 Rating  A single Rating representing an entity's reputation, refers to other ways of representing reputation, subclassof:Reputation and has one owner
 ReputationObject  A Reputation Object of an entity related to multiple criteria, subclassof:Reputation and has one owner
 ReputationValue  Contains the current value of the criterion along with its past values if they exist
 PossibleValues   A set of possible values that a criterion in a reputation object can have (literals or resources) which can be a static predefined set  or a general range
 Context  A reputation context that represents multiple criteria
 Criterion  A reputation criterion to be evaluated and saved in a reputation object
 QualityAttribute  A reputation criterion regarding quality measuers
 Algorithm  A methodological method, entry point, or an engine
 ComputationAlgorithm  The method used to compute or aggregate several reputation values (i.e. reputation function)
 CollectingAlgorithm  The engine or method used to collect the value of a reputation criterion

Examples
This section shows some usage applications of Reputation Object Ontology classes.

Use Case 1: A foaf:Agent reputation object
<foaf:Person rdf:about="#Alice"> 
  <foaf:openid rdf:resource=http://alice.org''/>
  <ro:hasReputation >
  <ro:ReputationObject rdf:ID=''AliceRO1''>   
    <ro:hasCriteria> 
    <ro:Criterion rdf:resource=''#Driving''>
      <ro:hasReputationValue ro:value=8/>
      <ro:collectedBy ro:CollectingAlgorithm=''#Rating''/>
    </ro:Criterion>          
    <ro:Criterion rdf:resource=''#SocialActivities''>
      <ro:hasReputationValue ro:value=''active''/>
      < ro:collectedBy > 
        <ro:CollectingAlgorithm rdf:resource=''www.ex.org/NoOfFriends''/>
      </ro:collectedBy>
    </ro:Criterion> 
  </ro:ReputationObject>   
</ro:hasReputation >
</foaf:Person>  

Use Case 2: An e-market seller's reputation object
<gr:Reseller rdf:reference="http://www.example.org/John#"> 
 <ro:hasReputation >
 <ro:ReputationObject rdf:ID=''SellerRO1''>   
 <ro:hasCriteria> 
  <ro:Criterion rdf:resource=''http://purl.org/goodrelations/v1/DeliveryMethod''>
   <ro:hasReputationValue>standard</ro:hasReputationValue>
   <ro:collectedBy ro:CollectingAlgorithm=''#WebPortal''/>
  </ro:Criterion>          
  <ro:Criterion> 
    <review:Review>
      <review:rating>8</review:rating>
    </review:Review>
  </ro:Criterion>
 </ro:ReputationObject>   
 </ro:hasReputation >
</gr:Reseller>
