Template: http://tpl.ottr.xyz/p/asset-maintenance/interface/0.2/WorkOrderForm

URI: http://tpl.ottr.xyz/p/asset-maintenance/interface/0.2/WorkOrderForm

Parameters

🛈 The parameters defined by the signature are listed here. Unfortunately parameter names are not informative; fixing it is a planned future feature. An optional parameter will accept the value ottr:none as an argument. A parameter which allows blanks will accept a blank node as argument value.

Pattern

stOTTR

🛈 stOTTR serialisation of the template without annotation instances.

<http://tpl.ottr.xyz/p/asset-maintenance/interface/0.2/WorkOrderForm>[
    owl:NamedIndividual ?id,
    xsd:date ?date,
    xsd:string ?descr,
    owl:NamedIndividual ?funcLoc,
    owl:Class ?failureFuncLoc,
    owl:Class ?code,
    owl:NamedIndividual ?failure
] :: {
    <http://tpl.ottr.xyz/p/asset-maintenance/fmea/0.2/RealizedFailureCategorization>(?failureFuncLoc, ?code, ?failure),
    wo-tmp:WorkOrder(?id, ?date, ?descr, ?funcLoc, ?failure)
} .

🛈 The pattern of the template is illustrated by expanding a generated instance. Below the generated instance is shown in different serialisations, and its expansion is presented in different formats.
