Structured Citations for the Sum of All Human Knowledge

We are building a structured repository of citable sources that can serve Wikipedia and other open knowledge projects.

Project overview

Verifiability is critical to open knowledge projects like Wikipedia, and citations are central to their success. Yet, methods used to cite information are outdated. Citations in Wikimedia projects are hard to discover, maintain, reuse, analyze, and discuss. The contributor community has long been in agreement that citation management needed improvement.

Efforts are now underway to build a stronger technological foundation for representing sources and managing citations in Wikimedia projects. The introduction of Wikidata marked the beginning of an organized attempt to improve structured citations.

In 2016, we introduced an initiative called WikiCite . Its aim is to grow and support a community of contributors who are invested in creating technological solutions to the verifiability issue. We plan to build an open repository of sources—using Wikidata as the primary infrastructure—that can serve all open knowledge projects, including Wikipedia.

We strive to develop a deeper understanding of how Wikimedia contributors use sources and to improve technological support for sources and citations.
