There are a number of repositories for shared linguistic resources, such as names, digits, symbols and punctuation. These resources are named according to target language group, or after the language from which the resource is mainly taken.
Documentation on how to set up and use shared resources can be found here.
There is also giella-core, which contains shared build instructions and utilities for all languages.
Finally there is a section listing all template repositories. These are used partly as a starting point for new repositories, partly to update all existing repositories with new features or general improvements.
