Introduction

MarieXML protocol uses an homemade xml format. This protocol intend to benefit from the XML properties to ease debugging and data analysis (lots of existing tools, standards, increased readability, etc.). The price to pay is to have bigger data footprints and increased serialization/deserialization delay than with a more "lightweight" approach.

XML HEADER	MARIE START HEADER	Datatype start header	fields	Datatype stop header	TIMESTAMP START HEADER	TIMESTAMP SEC START HEADER	sec	TIMESTAMP SEC STOP HEADER	TIMESTAMP USEC START HEADER	usec	TIMESTAMP USEC STOP HEADER	TIMESTAMP STOP HEADER	MARIE STOP HEADER

XML HEADER = "<?xml version="1.0"?>"
MARIE START HEADER = "<MARIE>"
MARIE STOP HEADER = "</MARIE>"

TIMESTAMP STOP HEADER = "</TIMESTAMP>"
TIMESTAMP SEC START HEADER = "<SEC>"
TIMESTAMP SEC STOP HEADER = "</SEC>"
TIMESTAMP USEC START HEADER = "<USEC>"
