XSL-FO

• Extensible Stylesheet Language (XSL)Version 1.0
• W3C Recommendation 15 October 2001
• http//www.w3.org/TR/2001/REC-xsl-20011015/
• Version 1 was developed by W3C from 1998 to 2001
• The objective of XSL is to specify a layout of
  XML documents on paged media.
• 56 formatting objects
• including 248 properties

MathML

• MathML is the XML-based language for mathematics
• In 1997, the W3C's Math Working Group finished
  the MathML 1.0 Specification (superceded in 2001
  by MathML 2.0 )

XSL Formatter

• XSL Formatter is a software program, developed by
  Antenna House, to format XSL-FO.
• One of the first commercial XSL-FO
  implementations.
• Released in 2001
• Has been enhanced continuously.
• Input data XML/XSL-FO Raster/Vector Graphics,
  SVG
• Output data PDF, Windows printer, Windows GUI,
• SVG (under development, the function is
  not available with V3.2)
• Operating System
• Windows2000/2003,XP, Linux, Solaris
• AIX, Mac OS X (from V3.2 or later)

MathML option for XSL Formatter V3.2

• Developed by Antenna House
• Renders MathML markup instance that is embedded
  within XSL-FO
• It will be released as an optional function for
  XSL Formatter V3.2 and/or later.
• Evaluation version is available from here
• http//www.antennahouse.com

What will MathML option do?

• High quality rendering of XML for STM
  (Scientific, Technical, Medical) publishing using
  XSL-FO MathML
• XSL-FO MathML will replace TeX in the future
• TeX is popular, but it is not XML

7
MathML both for Web and PDF

• XML to XHTML
• XML MathML ? XHTML MathML
• XML to PDF
• XML MathML ? XSL-FO MathML

8
MathML within XSL-FO

• How to specify MathML expression within XSL
  formatting object
• MathML is treated as a vector Image
• XSL-FO V1.0 specification only permits to embed
  foreign object via
• foinstream-foreign-object
• and
• foexternal-graphic.

9
foinstream-foreign-object

• DTD declaration is necessary to use entity
  reference in MathML.
• In case DTD is necessary
• ltfoinstream-foreign-objectgt
• lt!CDATAlt!DOCTYPE math PUBLIC "-//W3C//DTD
  MathML 2.0//EN" "http//www.w3.org/Math/DTD/mathml
  2/mathml2.dtd"gt
• ltmath xmlnshttp//www.w3.org/1998/Math/MathMLgt
• ... MathML including entity reference...
• lt/mathgt
• gt
• lt/foinstream-foreign-objectgt
• In case without DTD
• ltfoinstream-foreign-objectgt
• ltmath xmlnshttp//www.w3.org/1998/Math/MathMLgt
• ... MathML without entity reference...
• lt/mathgt
• lt/foinstream-foreign-objectgt

10
foexternal-graphic

• Specify URL of MathML file as the value of src
  property of foexternal-graphic object
• ltfoexternal-graphic
• src"url('MathML/rec-rambda2l.mml')"
• content-type"application/mathmlxml ...
  /gt

11
Inline and Block

• Inline object
• Block object

object is treated like a character
enclose foinstream-foreign-object within foblock
Example
Inline
...
Block
12
Interface

• MathML Renderer inherits following information
  from its environment
• font-size
• font-family
• font-weight
• font-style
• length of a 1px
• XSL-FO processor gets following information from
  MathML renderer
• position of base-line

13
MathML Support Level

• Conformance to MathML 2.0 Specification
• W3C MathML Test Suite result
• V3.2 Beta version
• Please refer to information on CD

Compatibility Issue

• Many tools are expected to be used throughout the
  world.
• MathML instances are generated by various tools,
  such as equation editors and/or converters.
• Compatibility between generator and renderer of
  MathML is very important
• Correct MathML generation by various tools is a
  presupposition of automatic MathML rendering.
