and special characters, because these are notorious for causing errors in automated data processing.

Upon conclusion of your project, the question arises of what to do with the research data. According to the DFG`s precepts of good research practice, data must be retained for at least ten years to fulfill the requirements of verifiability and transparency in academic research. Also, a well-thought-out archiving concept will benefit you if you take up that research again in future. Research data should be archived along with descriptive documentation, as well as any preliminary results and processing tools. Data are generally archived irrespective of whether some of the data have been made available in publication form. This does not mean however that you always have to archive all files and file versions. As with publication (see above), archiving too requires data selection and curation. Generally, you yourself are the best judge of what data should be archived in what form to meet documentation requirements.

Do not archive your data on a USB stick in your desk drawer! Different archiving strategies are recommendable based on the scope, format, content and sensitivity of the data concerned. The simplest possibility is to keep the data yourself, but if you do so then you should store it on at least three separate data carriers kept in at least two different locations (see also Storage and Backup Strategies). Please be aware that storage media have a limited useful life. You should encrypt your data carriers to rule out the possibility of misuse of the data. We recommend that you store an additional copy of your data on the University of Bonn file service infrastructure (see section on Storage and Security).

In addition to such solutions for handling storage yourself, a number of data repositories are available (see above) offering professional archiving services, some of which are geared for long-term archiving. Graduate students and faculty of the University of Bonn also have the option of archiving data for up to 15 years via the RADAR-Service . The service allows you to decide what parties can have access to your data. Other repositories afford a higher level of security for sensitive data requiring greater protection against unauthorized accessing.

In addition to simply storing datasets so as to protect them from being compromised (bitstream preservation), archiving research data involves challenges arising from continuous changes in operating systems, software environments and data formats. Files you save today may not open at some point in the future because the necessary software is no longer available or installable, or because the format is no longer supported. There are two measures you can take however to minimize this risk of data loss. (1) Documentation: the more detailed you describe the software environment (tool version, add-ons used, operating system, etc.), the easier it will be to restore the data if necessary. This is especially important if you use specialized software not widely in use. (2) Data formats: use a data format for storage that is as open and standardized as possible (see also the section Organizing Research Data).Such formats are usually interoperable, i.e. they are much easier to process in differing system environments.
