WIRIS editor, when editing a LaTeX formula, adds the LaTeX part inside a semantics: <math xmlns="http://www.w3.org/1998/Math/MathML"> <semantics> <mrow> <mfrac> <mi>x</mi> <mn>4</mn> </mfrac> </mrow> <annotation encoding="LaTeX">\frac{x}4</annotation> </semantics> </math> All WIRIS editor services works internally with MathML. Then, why is worth storing the LaTeX? We use LaTeX as an input method for advanced authoring. We convert the LaTeX to MathML and we store the authors original version, which is what he will see when editing the formula again. Dani MathType embeds its rendering format ("MTEF") inside of <annotation encoding='MathType-MTEF'> .... </semantics> Neil Soiffer Senior Scientist Design Science, Inc. www.dessci.com ~ Makers of MathType, MathFlow, MathPlayer, MathDaisy, Equation Editor ~ On Mon, Dec 3, 2012 at 8:02 AM, Frédéric WANG <fred.wang@free.fr> wrote: Dear all, I've been looking at the usage of the <semantics> by various software tools generating MathML code. The most typical examples are LaTeX to MathML converters that embed the LaTeX code inside an <annotation> or Computer Algebra Systems adding content MathML inside an <annotation-xml>. The information can be shared between applications during file transfer or copy & paste operations. I started to write a survey here: https://github.com/mathjax/MathJax/wiki/Usage-of-the-semantics-element I'm wondering if some of you could provide details about how your MathML programs use <semantics> to provide information and whether you expect this information to be used by other applications.
