Firstly, we discuss the necessity of a high level UIS conception and its influence on the final UIS quality. Secondly, we focus on the priority of computer data sources against the user interfaces, driven by a sound identification of natural user data sources which guarantees data quality in the sense of information uniqueness and actuality. The subject is strictly related to the correct definition of the main data collections by viewing their owners not only as clients of these resources but also responsible for their quality. Finally, a UIS prototype is shortly presented, which has been developed based on that conception.enText/Conference Paper1617-5468
