Ontology for Maintenance Procedure Documentation (OMPD) Static Procedure Ontology

Title: Ontology for Maintenance Procedure Documentation (OMPD) Static Procedure Ontology

The following evaluation results have been generated by the RESTFul web service provided by OOPS! (OntOlogy Pitfall Scanner!).

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:

Critical: It is crucial to correct the pitfall. Otherwise, it could affect the ontology consistency, reasoning, applicability, etc.
Important: Though not critical for ontology function, it is important to correct this type of pitfall.
Minor: It is not really a problem, but by correcting it we will make the ontology nicer.

Evaluation results

P04. Creating unconnected ontology elements2 cases detected. Minor

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:

P08. Missing annotations140 cases detected. Minor

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:

P11. Missing domain or range in properties87 cases detected. Important

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:

P12. Equivalent properties not explicitly declared1 case detected. Important

The ontology lacks information about equivalent properties (owl:equivalentProperty) in the cases of duplicated relationships and/or attributes.

This pitfall affects to the following ontology elements:

P13. Inverse relationships not explicitly declared3 cases detected. Minor

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:

P24. Using recursive definitions1 case detected. Important

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:

"http://spec.equonto.org/ontology/maintenance-procedure/static-procedure-ontology#MaintenanceTask"^^xsd:anyURI

P30. Equivalent classes not explicitly declared2 cases detected. Important

This pitfall consists in missing the definition of equivalent classes (owl:equivalentClass) in case of duplicated concepts. When an ontology reuses terms from other ontologies, classes that have the same meaning should be defined as equivalent in order to benefit the interoperability between both ontologies.

This pitfall affects to the following ontology elements:

"http://rds.posccaesar.org/ontology/lis14/rdl/Role"^^xsd:anyURI , "http://rds.posccaesar.org/ontology/lis14/rdl/Function"^^xsd:anyURI

"http://rds.posccaesar.org/ontology/lis14/rdl/Organization"^^xsd:anyURI , "http://rds.posccaesar.org/ontology/lis14/rdl/System"^^xsd:anyURI

P34. Untyped class5 cases detected. Important

An ontology element is used as a class without having been explicitly declared as such using the primitives owl:Class or rdfs:Class. This pitfall is related with the common problems listed in [8].

This pitfall affects to the following ontology elements:
