Each language has its unique approach to defining constraints and validating graph data. In this work, we provide formal, concise definitions of the core components of each of these schema languages. We employ a uniform framework to facilitate a comprehensive comparison between the languages and identify a common set of functionalities, shedding light on both overlapping and distinctive features of the three languages.\r\n"}],"user_id":"114410","keyword":["RDF","property graphs","graph databases","schema languages","graph data validation"],"citation":{"chicago":"Ahmetaj, Shqiponja, Iovka Boneva, Jan Hidders, Katja Hose, Maxime Jakubowski, Jose Emilio Labra Gayo, Wim Martens, et al. “Common Foundations for SHACL, ShEx, and PG-Schema,” 2025.","apa":"Ahmetaj, S., Boneva, I., Hidders, J., Hose, K., Jakubowski, M., Labra Gayo, J.
