When professionals are given the task of analyzing a domain, it is likely that it is not the first time this task has been done. Rather than build upon what is already done they will often redo the work. The key problem that sustains this repetition of effort is the lack of a standard and centralized way to communicate and share the knowledge that results from the analysis. Software architecture for reuse and sharing of analysis knowledge is described, which incorporates a number of Internet technologies. The architecture is based around a visual modelling scheme and can be configured to adapt to the requirements of different organisational requirements.
