Prooviding users with homogeneous, tailored and non-redundant information is a very demanding task in today's computing environments - where such in formation is likely to be stored in several autonomous information repositories. Moreover, user requirements are likely to change over time - which necessittes that integration frameworks should be flexible enough to support diversity and dynamicity in these requirements. In this paper we describe a novel approach to supporting the paper we describe a novel approach to supporting the flexible integration of heterogeneous information resources - where diversity and dynamicity of user requirements are emphasised.
