Installing Plugins¶

OXFORDIA's extensibility model is a two-axis plugin system:

Data Plugins describe a kind of data — a domain-specific shape, schema, and vocabulary.
Statistic Plugins describe a kind of computation — mean, Kaplan–Meier, regression, and so on.

The two axes compose: a Mean Statistic Plugin can be used against any compatible field exposed by any Data Plugin. Adding a new disease's data model does not require touching any statistic; adding a new statistic does not require touching any data model.

Plugin installation¶

Plugins ship as standard installable packages. Install them on your node alongside the core oxfordia-pod package.

# Example: install the nemaline data plugin
sudo apt install oxfordia-plugin-data-nemaline

# Example: install the Kaplan-Meier statistic plugin
sudo apt install oxfordia-plugin-stat-kaplan-meier

# Restart the node to load new plugins
sudo systemctl restart oxfordia-pod

For Kubernetes deployments, add the plugin image references to your Helm values file:

plugins:
  data:
    - name: nemaline
      image: ghcr.io/oxfordia-project/plugin-data-nemaline:latest
  statistic:
    - name: kaplan-meier
      image: ghcr.io/oxfordia-project/plugin-stat-kaplan-meier:latest

Operational note¶

New statistic plugins must be installed on every node in the federation where they will be available. This is a known operational cost of the plugin model. Plugins ship as standard installable packages to minimize that cost, and the long-term roadmap includes a more general query layer that reduces the per-node install requirement.
