Installation and usage is described in the DMX documentation:

Note that DMX was formerly known as "DeepaMehta". Starting with version 5 DeepaMehta is rebranded as "DMX". DeepaMehta 5 and DMX is the same; same code, same features, same license (GPL 3 or later).

IMPORTANT: as long as DMX is still beta no upgrade path is guaranteed. That is content you create is not guaranteed to migrate to a later (beta or final) DMX release. Furthermore no DM4 -> DM5 upgrade path exists at the moment.

What can I do with the DMX - The Context Machine?

With DMX you can author, explore and structure networked information. The approach is quite unique, as in Filemaker or Access, since data and data model are stored in the same database and both are under your control at any time. DMX supports learning, knowledge creation, collaboration and communication. Get in touch with us to find out more about the traits that contribute to the unique DMX identity.

Do I need programming skill to use it?

No. You can start creating your first Topicmap without any programming skills. Just download DMX - The Context Machine 4.9.1, unpack the ZIP-file on your computer and follow the readme instructions.

What's the difference between DMX and DeepaMehta?

DMX is the continuation of the open source plattform DeepaMehta originally created by senior developer Jörg Richter. In 2018 our core team founded DMX Systems UG which now manages client projects based on the DMX Platform.

Will my Topicmap not become confusing when I have entered lots of information?

No, because you can easily "clean it up" by hiding Topics and Associations that are currently not relevant. DMX - The Context Machine stores everything in its knowledge base and you can reveal each information at any time - either on the Topicmap you started with or on a new one you created for your new work situation.
