MDDL Toolkit Purpose

• To aid financial institutions in creating and
  processing MDDL documents
• Demonstrate the use of shorthand and inheritance
• Show integration of MDDL and web services
• Future demo additional MDDL features
• e.g. Template-based validation

3
MDDL Toolkit Background

• First discussed at April, 2003 quarterly meeting
• By mid-year, Foliage agreed to take on toolkit
  development to aid FISD membership in rolling out
  MDDL
• Initial development began in July, 2003
• First release scheduled for January, 2004

4
Toolkit Features

• Demonstrates the use of Shorthand and Inheritance
  in MDDL documents
• Two-way demonstration (introduce and remove
  shorthand and inheritance)
• Uses XSLT to perform transformations
• Open standard, XML-based
• Same transformation logic usable by both Java and
  C (Both included in demo)
• Includes web-services demonstration code to
  easily show before-and-after documents

5
MDDL Shorthand

• Begin with something like
• ltlastgt
• ltmdDecimalgt15lt/mdDecimalgt
• lt/lastgt
• Wind up with
• ltlastgt15lt/lastgt

6
MDDL Inheritance

• Begin with something like
• ltaskgt
• ltopengt
• ltcurrencygtUSDlt/currencygt
• ltmdDecimalgt15lt/mdDecimalgt
• lt/opengt
• ltclosegt
• ltcurrencygtUSDlt/currencygt
• ltmdDecimalgt16lt/mdDecimalgt
• lt/closegt
• lt/askgt

7
MDDL Inheritance (contd)

• Wind up with
• ltaskgt
• ltcurrencygtUSDlt/Currencygt
• ltOpengt
• ltMDdecimalgt15lt/MDdecimalgt
• lt/Opengt
• ltClosegt
• ltMDdecimalgt16lt/MDdecimalgt
• lt/Closegt
• lt/Askgt

8
Shorthand Plus Inheritance

• You wind up with
• ltAskgt
• ltCurrencygtUSDlt/Currencygt
• ltOpengt15lt/Opengt
• ltClosegt16lt/Closegt
• lt/Askgt

9
XSLT and MDDL

• XSLT used for initial demo
• Good for a demonstration and for learning
• Demonstrates an open-standard method of
  transforming MDDL documents
• For full production systems, Java, C, C, etc.
  are probably more appropriate
• e.g. Cant store variables in XSLT
• Very difficult to track progress
• One advantage of XSLT can be offloaded to
  dedicated hardware

10
Future of MDDL Toolkit

• Potential additions include
• Adding template-based validation
• Based on business context of document
• Providing alternative language demonstrations
• Java, C, C, etc.
• Additional Web Services demonstrations in both C
  and Java
