Open Syndrome Definition - Data Browser

An interactive data browser built with Marimo that lets you filter epidemiological datasets using Open Syndrome Definition (OSD) criteria, powered by the opensyndrome Python package.

How it works

1. Load a dataset (CSV) — use the built-in example or upload your own.
2. Map your dataset columns to OSD concepts via an editable YAML form.
3. Select one or more syndromic indicators from the definitions catalogue.
4. The engine compiles each OSD criterion into a Polars expression and labels matching rows.
5. Explore results through time-series and diagnosis-code charts.

Quick start

# Local development
uv sync
uv run marimo run filter_engine.py

# Docker
docker build -t opensyndrome-databrowser .
docker run -p 7860:7860 opensyndrome-databrowser

Then open http://localhost:7860 in your browser.

Column mapping format

profiles:
  - name: my_dataset
    # value_encodings:  # optional — map OSD canonical values to dataset-specific ones
    #   sex:
    #     male: "M"
    #     female: "F"
    columns:
      my_diagnosis_column:
        concept: diagnosis
        dtype: string
      # my_age_column:
      #   concept: demographic_criteria
      #   attribute: age
      #   dtype: integer
