DMX Platform
➜ Platform for knowledge building, data modeling, and collaboration.
➜ Semantic desktop featuring Bring-to-me navigation for preserving stable visual contexts.
➜ Application server and full-stack web development framework.
For 8 years (2017-2025) the DMX Platform was powering the DMX Systems UG (now defunct). Its Linqa product is built on top of the DMX platform.
DMX Platform is the 5th iteration of the 25+ years running Open Source project "DeepaMehta". Starting with version 5 "DeepaMehta" was renamed to "DMX". At the moment the DMX platform is not actively developed. The final version is DMX 5.3.5. Its successor project is DM6 Elm.
