Abstract
SIArch-Univaq is a knowledge-based instrument for the cataloging of historical architectural heritage, created to provide a powerful cognitive tool to all operators interested in studies and conservation. The principle characteristic of this architectural Information System is its notable capacity of in-depth analysis, going down to the identification of all the constructive components with simplicity of consultation, activated by one or more three-dimensional models deliberately created.
