[DMP 2024] Generate a project.yaml file from a list of steps

[christad92]

Overview

We are looking to integrate an AI agent that is able to generate a workflow for a user, based on an instructions specifying the required steps and adaptors.

This feature will enable new users of OpenFn (Lightning) to get started faster after registration by entering the steps they need.

The agent will automatically build a workflow can run without error and ready for editing.

Deliverables

• A new service in the apollo rep called gen_project
• The service should take a series of steps as an input, and return a workflow definition as an output
• The workflow can optionally be defined as a project.yaml or workflow.json file
• A demo script which allows the project to be imported to lightning.

To be clear, this work does NOT include any integration on the Lightning side.

Extensions to this work include:

• Generating job expressions to implement the workflow (this likely leverages existing apollo functionality)

Sample Inputs

Below are examples of prompts and their corresponding workflow.yaml for reference and testing.

Demo script

To validate the work, we would like a demo script which lets us easily test various inputs and see them visualised in Lightning.

The demo should be executable from a terminal. It could be a python or bash script. It should not be integrated with the the OpenFn CLI.

The demo should do the following:

• Read in a list of steps from a file, where each line of the file is one step
• Call out to the apollo service (locally, by default, but can take a URL) to generate a project.yaml
• Generate a Lightning project structure on the file system
• Deploy the project to demo.openfn.org

Suggested API

We recommend the following API for the service

JSON input:

{ 
  steps: ["instructions for step 1", "instructions for step"]
  format: "yaml" | "json"
}

JSON output:

{
	files: {
	   'project.yaml': '...'
	}
}

The resulting structure and the files key makes for easy integration with the apollo server.

Background

OpenFn is an open source platform for data integration and workflow automation which can be used via a CLI or a web UI.

Projects on OpenFn can be encoded in a yaml file containing workflows, steps, jobs, triggers and edges.

Key terms

Workflows contains one trigger and one or more steps connected by edges.

Workflows are at the base of users activities and steps related to a objective are built and saved in a workflow.

A step is a task or instruction that users write mostly in Javascript. The output of a step can be anything from sending a text message, transform data, make an API call, send data to an external systems or fetch data from an external system. These jobs are performed with the help of adaptors.

Triggers are useful for nudging workflows to run based on an event or at a scheduled time. Edges connects two steps and determines the order and conditions for the steps in a workflow.

See more details at https://docs.openfn.org/documentation/get-started/terminology

Sample Project.yaml

Below is an example of a yaml file for a project openhie-project which has one workflow OpenHIE-Workflow and 4 steps [ "FHIR-standard-Data-with-change", "Send-to-OpenHIM-to-route-to-SHR", "Send-to-OpenHIM-to-route-to-SHR", "Notify-CHW-upload-successful"]. The trigger is a Webhook event and there are also 4 edges with source_job, target_job and condition variables that guide how the workflow should be executed.

Here's what a list of steps might look like (also pictured in the image below):

• Fetch Referrals From Primero using the primero adaptor
• Send a text message to case officer with telerivet adaptor
• Add patient to DHIS2 with the dhis2 adaptor

When this feature is integrated with Lighnting, here is how a user would use it to generate a workflow.

Building this UI/X is NOT part of this project but the image below is helpful for contributors to understand the mission.

Documentation and relevant links

• Workflows
• CLI workflows
• Web UI
• CLI

This probably needs to wait until OpenFn/apollo#42 is ready before we can take contributions.

Then this project needs:

• An AI module plugging into the AI server that can generate workflows (in python or JavaScript)
• A CLI integration which allows the module to be called from the CLI and outputs workflow.yaml to disk
• A UI in Lightning, which is probably a separate ticket in the lightning repo

Hey !

I'm interested in contributing to this project to solve the generation of workflows.yaml file.

@josephjclark I would love to talk and get more specific details on it and contribute

Hi @hiteshbandhu thanks for the interest. Please can you send an email to ayodele[at]openfn[dot]org and we will be able to decide on possible next steps.

Hey @christad92
i am interested in working on this project should i mail w=you regarding the next steps?

@christad92 hi,
I am learning coding... Pls let me know whether I can join this project.

Do not ask process related questions about how to apply and who to contact in the above ticket. The only questions allowed are about technical aspects of the project itself. If you want help with the process, you can refer instructions listed on Unstop and any further queries can be taken up on our Discord channel titled DMP queries. Here's a Video Tutorial on how to submit a proposal for a project.

@christad92 i would like to work on this issue can u pls assign me this so that i can start working

[Saksham0303]

Greetings @christad92,
I've sent you my proposal via email. Could you please take a moment to review it and provide any feedback or suggestions for improvement. Once finalized, I'll be ready to submit it on the website.

[Pin4sf]

Hey @christad92 and @josephjclark
I'm Shivansh, and I've been selected to work on this issue for DMP 2024.
I've been developing a Python module to generate YAML files from workflow steps using NLP, rule-based parsing and NER.
You can check the initial AI pipeline I am following.

You can find my initial YAML generator implementation in this Google Colab : RB+NER_Yaml.ipynb

This probably needs to wait until OpenFn/apollo#42 is ready before we can take contributions.

Then this project needs:

• An AI module plugging into the AI server that can generate workflows (in python or JavaScript)
• A CLI integration which allows the module to be called from the CLI and outputs workflow.yaml to disk
• A UI in Lightning, which is probably a separate ticket in the lightning repo

I've also reviewed @josephjclark's comment on the issue thread and wanted to confirm if my primary task is developing the Python module for this issue. Additionally, I noticed the initial framework for Apollo service calls in the CLI and wanted to know if I should also contribute to the UI ticket on the lightning repository.

• A CLI integration which allows the module to be called from the CLI and outputs workflow.yaml to disk

On inspection of apollo repository I noticed that you have set up the initial framework for making calls to Apollo services through the CLI. So need a clarification regarding the integration/plugging of this issue in Apollo repository and CLI calls.

I hope it aligns with the project goals, I would greatly appreciate your feedback and guidance on any potential improvements or clarifications on my responsibilities.

Best Regards

P.S : I think this issue should be in OpenFn/apollo.

[josephjclark]

Hi @Pin4sf!

Sorry for the late reply - and congrats on getting the ticket!

You are not expected to contribute to lightning as part of this project - the focus is on the backend, likely python.

A lot has changed since we created this issue and we're doing a little bit of planning to accommodate that. Unfortunately I'm super busy this week so we need a few days to prepare.

We're going to set up a kick-off call late next week to go through this. We'll be in touch soon to get that arranged, then we can let you loose!
