Upgrading to the Symbolic String Model

Upgrades: Releases 7.0.x, 7.5.x.

Environments: Development environment only.

This topic is part of an upgrade process. See How to Perform the Upgrade.

Release 7.7 introduced a symbolic string model. It replaces the locale-based string model. In the locale-based string model, each UI text string in the Tools repository is part of a UI object definition, such as an applet. The translations of the text string are maintained as child objects in child locale records for each UI object. For commonly used text strings, this means there is a lot of redundancy between UI objects.

The new symbolic string model is object-oriented. A single symbolic string replaces the text string translations. For each language, a text string is defined and assigned to the symbolic string as an attribute. This simplifies multilingual management of text strings throughout the UI.

Some strings will not be converted to the symbolic string model during upgrade. Seed data, error messages, lists of values (LOVs), and non-translatable attributes (such as the text alignment property on a control) will continue to use locale-based strings.

You must execute a conversion utility (consoleapp) to convert and consolidate your custom locale-based strings to the new model. If you plan to install a language pack, it is recommended that you do so before you run the string conversion or consolidation process.

Procedures for converting or consolidating to the symbolic strings model are found in Using Siebel Tools.
