Maple supports MathML
2.0, an emerging communications standard sponsored by the World
Wide Web Consortium (W3C) for representing and interpreting mathematical
expressions, including their display in Web pages. MathML is an extension of
HTML.

Maple MathML support allows users to export Maple output expressions and
worksheets as MathML-enriched Web pages. Earlier versions of MathML deal only
with the display of mathematical expressions. MathML 2.0 represents both their
display and their meaning.

How to Export Maple Output as MathML

Export a worksheet as an HTML document for viewing in a Web browser.

1. Open the worksheet that you want to export.

2. From the File menu, select Export As. The
Export As dialog opens.

3. Select HTML as a file type.

4. Specify a path and folder for the file.

5. Enter a filename.

6. Click Export. The HTML Options dialog opens.

7. In the Image Subdirectory field, enter the
pathname for the directory where exported images are to be saved.

Images in an HTML document cannot be saved in the HTML file. Each image is
saved in its own GIF file. If the directory that you specified does not exist,
it
is created for you. All image directories are relative to the document. The
default directory is images, and it is located under the same directory that
was selected for the HTML document. For example, if the HTML document is saved
in /u/mydocs, the default image directory will be /u/mydocs/images. An Image
Subdirectory of "" causes the images to be saved in the same directory
as the HTML file.

8. To export the worksheet as an HTML document
with frames, select the Use Frames check box.

9. To export mathematical expressions as MathML
instead of GIF images, select the appropriate MathML check box.

10. Click OK.

Proper Display of Exported Worksheet

Your browser determines whether you can properly display the exported worksheet using MathML 2.0 with WebEQ, MathML 2.0, MathML 1.0, or GIFs for the formatted mathematical output.

- If you select MathML 2.0 with WebEQ, the exported worksheet displays properly
only if your browser supports WebEQ and revision 2.0 of the MathML standard
set by the World Wide Web Consortium (see http://www.w3c.org/Math/).
In version 2.0, mathematical expressions are represented in parallel MathML
encoding, where both explicit presentation markup and explicit content markup
are included for the representation of the expression.

- Similarly, if you select MathML 1.0, the exported worksheet displays properly
only if your browser supports this standard. In version 1.0, mathematical
expressions are represented in presentation-only MathML encoding.

- If your browser cannot display mathematical expressions as MathML version
2.0 or MathML version 1.0, you can export mathematical expressions as GIF
files instead of MathML.

If **WebEQ**
is not currently installed on your system, the MathML viewer is invoked over
the Internet. This can cause slight delays when opening the HTML file. To avoid
these delays, you can **install
the WebEQ MathML Viewer permanently on your machine.**

Individual Maple Expresssions

This produces a string containing the MathML representation of the Maple expression. To list the string in tab-indented layout, issue this command next:

Alternatively, you can right-click on the Maple output expression you wish to export. From the context-sensitive menu that pops up, select

You can copy the MathML string to the clipboard and then paste it into any other Maple worksheet. The pasted expression will be the Maple expression represented by the MathML string.
