Information on M Technology abounds on the Internet. But some of it has fallen by the wayside - too many dead links. We are attempting to sort though all that information to provide a comprehensive set of jumping off points.

If we've missed anything or anyone, please email us at webmaster@hardhats.org. This list was last updated by Sam Habiel in 2023.

M Implementors

Creators of the OpenM and Caché M's, and current owners of DSM, MSM and Datatree M. DSM and Caché are currently used by the VA to run their VistA software. Download free, single-user version of Caché for Windows or Linux and get Caché documentation here

Outside of the VA and IHS, most VistA instances run on YottaDB or its parent code base GT.M (no website). YottaDB runs the largest VistA system in the world in Jordan as part of the Hakeem project. YottaDB is 100% open-source.
