+# Definition Research Software
+
+At the moment, there is no single universally used or accepted definiton of research software.
+This is not for a lack of effort.
+A lot of discussions happend and still happen on this topic and so far resulted in a few definitons that all go in roughly the same direction, but put more emphasis on one or the other aspect.
+We are involved in those discussions as de-RSE e.V., but we did not (yet) single out a specific definition, but for the time being collect there what we consider some of the most often used definitions.
+
+## from: “Defining Research Software: a controversial discussion”
+
+A Summary Report of FAIR4RS Subgroup 3 activity and discussion, available on [zenodo](https://zenodo.org/records/5504016).
+
+_Research Software includes source code files, algorithms, scripts, computational workflows and executables that were created during the research process or for a research purpose.
+Software components (e.g., operating systems, libraries, dependencies, packages, scripts, etc.) that are used for research but were not created during or with a clear research intent should be considered software in research and not Research Software.
+This differentiation may vary between disciplines._
+
+This definition was also used in
+
+- the [Amsterdam Declaration on Funding Research Software Sustainability](https://zenodo.org/records/8325436)
+- the [FAIR Principles for Research Software (FAIR4RS Principles)](https://zenodo.org/records/6623556), an RDA recommendation

+## from: “UK Research Software Survey 2014”
+
+Available on [zenodo](https://zenodo.org/records/14809).
+
+_Software that is used to generate, process or analyse results that you intend to appear in a publication (either in a journal, conference paper, monograph, book or thesis).
+Research software can be anything from a few lines of code written by yourself, to a professionally developed software package.
+Software that does not generate, process or analyse results - such as word processing software, or the use of a web search - does not count as ‘research software’ for the purposes of this survey._

+## from: “Research Software – Quality Assured and Re-usable”, a call for proposals to increase the usability of existing Research Software by the DFG
+
+Available from the [DFG](https://www.dfg.de/en/news/news-topics/announcements-proposals/2022/info-wissenschaft-22-85).
+
+_Nowadays, the use of software is an integral part of research work in almost all disciplines.
+Typical areas of application include the generation, processing, analysis and visualisation of research data and, especially in the natural sciences and engineering, the control and execution of experiments.
+If software is developed for this purpose in the context of research, it is referred to as research software._

+## from: “Research Software Sustainability”, a call for proposals by the DFG.
+
+Available from the [DFG](https://www.dfg.de/resource/blob/172676/861b6b46e50aef649ee6634c7a2d0b6a/161026-dfg-call-proposal-software-en-data.pdf).
+
+_In every phase of scientific work, many disciplines use research software, for example to
+generate, process, analyse and visualise research data.
+In this sense, the term “research
+software” refers to the software applications and software libraries specially created for
+scientific knowledge gain._
