In this context, this work presents Open-ArcH, a digital approach for architectural heritage representation that relies on the integration of HBIM methodology with a knowledge base developed by means of graph databases, with two major objectives: 1) it supports the formalization of the complex semantics that it is necessary for a full comprehension of the artefact, currently poorly managed by HBIM application, and 2) the openness and flexibility ensured by the graph database technology allow for its adoption in heritage investigation and conservation processes by the different actors involved, providing them with the capability of collaborating to the construction of the knowledge base of the artefact.
