| The conceptual model of the Issue Procedure Ontology can be seen below, where their classes and properties are presented by means of a UML class diagram.
For better understanding, the ontology can be divided into four modules:
IssueEntity
Classes: IssueEntity, Asset, Image, skos:Concept.
Properties: directCategoryOf, hasDirectCategory, categoryOf, hasCategory, hasMaker, makerOf, hasAsset, assetOf, hasDepiction, depictionOf, title, description.
Persons and Organizations
Classes: Party, Person e Organization
Properties: hasMember, memberOf, name.
Problems and Symptoms
Classes: Symptom, Issue.
Properties: directlyCauses, directlyCausedBy, causes, causedBy, dependenceOf, dependsOn, directDependenceOf, directlyDependsOn, canDirectlyCause, canBeDirectlyCausedBy, canCause, canBeCausedBy, canBeDependenceOf, canDependOn, canBeDirectDependenceOf, canDirectlyDependOn, indicatedBy, indicates, hasCausativeAsset, causativeAssetOf, hasHostAsset, hostAssetOf.
Problems and Solutions
Classes: Action, Task, CompoundAction, Procedure, Activity, Step, Transition, BooleanExpression.
Properties: solves, solvedBy, hasFirstStep, hasStep, activates, hasSource, hasTarget, hasIncoming, hasOutcoming, hasGuardCondition, hasPostCondition, hasPreCondition, goal.
Classifying a IssueEntity
There are two ways of classifying a IssueEntity:
1 - A non-intrinsic classification, ie, a classification aiming a simple grouping of IssueEntities, where the IPO ontology provides ipo use of the property "ipo:hasCategory" linking to "skos:Concept", enabling the creation of schemes of categories and subcategories.
2 - A classification that is intrinsic to a IssueEntity, so that classification implies the creation of subclasses of IssueEntity with specific restrictions. For example, the "Hard Disk Problem" class being defined by a specific restriction that is being linked to at least one of the symptoms "Error Reading File" or "Error Writing File" (instances of Symptom class). Thus, resources can be classified based on the description of their symptoms, as an instance of the new class of "Hard Disk Problem" (HD).
