Small ontology around Pablo Picasso (entry point to the chapter)

The canonical treatise introduces conceptual modeling with a compact example ontology centred on the artist Pablo Picasso: classes (e.g. person, museum, artwork), data and object properties, and instance assertions illustrate naming, symbols, and how knowledge subjects connect. The same example reappears when discussing object properties (instance-of, exhibition location, authorship) and inverse assertions.

From here, continue to Semiotic triangle, Ontological concepts, and OntoGraphs for notation and visualization. [GuBe2021] provides foundational orientation; [AlHe2020] ties the example discipline to RDF/OWL practice.

The original page lists tuples such as (>NPS-Pablo_Picasso, ◊iof, ^natPerson), museum and artwork individuals, and links like ◊isPaintingOf and exhibition location. Inverse triples swap subject and object and use the inverse OP name. These patterns are the concrete counterpart to the abstract definitions on the canonical Example knowledge graph page.

When you grow such an example into a full KB, keep predicate and individual names aligned with the chapter so triple and rule editors stay readable.
