Introduction

The PLM - Plant Life-cycle Model is a model of placeholders for information for each LIFECYCLE ACTIVITY. In fact it is the foundation for the entire life-cycle information.

So, in case you have Maintenance information, exported from some MMS - Maintenance Management System, you map it to templates and you know where to put it. It resembles a relational data base (ATTENTION: IT ISN'T ONE!), where you know where to store your data.

In ISO 15926-7/8 those data are mapped to Templates, that have, in the case of MMS information, PLM Nodes [93] and [94] (In-line Maintenance) or [95] and [96] (Shop Maintenance) in their 'signature'. Since each Asset item will, predictably, be maintained sometimes, these Nodes can be declared as soon as the Asset is registered at Node [76], or in case of In-line Maintenance, as soon as the Asset is installed (Node [84])..

The relations in the PLM have been mapped to Templates and are in the code.

The Turtle code for the PLM can be found here.

Example

Let's assume that the actual pump with Asset Number A573391 required shop maintenance, which started on December 15th, 2023, and has costed USD 1227.00.

Note that the data in this diagram are different from those below.

We take the code:

##### NODE 95 #####    
ex:95
	rdf:type lci:InanimatePhysicalObject, dm:ActualIndividual, rdl:R3 ; 
	rdfs:label "Node 95 - Temporal part of [labelOf ex:76] participating in [labelOf ex:96]" ;
	meta:hasLifeycleActivity  rdl:RDS2229991 ; # SHOP MAINTENANCE
	meta:valEffectiveDate "yyyy-mm-ddThh:mm:ss.sZ"^^xsd:dateTime .

##### NODE 96 #####    
ex:96
	rdf:type dm:Activity, dm:WholeLifeIndividual, dm:ActualIndividual, rdl:RDS2229991 ; 
	rdfs:label "Node 96 - Shop Maintenance Activity" ;

Instantiation

We can fill this with the data we have at hand.
Note that Node 95, although being a temporal part of Asset 76, acts like a whole-life individual for all Shop Maintenance information related to this maintenance ticket.
