One very important piece of metadata when your data goes public, is how to cite your data. The advantage of a persistent identifier (PID) over a normal web address is that the PID always points to the data, even if the data itself has changed location.
Several types of PID exist, such as DOI, Handle, URN, ARk, PURL, etc. It doesn't matter which one you use for your data citation, although DOI is currently the most integrated in automatic citation counting algorithms.
Citations to your data can add to your academic impact. Indicate in your (Creative Commons) license or user agreement that you want your data cited when reused.
Data citations work just like book or journal article citations and can include the following information:
- Dataset title;
- Persistent IDentifier (PID), preceded by the URL.
More information on PIDs can be found at the Netwerk Digitaal Erfgoed (NDE) (voorheen Nationale Coalitie Digitale Duurzaamheid (NCDD)).
Data provides the core of your publication and as a researcher, you are encouraged and/or mandated to store your research data and make it findable and accessible for re-use.
A growing number of publishers provide guidelines on research data management on their websites. You can find this information in sections like ‘data policy’ and ‘data availability’.
Some publishers encourage researchers to provide their data, but it may also be mandatory to upload your data to a repository in order to publish your article. For this, publishers have lists with recommended data repositories on their website (like, for example, Scientific data).
