SIRI XML schema

SIRI XML Document Structure

Siri XML document have a root Siri element that indicates the schema and version to which the document conforms.

A SIRI XML document is a computer file containing XML data that adheres to the SIRI schema. It must have a root Siri element that indicates the schema and version to which the document conforms. The document can then be validated against the schema to ensure correctness, meaning it is well-formed XML that conforms to the SIRI schema and satisfies key referential integrity constraints specified by the SIRI XML Schema

Here is an example

<Siri xmlns="http://www.siri.org.uk/siri" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.0" xsi:schemaLocation="http://www.siri.org.uk/siri ../../xsd/siri.xsd">

Structure of the xxxDelivery element

The xxxDelivery element consists of two sections:

1. Header

The header contains a mandatory ResponseTimestamp element

2. Payload

corresponds to the description of the object itself independently of any and other headers

Example

Here's an example of a ServiceDelivery element with a header and a payload

<Siri xmlns="http://www.siri.org.uk/siri" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.0" xsi:schemaLocation="http://www.siri.org.uk/siri ../../xsd/siri.xsd">
