An ontology, named the Connective Ontology, was designed to record and classify references, borrowings, and similarities in arguments within religious polemical discourse. In line with best practices, terminology from two previous projects was adopted, the Hypermedia Dante Network (HDN) and Sharing Ancient Wisdoms (SAWS). These ontologies, as well as the Connective Ontology, were aligned with the widely recognized top-level ontologies in the humanities, CIDOC CRM and LRMoo. This alignment ensures broad compatibility with other Digital Humanities projects and facilitates interdisciplinary knowledge sharing.
To build the proof-of-concept knowledge base, intertextual connections were extracted from six text editions within the CMRE tradition. These connections were homogenized and refined, among others by assigning precise positions to intertextual connections, standardizing references to source works – which often vary between editions – and ensuring consistent recording of this information. The argumentation in the texts was paraphrased, summarized, and then, like the intertextual references, linked to specific text passages. Finally, the data were converted to the target Linked Data format. A preliminary corpus was published under the dataset OTRAone.
In addition to this technical work, the project explored broader questions of how knowledge about connections between texts can be shared and how interreligious connectivity can be studied. These issues were addressed through talks, papers, and an international workshop.
