The document discusses the roadmap for future versions of TAO. Key points include: 1) TAO is built on knowledge technologies from Generis and will benefit from Generis' roadmap. 2) Main focuses are addressing scalability issues, supporting advanced tests and results, improving security, and supporting new forms of testing and devices. 3) Methods to improve scalability include tools for benchmarking, optimizing code and workflows, experimenting with knowledge representation layers and databases. 4) Enhancing security involves improving authentication, controlling test delivery, managing item exposure and analyzing user behaviors. 5) Contributions to the roadmap are welcome and can be made through the TAO
