i am using protege 4 to create an ontology

if the question was not clear, here is an example :

Superclass is (thing)

Subclasses are as follow (company) that has two data properties (company name) & (company abbreviation) (social network) (service)

an instance of company class is (macintosh) that has two data properties (macintosh) & (MAC)

an instance of social network class is (facebook)

an instance of service class is (adsence)

1# i want to say that mac has a logo and facebook has a logo so, logo has to be a class ? and if , how to r开发者_如何学编程elate an individual to a class by a relation ? is this possible to do ?

2# how to relate two individuals by a relation in protege ?

1

logo is a data property because logo itself has no properties and relations. It only has a value.

2

You will have to relate them while defining their classes first. Properties relate different classes. after that when you create an individual you will see a properties assertions panel. in this panel you can define relationships.

2

In Protégé 5 you can relate two individuals by going to the Class Expression editor of a selected individual and type:

<property> some {<individual>}

or

<property> value <individual>

For instance

hasPet value Tibbs

Where Tibbs is a specific individual.
