## Endpoints

Available for each locale (root `/`, `/fr/`, `/zh/`):

| Format | URL | Content-Type |
|--------|-----|-------------|
| JSON-LD | `https://blackcatinformatics.ca/index.jsonld` | `application/ld+json` |
| Turtle | `https://blackcatinformatics.ca/index.ttl` | `text/turtle` |
| N-Triples | `https://blackcatinformatics.ca/index.nt` | `application/n-triples` |
| VoID | `https://blackcatinformatics.ca/.well-known/void.ttl` | `text/turtle` |

Locale variants follow the same pattern: `https://blackcatinformatics.ca/fr/index.jsonld`, `https://blackcatinformatics.ca/zh/index.jsonld`, etc.

## Content negotiation

Requesting a locale root with an appropriate `Accept` header returns the matching format:

- `Accept: application/ld+json` → JSON-LD graph
- `Accept: text/turtle` → Turtle serialisation
- `Accept: application/n-triples` → N-Triples

HTML remains the default for unqualified requests.

## Schema

The JSON-LD graph uses Schema.org vocabulary and describes an `Organization` entity with services, knowledge areas, principals, publications, and patents.
