What is GEMMA?

GEMMA is an initiative of the Dutch Government to provide municipalities with a reference architecture. With this they can improve their digital infrastructure (IT Services).

Create your Digital Municipality Architecture

For any organization it is now very easy and quick to do, to create their own Digital Architecture. Dragon1 provides various visualization templates like this on the platform.

In the embedded viewer above you see an example visualization from GEMMA. It is being generated from a JSON structured data file (.dragon1 File).

You can download that .dragon1 file here. Edit it in Notepad. And upload it in the Viewer here, to see your version of your Enterprise Architecture atlas.

If you want a more advanced interface for creating and editing an architecture atlas, create a trial account here, login and go to the Visual Designer.

Fast, Easy, Nice and of added Business Value

Dragon1 saves you a lot of time with this way of generating architectural insights and overviews. Every manager, architect, contractor or analyst is more productive using Dragon1.

You will spend more time with stakeholders collecting the correct data for your architecture, and less time behind the software.

And instead of creating static diagrams for managers, you provide them with an interactive diagram that they can tune to whatever their need is.


Below is an example of an application function model that has application functions highlighted in planning and implementation. You can do this yourself by using the button in the diagram. With this, you turn an architecture diagram into a visual management report.
