Appendix A. Advanced XServe Configuration

8.1 Configuring XServe

XServe is configured through a set of XML Configuration files. Each file defines how a data
packet from the mesh is parsed and converted into sensor data. It also describes which
processing module will handle the sensor data and how it will be processed.

XML Configuration files consist of 3 sections:

•

Field Definitions:

Field Definitions describe the structure of a mesh data packet and

define how to convert mesh data into sensor data. These definitions are responsible for

parsing the incoming mesh data.

•

Filter Definitions:

Filter Definitions construct logical statements which determine the

type of any incoming mesh data packets and are used to choose the appropriate XML

Field Definitions to parse the data packet.

•

DataSink Parameters:

Datasink Parameters describe which processing modules will

handle the sensor data, and pass data specific parameters into the processing module.

Below is a portion XML Configuration for a MTS300 data packet:

<?xml version="1.0" encoding="ISO-8859-1"?>
