Service Level Agreements (SLAs) are a common way to formally specify such functional and non-functional conditions under which services are or are to be delivered. However, SLAs in practice are specified at the top-level interface between a service provider and a service customer only. Customers and providers can use top-level SLAs to monitor whether the actual service delivery complies with the agreed SLA terms. In case of SLA violations, penalties or compensations can be directly derived. The USDL Service Level Module allows modeling such information. The module is derived from our research as part of a multilevel SLA management platform." ; dcterms:modified "2011-04-20"^^xsd:date ; owl:versionInfo "0.1" . :Torsten_Leidig rdf:type foaf:Person ; foaf:name "Torsten Leidig"; foaf:title "Dr"; foaf:firstName "Torsten"; foaf:phone "+49 6227 7 52535"; foaf:lastName "Leidig" . :ServiceLevelProfile rdf:type rdfs:Class ; rdfs:label "service level profile" ; rdfs:comment "The container for the service level profile descriptions of a service.

Service levels are defined by the parties participating in service provisioning, delivery and consumption and express assertions that are claimed or expected to hold during these activities. Such assertions are always attributed to a single party, which is obligated to enforce the service level. From the viewpoint of the party defining the service level two cases are distinguished. Either the defining party obligates itself to ensure the service level, i.e., it claims that the assertion will hold, or the defining party expects the obligated party to ensure the service level, i.e., it requires the other party to enforce the assertion." ; rdfs:isDefinedBy . :GuaranteedState rdf:type rdfs:Class ; rdfs:subClassOf :ServiceLevel; rdfs:label "guaranteed state" ; rdfs:comment "A GuaranteedState is a particular service level that specifies a single state that must be maintained within the lifetime of any service instance, to which the respective service level profile applies." ; rdfs:isDefinedBy . :GuaranteedAction rdf:type rdfs:Class ; rdfs:subClassOf :ServiceLevel; rdfs:label "guaranteed state" ; rdfs:comment "A GuaranteedAction is a particular ServiceLevel that specifies a self-contained activity that must be performed, if and only if during the lifetime of any service instance to which the respective service level profile applies a specific precondition is fulfilled." ; rdfs:isDefinedBy . # Properties :hasServiceLevelProfile rdf:type owl:ObjectProperty ; rdfs:comment "Service level profile descriptions for a service" ; rdfs:domain :Service ; rdfs:isDefinedBy ; rdfs:label "has service level "@en ; rdfs:range :ServiceLevelProfile . :hasImplementationSpecification rdf:type owl:ObjectProperty ; rdfs:comment "Link to resource that contain either the complete formal definition/specification of this service level profile, or additional metadata that supplements the definitions in USDL" ; rdfs:domain :ServiceLevelProfile ; rdfs:isDefinedBy ; rdfs:label "has implementation specification"@en ; rdfs:range usdl-f:TechnicalMetadata . :hasServiceLevel rdf:type owl:ObjectProperty ; rdfs:comment "Service level descriptions for a service level profile" ; rdfs:domain :ServiceLevelProfile ; rdfs:isDefinedBy ; rdfs:label "has service level"@en ; rdfs:range :ServiceLevel . :obligatedParty rdf:type owl:ObjectProperty ; rdfs:comment "The party that is in charge to guarantee/enforce this service level" ; rdfs:domain :ServiceLevel ; rdfs:isDefinedBy ; rdfs:label "has service level"@en ; rdfs:range usdl-part:Role . :serviceLevelExpression rdf:type owl:ObjectProperty ; rdfs:comment "A ServiceLevelExpression specifies an expression that is evaluated in the context of a service level state or action.
