摘要：Apache Wookie (incubating) has generated considerable interest within the context of Technology Enhanced Learning where it was developed, as well as in mobile applications. The origins of the system in providing services for IMS Learning Design are described, together with an introduction to the system's design and functionality. However, the areas where it has had success are distinct from the application area for which it was designed and developed. The implications of this for understanding user needs is analysed by using ideas drawn from sociology. The complexity of the relationship between the context of use and user needs, and the feedback loops between them is discussed, and the role of technological interventions as an element in a discourse is considered. It is proposed that this understanding of users needs, together with the experience of the development and use of Wookie, argues in favour of an interoperability strategy which focuses on relatively small sets of functional requirements, and avoidance where possible of specifications developed for particular application domains: an approach which may be characterised as piecemeal rather than Utopian.
