OpARA (Open Access Repository and Archive) is the research data repository of the Saxon universities. Digital research data can be archived or published. The service can be accessed via the website https://opara.zih.tu-dresden.de .
Information on how to use OpARA can be found in the top menu bar under “About”.
For general inquiries about archiving and publishing research data, you can also contact the Service Center Research Data.

Digital research data is archived for an initial period of ten years in accordance with good scientific practice. When digital research data is published, it also receives a DOI (digital object identifier) for permanent referencing, is stored indefinitely and can be found and accessed by anyone.

Data is transferred as part of a submission process on the OpARA website. This includes the specification of descriptive metadata, the upload of the data and - in the case of publication - the selection of an Open Access license. (See: DFG: What is Open Access?)

Before the final archiving or publication, a review process takes place in which the submission - especially in the case of a publication - is checked for its formal suitability (type of data, scope and significance of the specified metadata, description and documentation, choice of license) and content suitability (completeness, correctness, comprehensibility of the documentation).
