An example project starting with Event Modeling and going all the way through to implementation. It’s in Polish but the model and code is in English. A translation should be out in the near future.

This is the first public recording of a talk on Event Modeling. It was recorded at the Event-Driven Meetup in Seattle, WA. James Nugent was presenting on the Raft consensus algorithm that same night.

This is a discussion with Roy Osherove about Event Modeling and Event Sourcing. It gets into details of implementing systems using event storming that are described with event modeling.


These are the upcoming workshops around the globe that are about or include Event Modeling:

Given the global situation with the COVID-19 outbreak, weekly or even daily free livestreams will be available soon. Please check the EventModeling twitter account.

Realtime Board Template

trello example

In the demos of event modeling, Miro Realtime Board is used. If you would like to get started from a small example, you can download the example event model above from here.

Implementation Gist

This script only requires fish shell and a couple of command line utilities to show the above example work. You can find it in a gist here.

Laptop Stickers

You’ll be able to order these straight here for a small fee to cover printing and shipping - it’s being set up right now. But the SVGs are provided as well in case you want to work on the design yourself or send it to your own printer to save on shipping and other costs.
