1. A Formal Ontology: This is the rulebook. Built using standards like RDF, OWL, and SHACL, the ontology is an intentional, explicit contract of meaning. It defines the classes of things that matter (Customer, Contract, Product), their properties (hasName, hasValue), and the relationships between them (coversProduct, assignedTo). This is where you declare, unambiguously, that a Debitor in SAP is, in fact, the same as a Client in Salesforce.
ontology here is an information management ontology, mapping variables and their properties across applications ('domains' used above is a confusing term then). The mention of SAP here is a tell, in the sense of what type of scale of enterprise we're talking about.
