Digital Mappa v2.0 (or DM2) is a freely available online environment for creating projects out of digital images and texts.
The premise of DM2 is simple and powerful
If you have a collection of digital images and/or texts, you should be able to produce an online resource that links together specific moments on these images and texts together, annotate these moments as much as you want, collaborate with others on this work, have the content you produce be searchable, and publish this work to others or the public as you wish.
About the project
DM2 was developed under the direction of Martin Foys and his team at the University of Wisconsin-Madison and Dot Porter at the Schoenberg Institute for Manuscript Studies. Funding was provided through a grant from the National Endowment for the Humanities and through UW Madison’s 2020 initiative.



DM2 has support for IIIF Manifests, which allow the users to pull in images from libraries and special collections all over the world. You can also upload your own images from your computer. DM2 will be released as an open source project in 2019. Follow @performantsoft on Twitter to learn more. If you would like us to set up and support an instance of DM2 for your institution, please contact us!
Partnering with Researchers to Make Better Software
DM2 is an example of the type of work we do at Performant. By partnering with academic researchers on grant funded projects, we create new open source tools that benefit the entire community. We can also enhance existing open source software to customize it to your project or simply install it and maintain it for you. If you would like to learn more about us, please contact us, we would love to hear from you!
