The following evaluation results have been generated by the RESTFul web service provided by OOPS! (OntOlogy Pitfall Scanner!). OOPS! is a software on development, and we will be happy to receive your feedbak. If you notice any issue in the evaluation, please contact us at oops@delicias.dia.fi.upm.es.
It is obvious that not all the pitfalls are equally important; their impact in the ontology will depend on multiple factors. For this reason, each pitfall has an importance level attached indicating how important it is. We have identified three levels:
Ontology elements (classes, object properties and datatype properties) are created isolated, with no relation to the rest of the ontology.
This pitfall affects to the following ontology elements:
This pitfall consists in creating an ontology element and failing to provide human readable annotations attached to it. Consequently, ontology elements lack annotation properties that label them (e.g. rdfs:label, lemon:LexicalEntry, skos:prefLabel or skos:altLabel) or that define them (e.g. rdfs:comment or dc:description). This pitfall is related to the guidelines provided in [5].
This pitfall affects to the following ontology elements:
Object and/or datatype properties without domain or range (or none of them) are included in the ontology.
This pitfall affects to the following ontology elements:
This pitfall appears when any relationship (except for those that are defined as symmetric properties using owl:SymmetricProperty) does not have an inverse relationship (owl:inverseOf) defined within the ontology.
This pitfall affects to the following ontology elements:
The contents of some annotation properties are swapped or misused. This pitfall might affect annotation properties related to natural language information (for example, annotations for naming such as rdfs:label or for providing descriptions such as rdfs:comment). Other types of annotation could also be affected as temporal, versioning information, among others.
This pitfall affects to the following ontology elements:
The ontology elements are not named following the same convention (for example CamelCase or use of delimiters as "-" or "_") . Some notions about naming conventions are provided in [2].
*This pitfall applies to the ontology in general instead of specific elements
An ontology element (a class, an object property or a datatype property) is used in its own definition. Some examples of this would be: (a) the definition of a class as the enumeration of several classes including itself; (b) the appearance of a class within its owl:equivalentClass or rdfs:subClassOf axioms; (c) the appearance of an object property in its rdfs:domain or range rdfs:range definitions; or (d) the appearance of a datatype property in its rdfs:domain definition.
This pitfall affects to the following ontology elements:
Two object properties or two datatype properties are defined as equivalent, using owl:equivalentProperty, even though they do not have the same semantics.
