Definition: Ontology ABB is a Data Object that defines a set of representational primitives with which to model a domain of knowledge or discourse Source: Formal definiion of Tom Gruber Source reference: https://tomgruber.org/writing/definition-of-ontology Last modification: 2024-01-28 Identifier: http://data.europa.eu/dr8/OntologyDataObject LOST view: Semantic view EIRA concept: eira:ArchitectureBuildingBlock ABB name: eira:OntologyDataObject Example: The following implementation is an example on how this specific Architecture Building Block (ABB) can be instantiated as a Solution Building Block (SBB): Medical Dictionary for Regulatory Activities Terminology (MedDRA) - The university ontology includes classes, e.g., :Staff, :Students, :Department or :Course. These classes denote natural concepts that are shared or at least understood by users familiar with universities all over the world. Universities ontologies can be view in university portals.(http://bioportal.bioontology.org/ontologies/MEDDRA) Interoperability Saliency: The Ontology ABB is salient for semantic interoperability because it defined as a simplified, reusable and extensible data model that capture the fundamental characteristics of a data entity in a context-neutral and syntax-neutral fashion. Additional information: Ontology ABB is a Data Object aiming to be a formal description of knowledge, as a set of concepts, within a domain and the axioms connecting concepts and allowing for logic inferences. When speaking about an ontology, we do not refer only to the terminology (or T-Box) but also to all the “assertions” about the concepts and roles (the A-Box), i.e. all the individuals or instances of concepts and roles of the terminology and as important, the rules for logic inference: the semantics “part".
