Semantic modeling for ancient architecture of digital heritage

In this paper, we introduce a semantic modeling project by implementing a southeast China vernacular urban modeling system. This system converts the basic modeling components of geometry units (e.g. point, line, triangle etc.) into the semantic components (e.g. street, block, patch, house etc.). To implement the urban modeling system semantically, an XML based description and DTD[31] based verifying technology has been used to control the process of urban generation in detail, and this DTD based verifying technology can avoid the disadvantage (such as hard to control etc.) of the grammar system and to ensure the coherent architecture styles of ancient vernacular houses. Because of the advantages (accurate modeling and rapid generating) of this semantic project system, it can be applied to the preserving of the digital heritage in southeast China vernacular architecture.
