Abstract
This study analyses the spatial arrangement of a knowledge graph documenting conservation-restoration activities of cultural heritage, presented in the case of the monastery of San Millán de la Cogolla (Spain). The graph consists of three groups of nodes, concerning: (1) the physical reality, (2) conducted actions of conservation-restoration and (3) documentary archive. The goal is to explore how tailored spatial layouts can reveal beneficial links for decision-making, and how the analysis of the established paths helps to verify which relevant questions can be managed by the graph. The methodology involves comparing an initial network representation with a radial layout, assessing their complementarity and respective advantages. A novel contribution is that the visual inspection is extended by means of the adjacency matrix, which allows counting all possible paths of any length between nodes, and thus permitting more in-depth analyses about the number of indirect relationships and their meanings. The study highlights the benefits of combining different spatial layouts and computational analyses, integrating the multifaceted nature of graphs (communicative, semantical, and mathematical).
