DM: Tools For Digital Annotation and Linking

Demo page in DM

Digital Mappa (DM for short) is a freely available and open-source online environment for the collection and curation of digital images and texts. The premise of DM 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, and make this work public and searchable with little or no technological fuss or expertise.

The Schoenberg Institute has been a home and a supporter of Digital Mappa since 2013. DMv2, was launched in 2020, and in the summer of 2021 this version was updated with various refinements,  fixes and new features. DM v2.1 is the current version. There are several projects now live in DM

You can sign up for your own DM account at (click on the three dots in the top right corner). The main project site for DM is, please visit there for up-to-date information about the DM project development,  and for instructions for how to set up and use DM for your own projects.

Do you need help? There is a creator guide on the DM website, a video walk-through on YouTube, and every Friday at 12pm Noon EDT you can join Dot Porter on Zoom for the weekly DM Drop-in. Register here for the drop in, the same Zoom link and password will work for all dates. We’re glad you’re using DM!
