OpenFn Prototype for MSF LIME Project

Automating data exchange workflows between DHIS2, OpenMRS, and Open Concept Lab (OCL).

Note that commits to main will be auto-deployed to the connected project configuration hosted on OpenFn.org. Always work on a branch and submit a pull request when ready to release!

Working with the Repo

1. Clone the repo to work with it locally
2. Locally create /tmp folder locally with a state.json file that you don't commit to github
3. start writing and testing jobs locally with the relevant adaptor

Prototype Design

To prototype automated data exchange workflows between MSF's global DHIS2 system and locally-deployed OpenMRS instances, we implemented the OpenFn DPG for this prototype--specifically the platform v1 hosted on OpenFn.org.

If MSF hopes to pilot this solution with real-world sites, then it may choose to locally deloy the v2 of the OpenFn platform--OpenFn/Lightning. See below for what the proposed architecture might look like for this solution running at scale.

Workflows Implemented

For the LIME-Project, two workflows were prototyped. These workflows leverage the OpenFn dhis2, openmrs, and ocl adaptors (see OpenFn/Docs), and connect with demo instances of the target systems.

Specifications

• See below diagrams for a functional overview, or see the diagrams directory for the technical versions of these diagrams, which also detail the specific API steps.
• See this document for the data element mapping specifications, which detail how specific data points are mapped between systems.
• See this sheet for the test cases used to validate the workflows.

Workflow 1: One-way migration of DHIS2 patients to OpenMRS for the initial setup

This workflow #1 is powered by by the following OpenFn jobs:

• wf1-1-getTEIs.j (using dhis adaptor)
• wf1-2-createPatients.js (using openmrs adaptor)
• wf1-3-updateTEIs.js (using dhis2 adaptor)

See the WF 1 technical diagrams for documentation on the specific API endpoints and operations automated in the job code.

Workflow 2: Ongoing sync of new/updated OpenMRS data to DHIS2 for program monitoring & reporting

This workflow #2 is powered by by the following OpenFn jobs:

• wf2-1-getPatients.js (using openmrs adaptor)
• wf2-2-upsertTEIs.js (using dhis adaptor)
• wf2-3-getEncounters.js (using openmrs adaptor)
• wf2-4-getOclMap.js (using ocl adaptor)
• wf2-5-createEvents.js (using dhis adaptor)

See the WF 2 technical diagram for documentation on the specific API endpoints and operations automated in the job code.

Dynamically exporting mappings from OCL

In Workflow 2, there is a step to dynamically export mapping specifications from OCL via its API.

• See this lime-project collection on the OCL hosted app to view how mappings were configured.
• See below diagram for an overview of how this works. For the prototype, this was implemented for the attributes Entry triage color and Final diagnosis (data that is collected when new OMRS encounters are created).
