**3.2.1 Attributes of concepts**

In medical service ontology, the concepts of actors, events and states are especially important. Thus, we here describe the attributes of actor concepts, state concepts and event concepts in Figures 3, 4 and 5, respectively.

Fig. 3. Concepts and their attributes of actors (stakeholders).

In Figure 3, yellow rounded rectangles denote concepts, and pink rounded rectangles denote attributes. In general, pink rounded rectangles in diagrams on Semantic Editor denote properties.

The concept [actor] has three attribute ⟨sex⟩, ⟨name⟩ and ⟨birth date⟩. The sub classes [patient] and [medical staff] of [actor] have all attributes of [actor] and special attributes ⟨blood type⟩ and ⟨affiliation⟩, respectively. Though these concepts above have other attributes, we omit them since we do not use them in this paper.

The arrow "domain" from the attribute ⟨affiliation⟩ to [medical staff] denotes that the concept that has ⟨affiliation⟩ as an attribute is [medical staff], while the arrow "dom1" from the attribute ⟨sex⟩ to [actor] denotes that the concept having ⟨sex⟩ as an attribute is [actor] and that each actor has a single sex. On the other hand, the arrow "range" from the attribute ⟨blood type⟩ to the concept [blood type] denotes that the type of values of the attribute ⟨blood type⟩ is the concept [blood type]. On the other hand, the arrow "subClassOf" from the class [patient] to the concept [actor] denotes that [patient] is a sub class (a sub concept) of [actor].

The concept [state] in Figure 4 have five attributes ⟨subject (of a state)⟩, ⟨starting event⟩, ⟨terminating event⟩, ⟨starting time point⟩ and ⟨terminating time point⟩. ⟨starting event⟩ denotes a trigger of a state if the state has such a trigger, while ⟨terminating event⟩ denotes a trigger to stop a state. The arrow "dom01" from the attribute ⟨starting event⟩ to [state] denotes that [state] has ⟨starting event⟩ as an attribute and that each state has a single starting event or does not have any starting event.

The ontology has two types of properties: the first type is an attribute of a concept, and the second type is a relation between two concepts. An attribute is a property that a concept own as an important part or feature. For example, name is one of typical attributes of a
