Intermediate audience with knowledge of the software development cycle and familiarity with translation and verification of software.

Language packs (separately installable translated language modules for products) are implemented in two methods; development built or translation built. Most IBM development teams assign some of their personnel to the development of a language pack. It may be integrated into the base product or a supplemental part of the product install. These developers integrate the files into the project and deal with the translation team and the translation verification team.

In the translation team built model a separate team works with development to send language files to translation, create the language installation and coordinate testing. This reduces the load on the development team but requires a service organization to support the products; and can lead to delays if the translation team isn't large enough to accommodate multiple simultaneous product releases. The translation team needs detailed product architectural knowledge in order to produce a working language pack. Since both teams are working in interdependent code each team can introduce unintended and hard to trace defects into the product.

The Callback Language Pack Model (CLPM) is a new approach which divorces the process of product development and translation delivery from a particular development architecture. Translated files would be delivered on a separately installable media with a standardized language pack Installation program. This installer can install languages for one or more product at a time.

The function of the CLPM installer is limited to unpacking and moving files to a location accessible by the product and to notify the product the delivery has been made. The language installer can be a standardized and completely enabled installer that is uniform in look and feel and operation across an entire product suite. This presentation discusses the development and implementation of the callback language pack model.
