What is the Issue?

• You heard a lot of transfer problems in many
  presentation today
• I can hear these problems much more often then
  you from Uta Seewald-Heeg
• Uta Seewald-Heegs solution
• Ask Georg

We have a powerful tool

• In 1983 I learned about Smalltalk
• What is the core about Smalltalk?
• Modeling instead of Programming

7
Modeling instead of Programming

• Who is Responsible?
• Oriented to Concepts of the Application Domain
• Concepts are mapped directly into Software

What is this?

• Wooden body in the form of a cylinder with
  approx. 20 cm (8 inch) height and 6 mm (1/4
  inch) in diameter.
• In the center of the cylinder are a drilling of 1
  mm and this are filled with pressed graphite.
• At end end the cylinder is conically tapered.
• The graphite can be transferred to other bodies
  by rubbing.

12
What is this?

• Plastic tube in the form of a cylinder with
  approx. 20 cm (8 inch) height and 6 mm (1/4 inch)
  in diameter.
• Inside is another plastic tube with 2 mm (1/12
  inch) in diameter and at the top there is a metal
  ball.
• The inner tube is filled with a viscous liquid.
• The liquid can be transferred to other media with
  the help of the ball.

Objects and Data

• Objects care about the services they provide
• Data is encapsulated inside and not a property
  visible from the outside
• Does this mean that todays topic is irrelevant?

16
Transfer Problems

• Syntactic file format does not match
• TSV (Excel) vs. XML vs. Text File
• File structure does not match
• Excel columns do not match
• DTD is different
• TML is different
• File contents does not match
• Import allows only language tuples
• Import does not allow duplicates

17
SSS-TTT Three Tier Transfer

• Syntactic tier maps keys to value
• Keys can be columns number, column headers or XML
  entity labels
• Structural tier maps logical attributes to to
  (multiple) keyed values
• Semantic tier maps logical attribute values
  (strings) to meaningful objects

18
Predefined Classes in Smalltalk

• For the syntactic tier
• XML Parser/Generator
• CSV Reader/Writer
• COM Connect
• .NET Connect
• As
• Everything in source
• Everything subclassable
• Everything changeable
• Adapt whenever needed

19
Structural and Semantic Tiers

• Can be very easily programmed
• Provided linguistic theory is available
• I did not study it
• I am sure you who have this

20
Immediate Feedback

• Agile Programming
• Make it work half way
• Try it out
• Make it work a little bit more
• Try it out
• Make it work
• Make it right
• Refactoring I
• Make it fast (if needed)
• Refactoring II

21
Objects and Database

• Databases are about relational Algebra
• Finite sets and their cross products
• Must always be interpreted (what is 061705 vs.
  611705 vs. 06366 vs. 6366?)
• Objects are about services they provide
• Objects can easily represent any linguistic
  theory
• Only Smalltalk provide full object features

22
Smalltalk Products

• Cincom Smalltalk
• Client and server platform
• GemStone
• Up to 1.099.511.627.775 objects
• Multi user
• Transactions
• High speed
• Persistence

23
Microsoft Glossaries

• http//www.lai.com/microsft.html
• ftp//ftp.microsoft.com/developr/msdn/newup/glossa
  ry
• 24 Languages
• 5.8GB in .csv Files
• Many too big to open them in Excel

24
Importing Microsoft Glossaries

• Problems
• Different number of columns
• Table headers sometimes missing
• Filename convention does vary
• Some language codes in 3, others in 2 characters
• Language codes for very uncommon languages

25
Problems and Solutions
26
After Reading

• You have a collection of objects
• Describe the contents of the files
• Can be sorted, filtered, matched,
• Can be exported to any desired format
• Can be used in VisualWorks tools
• L10N
• WebTCM

27
L10n localizes Applications
28
WebTCM localizes HTML-Pages

• Independence of language and culture
• Culture as personalization
• Every culture in every language

L10N Terminology Structure

• Key
• Translation
• Catalog
• Language Specification (de_DE)
• Version (Translator, Date)

31
TMX Export for L10N

• Problem
• Storing catalog, key and version

• Solution
• Storing this into property tags

32
TBX Export for L10N

• Problem
• Storing catalog, key and version

• Solution
• Storing key in ID-Tag
• Storing catalog name in Descrip-Tag

33
Conclusion

• Cincom Smalltalk and GemStone serves as an ideal
  tool
• Create ad-hoc transformations
• Create and modify Language Software
• Try out new ideas
• Observe during execution in nice GUI
• Modeling instead of Programming
• Every Software entity is understandable
