# Interactive Menus
## Markup Language Introduction
For interactive menus the FOpen Interactive Markup language is used, a comepletely ad-hoc declarative solution. While the older consumer alternatives for HD physical media used technologies like Java (BD-J on Blu-ray) and Web-Based Technologies (HDi on HD DVD), they all come with different costs and disadvantages:

- BD-J uses a complex Java ME platform
- Web Technologies rapidly evolve, making web-based menus too dependent on web engines
