Research data have a long lifespan, often longer than the period between their creation and the writing of the scientific publication for which they were created. The function and value of the data changes from one phase of the cycle to the next. The concept of research data life cycle is a tool that can be used to map different phases and see how they connect to each other. The use of a life cycle makes it possible to move from a short-term perspective to a long-term perspective in data management.
Developed by UK Data Archive, the Research Data Lifecycle Reference Model defines 6 main steps : Data creation ; Data processing ; Data analysis ; Preparing data for preservation ; Data access ; Data reuse.
Each of these steps consists of several actions to be carried out to ensure proper management of research data.
Uniris has developed a similar vision based also on 6 phases :
Taking these 6 phases into account allows the following aspects to be achieved :
A distinction is made between active research data, the preservation of part of this data (long-term preservation) and permanent archiving and data sharing.

Research data are numerous, varied and very heterogeneous. They can be divided into five categories (André, 2014) :
Depending on their context of creation (capture or production), exploitation, analysis and processing, research data can be of different kinds :
Contained in various media :
All types :
