Preserve alternate representations such as LaTeX while keeping presentation MathML available to browsers and assistive technology.
Core notation for MathML Semantics and Annotations
In mathml, the notation usually represents source notation, rendered output, semantic structure, code points, macros, and destination formats. The table below gives a compact starting set for mathml semantics and annotations; define any local variation before the first calculation.
| Concept | Notation | How to read it |
|---|---|---|
| MathML operator | \texttt{<mo>−</mo>} | semantic operator element |
| Aligned equations | \begin{aligned}a&=b+c\\d&=e\end{aligned} | multi-line alignment at relation signs |
| Accessible label | \text{“x squared plus one”} | plain-language reading when a text alternative is needed |
| Macro | \newcommand{\vect}[1]{\mathbf{#1}} | reusable semantic notation command |
Practical workflow
Start from \texttt{<mo>−</mo>} and write one sentence that says it means “semantic operator element.” List the objects and assumptions, evaluate a small example, and then move the verified source into the target document or codebase.
Decisions that must be explicit
- Keep editable source with the rendered result.
- Use semantic commands for mathml semantics and annotations rather than visual spacing tricks.
- Test the final destination, export path, and assistive-technology reading of the mathml semantics and annotations notation.
Failure checks
- Copying a rendered mathml semantics and annotations image when editable notation is required.
- Using a look-alike Unicode character with different semantics in mathml semantics and annotations.
- Defining mathml semantics and annotations macros that hide arguments or conflict with package commands.
Accessibility and portability
Keep the mathml semantics and annotations source selectable and editable. For an isolated character in mathml semantics and annotations, Unicode text may be sufficient; for structured expressions, preserve LaTeX, MathML, or a native equation object. When an image of mathml semantics and annotations is unavoidable, describe the operation, inputs, conditions, and conclusion rather than listing glyph names.
Verification checklist
- Copy and paste into plain text.
- Validate with a second renderer or browser.
- Inspect keyboard, zoom, PDF, and screen-reader behavior for the mathml semantics and annotations example.
- Confirm every symbol used in mathml semantics and annotations has one defined meaning in the local context.
- Reopen the exported file for MathML Semantics and Annotations and compare it with the editable source.
