Questions about Lifecycle information in Facility Façade
Posted: Mon Mar 04, 2013 9:16 pm
The following questions are about sample data set published at http://15926.org/publications/HEED/HEED ... ntents.htm
1. In <!-- 5) - Installation of pump with serial number AC-5764M in function place P-101 --> we can see declaration of
<!-- Declaration of function place P-101 -->
<dm:PhysicalObject rdf:ID="C71439310-79bd-11e2-b92a-0800200c9a66">
<rdf:type rdf:resource="&dm;WholeLifeIndividual"/>
<rdf:type rdf:resource="&dm;ActualIndividual"/>
<rdf:type rdf:resource="&owl;Class"/>
</dm:PhysicalObject>
According to the Part 2 model, functional places where real pumps are installed and changed are FunctionalPhysicalObject, with " functional, rather than material, continuity as its basis for identity".
In what sense it is an instance of owl:Class? Individual should be an owl:Thing.
2. We can see an instance of p7tpl:BeginningOfIndividual template where functional place (not its temporal part) is stated to have some valStartTime value. In what sense functional object has a start time, what are the rules to determine a value for it?
3. <!-- Declaration of pump with Serial Number AC-5764M --> also defines it as owl:Class.
4. There is a mistake in the comment:
<p7tpl:valIdentifier rdf:datatype="&xsd;string">S/N AC-5764M</p7tpl:valIdentifier> <!-- Class of Stream CO_StreamSegm 123-34 -->
