RADAR Benefits

Research data

New challenges for institutions and researchers

Researchers, universities and non-university institutions are increasingly required to make research processes and their results transparent, reproducible and comprehensible.

In addition to the recommendations of the German Research Foundation (DFG) to ensure good scientific practice, more and more national and international science policy stakeholders and funders are demanding measures for the long-term preservation, availability and reusability of research data in accordance with the FAIR Principles. Publishers and journals also increasingly demand the independent publication of research data in order to make research results transparent. For the research community itself, research data can also be useful beyond the original research questions.

Researchers, universities and other research institutions must face these challenges. Against this background, RADAR was developed as an independent repository for archiving and publishing digital research data.

RADAR for institutions

RADAR supports reliable and secure research data management, even if own infrastructures or services are missing.

RADAR for institutions - RADAR is more than a tape archive!

RADAR supports reliable and secure research data management, even if infrastructures or services are missing. RADAR makes it possible to manage, archive, share, review and publish research data from completed studies and projects.

As a repository independent of disciplines, RADAR is aimed at institutions...

... which do not yet run their own infrastructure, or

... would like to use RADAR in addition to existing institutional services or established discipline-specific data centres.


Benefits for institutions

The use of RADAR saves resources and costs required for setting up and maintaining an institutional research data repository.


RADAR can be implemented at your institution within a short period of time. The service can be adapted flexibly to any existing workflows for research data management.


RADAR user role and rights management supports delegated administration by the institution and ensures that only authorised users can store, archive and publish research data.


RADAR offers integrated user registration. For institutions participating in DFN-AAI, users can be authenticated with the institutional user ID.

RADAR can be adapted to existing internal workflows for data management and quality assurance. An administrator manages the RADAR workspaces as central access points for researchers. Usage statistics and flexible quota support these processes.


The RADAR user interface is easy to use, allows an adaptation to the corporate design of institutions and therefore provides an institutional view of the research data output.


The RADAR software is modular and can be used via programming interfaces (APIs). The RADAR API can be used for maximal integration into existing infrastructures and workflows. A customised user interface can be implemented. 


The Data Center API allows data to be stored in an institution's data center.


RADAR provides a variety of open interfaces. This prevents a vendor lock-in of customers.

RADAR guarantees secure and format-independent data storage (Bitstream Preservation). RADAR preserves archived data for the selected retention period (5, 10, 15 years). In the case of published data, RADAR guarantees their availability for at least 25 years.


RADAR enables the description of datasets (as well as single files and directories comprising the dataset) with metadata. The RADAR metadata schema is interoperable (DataCite, Dublin Core, and supports the implementation of the FAIR Principles.


The RADAR service and its technical infrastructure are subject to German law. The research data is stored in 3 copies at different geographical locations exclusively in academic computing centers in Germany.


RADAR has had an exit strategy. If FIZ Karlsruhe should no longer be able to operate RADAR, the transfer of responsibilities to another institution and ongoing funding is ensured.


RADAR is currently being certified according to the Core Trust Seal and thus meets the requirements of many publishers and funders for a qualified data repository.

The costs incurred are billed annually and comprise a basic contract fee and usage-based fees. Quota regulations allow customers to define the available storage space in advance, thus limiting the costs incurred.


The one-off payment for published data is compatible with project-based research funding.


We offer discounted prices for large data volumes of more than 50TB.


FIZ Karlsruhe does not pursue commercial interests with RADAR. Rather, we see RADAR's services as part of our mission according to the guiding principle "Advancing Science".

RADAR was developed themed "from the community - for the community" in a DFG-funded project (2013-2016) and now runs as a permanent service. FIZ Karlsruhe - Leibniz Institute for Information Infrastructure operates RADAR in cooperation with other renowned public infrastructures. 


Together with the RADAR User Advisory Council, we are consistently pursuing the demand-oriented further development of RADAR which we started in the DFG project phase.


We strive to integrate RADAR into the emerging National Research Data Infrastructure (NFDI). In doing so, we are following our guiding principle "Advancing Science", which is to promote the development of science by supporting the entire research process.


Our research area "Intellectual Property Rights in Distributed Information Infrastructures" is concerned with legal issues regarding research data management. RADAR benefits from these activities in the form of verified terms of use and licensing agreements. We plan to provide users with assistance, e.g. with regard to licenses, copyright and data protection.





RADAR for researchers

Research data can also be relevant beyond the original research questions they were collected for. RADAR aims to ensure access to and long-term availability of datasets for the benefit of the research community.

To maximise the visibility of your research results, RADAR helps you curate, archive, share, and publish your research data. In addition, RADAR assures that others can find and cite  the research data.


Benefits for researchers

The RADAR metadata schema is discipline-independent and can therefore be used to describe research data from all disciplines.


With RADAR, you can decide which research data can be viewed publicly and which remain archived and only visible to you.

Research data archived in RADAR meets national and international requirements for retention periods and good scientific practice.


The clearly structured roles and access concept allows you to grant single registered users access to your research data.

Research data published in RADAR are automatically assigned a persistent identifier (DOI). This makes datasets uniquely identifiable and easier to cite, find and link to publications.


If research data stored with RADAR should not be published immediately, you can set an embargo period of up to one year. The dataset will then only be publicly accessible after the end of this period.


RADAR supports the review of research data by reviewers or the publisher prior to the publication via a secure, private link.


For each dataset stored in RADAR, a license (e.g. Creative Commons 4.0) must be selected to define the terms of use for your research data.


The metadata of published research data is automatically indexed at DataCite, Google and B2FIND (EUDAT) and offered for harvesting via standardised protocols (OAI-PMH). This ensures maximum dissemination and findability of your research data.

RADAR provides statistics on access and downloads of datasets to help you assess the impact of your research results.


The costs for archiving and publishing research data are transparent and can be calculated in advance. Costs can be included when applying for funding.


RADAR supports the implementation of the FAIR Principles for your research data: Findable, Accessible, Interoperable, Reusable.





RADAR promotes the implementation of the FAIR Principles for research data

By providing the necessary infrastructure for archiving or publishing research data, RADAR also serves the research community in general. Research data published with RADAR can be found by third parties, reused and cited according to the license terms.
The FAIR Principles define measures with which research data can be found, made accessible, interoperable and reusable. Many science policy actors, including research funders, support the demand for FAIR Data.


The RADAR software supports the standardised description of files, directories and datasets with metadata. The metadata are available as validated XML.


The RADAR Metadata Schema defines 10 mandatory fields and 13 optional fields to document the context and generation of the research data.


Each dataset published in RADAR receives a DOI and is automatically registered with DataCite. This makes it uniquely and permanently identifiable and citable and it can be linked to a scientific publication.


The metadata of published research data are automatically indexed at DataCite, Google and B2FIND (EUDAT) and offered for harvesting via standardised interface protocols (OAI-PMH). This promotes the dissemination and findability of the research output.

Research data can be made accessible to others via the RADAR data publication service.


Authorised persons can also grant single registered users access to archived datasets.


Research data can be linked to other resources via persistent identifiers.

The RADAR Metadata Schema is based on the DataCite Metadata Schema 4.0 and ensures interoperability with other data sources.


The metadata schema provides a combination of entries via controlled vocabularies and free text fields. This supports the interoperability of heterogeneous data sets without restricting the specification of discipline-specific features.


DOIs can be used to link published datasets with other sources.

Each dataset stored in RADAR must be assigned a license (e.g. Creative Commons 4.0). This allows data providers to define the terms of use for research data.


The RADAR Metadata Schema provides information on the origin and context of the research data. This enables potential reusers to better understand the research data and assess its reusability.
