ONTOLOGY COMPONENTS

Instances: The general purposes of an ontology is to provide a means of classifying individuals. , even if those individuals are not explicitly part of the ontology.

Classes: Abstract objects.

Attributes: Properties.

Relations: ways in which classes can be related to one another.

“The patella is a part of the knee and is a bone organ.”

Ontology of Anatomy

The Foundational Model of Anatomy ontology

Protégé is an authoring and editing environment for ontologies.

Open questions and futur works

• FMA• Limited to anatomical structures• Genes expressions (phenotypes) • No used in practice (why?)

• MyCF• Focused on functions• Made to build physical 3D models • Take into account the finality of the models
