This document discusses a project to develop a web-based framework to conserve local knowledge of Javanese vernacular architecture. A team of lecturers and students from Soegijapranata Catholic University digitized existing research, conducted fieldwork to collect additional data, and created 3D models of buildings. They developed an e-learning platform and YouTube channel to promote understanding of Javanese cultural heritage. The project aims to preserve vanishing local knowledge and encourage modern interpretations of traditional design principles.
