The advances of Virtual Reality techniques have aided Virtual Environments become more dynamic and more realistic. The need to turn such systems closer to user's reality has led to environments that both track users actions and are capable of adapting to the users' profile. This article presents an infrastructure for managing virtual reality components, that allows the generation of adaptive virtual environments in real time in accordance to the user's profile. Such components are stored in a DBMS with XML support, which could be reused in the construction of new worlds. Each object of the world can contain several levels of information that will be introduced to the user in agreement with his/her learning capacity and knowledge level. With this proposal, an adaptive virtual environment for the Web can be generated which will follow the user's cognitive evolution in a dynamic and personalized way.
