Instance-based semantic graph of a quality specification of an anatomical entity. An instance-based semantic graph documenting the quality of a particular thorax surface, stored in a named graph instance of the ontology class ‘anatomical surface texture named graph’. The graph relates the instance of an anatomical surface with an instance of a subclass of the class ‘texture’ of PATO together with the class affiliation of the latter. For reasons of clarity, resources are not represented with their URIs but with labels.
