Mozart

Mozart is an open source BPM platform. It is written in Elixir and is in the early stages of development. Currently, process models are defined using a set of Elixir structs providing a modelling language which is somewhat inspired by AWS Step Functions. See AWS Step Functions.

In the future, the intent is to provide a text-based BPM modelling language that is highly readable by process experts with no programming experience.

The modeling elements currently supported are:

Element Type	Description
User Task	Performed by a user
Service Task	Performed by calling a service.
Subprocess Task	Performed by calling a subprocess.
Timer Task	Waits for expiration of a timer.
Receive Task	Waits for a subscribed PubSub event.
Send Task	Sends a PubSub event.
Decision Task	Perform by evaluating a decision block (Tablex)
Exclusive Gate	Selects one of many process paths.
Parallel Gate	Initiates two or more process paths.
Parallel Join	Sychronizes on completion of two or more process paths.

Installation

The package can be installed by adding mozart to your list of dependencies in mix.exs:

def deps do
  [
    {:mozart, "~> 0.1"}
  ]
end

Major Todo Items

Code clean up.
Performance testing (probaly compared with Camunda since I am familiar with it.)
Develop a textual business processs modeling language with will be translated at runtime into native Elixir data structures. The language will be highly readable to process modelers with no programming experience.
Develop GUIs for:
- Runtime trouble shooting and monitoring.
- User and group administration.
- User task assignment and execution.

Providing Feedback

If you have questions, comments, suggestions, etc. feel free to open issues in GitHub.

Collaboration

Yes, it would be great having other developers join the effort (and discussion).
