Adaptive hypermedia system stores information about particular user and according to this information, it adapts its output in accord to this user information. This paper focuses on general reusability of user data in adaptive hypermedia system which are used as an input of the adaptation process. This proposal is based on the mapping language, which maps user parameters (atomic parts of user information in adaptive hypermedia system) between the systems. The essential point of this proposal is, that the proposed integration is done by the external way (by definition of the mapping and external data pump), thus any changes in existing adaptive hypermedia systems are not necessary.
