Schema

A W3C schema describing FreeMind XML file format can be found in the Git:

• freemind.xsd in Git, sourceforge.net

The schema was also copied to revision histories in the wiki, starting with FreeMind 0.8.0:

• Freemind.xsd

Extensions in version 0.9.0

Wiki documentation missing; however, the above linked freemind.xsd documents the file format as of FreeMind 1.0.1.

XML declaration

FreeMind writes no XML declaration.

FreeMind ignores, upon reading a mind map, any XML declaration that can be present in a mind map file created by another program[verify].

An example declaration: <?xml version="1.0" encoding="UTF-8"?>

• XMLElementAdapter.java in Git, sourceforge.net -- here is where most FreeMind-specific XML parsing upon reading and the corresponding creation of FreeMind Java objects is implemented, and changes in the mind map format should be usually(?) visible here
• XMLElement.java in Git, sourceforge.net -- the generic parsing tool from NanoXML 2 Lite, from which XMLElementAdapter.java inherits; this file should rarely see any changes
• NodeAdapter.java in Git, sourceforge.net -- saving is implemented here, but also in other classes that use XMLElement
