.MML File Extension

File created using the Adobe Maker Markup Language (MML); used by Adobe FrameMaker, a program used to produce and publish large structured documents; contains formatting instructions for page layout, graphics, text, and other page properties.

MML files may be imported into an existing FrameMaker document, or they may be used to generate a new page layout. They are stored in an ASCII text format.

An MML file is an XML document that includes one or more mathematical formulas written using the Mathematical Markup Language (MathML). MML files are used to integrate mathematical formulas into .HTML webpages. You can recognize MML files by the <math xmlns="http://www.w3.org/1998/Math/MathML"> element.

You can open an MML file in Microsoft Visual Studio Code, GitHub Atom, or any other text or source code editor. Source code editors include helpful tools, such as syntax highlighting, that make viewing and editing MML files easier.

You can also open an MML file and edit the formula it contains in OpenOffice Math, LibreOffice Math, and Wolfram Research Mathematica.
