Martin Poulter, Oxford's Wikimedian in Reseidence, gives a masterclass in using Wikimedia for digital research. The Wikimedia family of projects includes some projects that are less well-known than the flagship Wikipedia, but highly relevant to the Humanities. Wikidata has facts and figures about tens of millions of items, Wikimedia Commons has tens of millions of freely reusable images, many from cultural heritage organisations, and Wikisource has hundreds of thousands of historical texts. These platforms are not just for sharing text, images and data, but giving them context in the form of metadata and links. They also allow many kinds of query and visualisation. This session reports on progress with using these platforms with research projects in Oxford University.
