Today‘s Topic

• Not only in the Seaside Mailing List:

• How to create multilingual Web Applications?

• Easily!

Localization Process (according to Microsoft)

Localization in the Context of

Globalization and Internationalization

• Globalization (G11N)

• Internationalization (I18N)

• Localization (L10N)

Internationalization

• The process of enabling a product at a

technical level for localization. Source: LISA [http://www.lisa.org/Glossary.108.0.html?tid=1]

• Engineering culture and language-neutral

software kernels that can be compiled

together with separate “locale packages”

usually contained in independent resource

files. [Gregory M. Shreve, Kent State University]

Internationalization

• Internationalization is a precursor to

localization and its purpose is both to lower

the effort and cost of localization and

translation and to increase the speed and

accuracy with which localization can be

accomplished. In an age where the

simultaneous release of multilingual

documentation, web pages or software is a

corporate objective, such strategies are

indispensable. [Gregory M. Shreve, Kent State University]

Localization

The process of modifying products or

services to account for differences in distinct

markets.

The process of adapting software for a

particular geographical region (locale).

Translation of the user interface, system

messages, and documentation is a large part

(but not all) of the localization process.

Software Localization

• Adaptation of software for a particular

geographical region

• Translation of the user interface

• Linguistic and cultural adaptation of

websites

I18N and L10N together comprise a

complete process that makes the

adaptation of a product line for a

different linguistic and cultural locale

cost-effective and successful.

•I18N is “stuff” you have to do once.

•L10N is “stuff” you have to do over

and over

The more stuff you push into I18N out

of L10N, the less complicated &

expensive the process (Schmitz, 2001)

• Interpretion of byte arrays as character sequences

• Legacy

– ANSII (0 to 127)

– ISO8859L15 (with €)

– DOS, OEM, CP850

– Windows, MSCP1252

• Unicode

– 0 to 16r10FFFF (1.114.111)

Smalltalk and Encoding

• Current VisualWorks and ObjectStudio

– Characters are characters

– Strings are sequences of characters

– Interfaces know their string encoding

• Windows functions: UTF16

• Files byte order marks and autodetection

• ODBC: UTF16

• Rule:

– Never handle encoding inside the application

With all these Tedious Tasks

• Tools are needed

– Internationalization tools

– Localization tools

– Translation tools
