objectsonto

Objectsonto is a term used in discussions of integrating object-oriented data models with formal ontologies. It refers to practices and tooling that treat software objects as ontological entities, enabling semantic annotation, interoperability, and reasoning over object properties and relationships. In this view, each concrete object class is linked to an ontology class, and instance data map to individuals in a knowledge base.

Etymology: The term blends “objects” and “ontology,” often written as ObjectsONTO or objectsonto.

Applications: Objectsonto supports data integration across systems, semantic web services, model-driven engineering, digital twins, and AI systems that require richer object semantics. It facilitates cross-domain queries and consistency checks by linking code-centric models to domain knowledge representations.

Architecture: Core components include ontology definitions (typically in OWL or RDFS), object schemas, and a mapping layer that aligns object attributes and methods with ontology properties. A reasoning engine can infer new relations, and query languages such as SPARQL can retrieve object-derived knowledge from the combined model.

Example: A software model includes a Customer object with attributes id, name, and email. In an objectsonto approach, there is an ontology class Customer with properties hasName and hasEmail; each Customer instance becomes a named individual linked to the ontology, enabling cross-domain queries with orders, invoices, or support tickets.

Limitations: Adoption is limited in practice; mapping between object models and ontologies can be complex and may incur performance costs. Versioning and alignment drift require governance and ongoing maintenance.
