GRAPHIA aims at developing innovative tooling for Social Science and Humanities researchers. One of these innovations is the creation of the GRAPHIA SSH Knowledge Graph, which should provide a unique entry point for researchers to retrieve datasets from multiple domains and sources of information. Creating such a global Knowledge Graph requires designing and adopting a common data model to align the different data sources together. This document describes the development of this common data model, the GRAPHIA Ontology. In the first section, we highlight the technical choices that drive this work, i.e. the technical architecture, described in Deliverable D2.2 and a state of the art on ontology development methodology and existing interoperability frameworks. The second section describes the scope and conceptual design of the GRAPHIA Ontology based on the choice made from the state-of-the-art analysis. The third section describes our methodology to develop the GRAPHIA Ontology, i.e. requirement collection, testing methods, publication and governance of the ontology. The fourth and final section provides an overview of the results of the development work, including an analysis of the initial data sources to be interconnected and of the potential additional candidate sources.
