“A great variety of Web sites displaying cultural aspects of landscapes exist today. Although built on different design patterns, all these Web sites have to cope with the typical problem of creating a concise but comprehensive representation of a variety of cultural resources within a framework of time and space. In this paper we discuss currently predominant but very different approaches, ranging from an historical GIS and a wiki with Google maps to illustrated HTML-documents and Flash-based visual narratives. We propose a model that identifies generic requirements for spatiotemporal cultural heritage Web sites. The model helps to understand how well different implementation environments suit various objectives. The model is applied to our own cultural landscape portal on the region around the Vecht, a small river which runs from the city of Utrecht to the north, at both sides fringed by a rich historical landscape.” (Leen Breure et al. – Museums and the Web 2008)
