A Layered Approach to Translating Online Documentation 
Localizing a large online documentation system is a significant, expensive, and ongoing project. SAP AG has adapted a layered approach to translation to help manage an online help system in 12 languages. This approach is based on an analysis of online documentation categories, and it is implemented by an analysis of the target markets. Technologies such as hypertext linking and text embedding need to be carefully controlled in order for this approach to be successful.
