XML

XML (eXtensible Markup Language) is a computer language used for transmitting data across the Internet, produced by W3C. Among MLN players, hackers in particular, the term "XML" is used to refer to the resource XML used to store MLN information, including Items and Badges. The current URL of this resource HTML is http://cache.lego.com/Upload/XMLCache/MLN/MLN_1033_20100211081940.xml.

Although it has been used for research purposes, the XML has achieved a level of notoriety for being used as a hacking tool.
