Ontomedia Examples - Common (Other)

Scope: The majority were created as extensions to the ontology as the need arose from the examples that were being created for testing. In most cases there is a much better ontology out there that should be mapped in and used instead.

The bestiary classes was created to provide a basic structure to classify species. While humans and a few animal types have been included the main focus of the classes is mythological and other fictional species. It was decided that classifying real species was best left to domain experts within that area.


Similarly the Zoology classes were created to form a very basic structure for describing non-fictional animals. Using an ontology created by biologists instead is really recommended.

Physical Item and Profession

And again, with the physical_item and profession classes - they provided a very, very basic structure and other, more appropriate ontologies should be used instead, as needed.

Expression Properties

The expression property classes deal with ratings with can be applied to the instance to provide additional information. The accuracy rating allows an instance to be marked as accurate or approximate. This is especially important with numerical information such as ages because often the exact figure is not known.

The other rating, abstractness, allows for the genericness of the concept described by the instance to be stated. In general, information marked as exprop:Generic exists, with the same meaning in more than one context and the default assumption can be that two objects marked as exprop:Generic with the same class can be considered to be of comparable type even if they are stated to exist in different contexts. In the same way, exprop:Specialised information can be carried over into any sub-contexts while information given a ontomedia:Specific rating only belongs to the context is exists within. The exprop:Detail and exprop:Nitpick ratings indicate the information is very specific and if required can be ignored depending on restrictions of time and processing.
