# @context

The open standard reference for interpreting the markup contents.

```
string @context
```

## Overview

For JSON-LD, the `@context` for a reservation should always be `http://schema.org`, as in this example:

```xml
<script type="application/ld+json">{ "@context": "http://schema.org", "@type": "TrainReservation", "reservationId": "ASDF1234" /* more data goes here */ }}</script>
```

For Microdata, provide the URL as part of the `itemtype`, as in this example:

```xml
<section itemscope itemtype="http://schema.org/TrainReservation">
Your reservation
<span itemprop="reservationId">ASDF1234</span>
is confirmed!
/* more data goes here */
</section>
```
