# Medicine SIOP API Guide without DBMS

## Principle
Use files as resources: JSON-LD for ontology, CSV for operational snapshots, JSON for events, and markdown/text for SOP knowledge.

## Static endpoints
- `/data/pilot_medicine_ontology.jsonld`
- `/data/pilot_medicine_ontology.ttl`
- `/data/sample_inventory.csv`
- `/data/sample_events.json`

## Data loader concept
1. Place source files in `/data`.
2. Map each column to ontology classes and properties.
3. Generate JSON-LD entities for products, batches, warehouses, companies and events.
4. Serve files directly or through a lightweight Node/Python function.
5. Feed the same files into a vector index later for RAG.

## Lightweight API example
```js
import express from 'express';
import fs from 'node:fs/promises';
const app = express();
app.get('/api/ontology', async (_, res) => {
  const data = await fs.readFile('./data/pilot_medicine_ontology.jsonld','utf8');
  res.type('json').send(data);
});
app.listen(3000);
```
