Aspect-oriented development has become one of the most intensively investigated themes in software development. In this paper, the method is proposed for reconfigurable modeling of aspect-oriented information system when <<Core>> and <<Aspect>> concerns may be represented separately and combined in different ways without changing their models or implementation. <<Aspect>> concerns are consistently represented during development process starting from <<Aspect>> use cases till crosscutting interfaces and templates for tailoring aspects for specific contexts. Examples from IT-Europe project are given where aspect-oriented concepts were used for modeling behavior of software agents performing self-management functionality of IT Knowledge Portal.
