Data Citation means references to data, in the same way researchers routinely provide a bibliographic reference to other scholarly resources. Data are often shared, but they are not often cited the same way as journal articles or other publications.
Data citation is important and facilitates access, transparency and reproducibility, reuse, credit for researchers and visibility for the repositories that share data. Repositories can participate by including information about publications that cite the data in DOI metadata. They can also consume data citation information via Event data.
The Scholix initiative is a high level interoperability framework for exchanging information about the links between scholarly literature and data. It aims to build an open information ecosystem to understand systematically what data underpins literature and what literature references data. Read more about Scholix here
