Lokalise file formats

Mike's Notes

I discovered this list of file formats on the Lokalise website. The files store translation strings and are used by Lokalise for import and export.

I designed Pipi 9 to support any human language and writing system (script) in the future. This is done by separating string storage from the underlying code, data models, etc.

The Language Engine (lng) stores a standard set of strings. One engine per language/script). These engines then interact with the Factory Engine (fac) to build in one language/script.

• Each engine or object
• Each plug-in
• Each DDD module
• etc

Examples

That means there can be an English-in-Latin script version of the DevOps Engine (dvp), a Kurdish-in-Latin, a Kurdish-in-Hawar, and ;a Kurdish-in-Sorani, etc script version of the DevOps Engine (dvp), etc. The same goes for all plug-ins and SaaS apps; each can be available in many languages/scripts where needed.

Use

This will be very useful when I return to do more work on the Language Engine (lng).
