Virtual Mappa is the original research initiative that led to the development of the DM resource. VMP is a prototype project in partnership with the British Library focused on how medieval maps of the world and related geographic texts may be collected, annotated and networked. VMP is the beginning of a substantial project to develop a truly interoperable resource that virtually collects and displays content hosted across several digital repositories. Work on this project is currently ongoing, with a first cohort of maps planned to be released online in the summer of 2017. For an early summary of the scope of the project, see this British Library announcement.
