Simplified Maintenance Procedure


  1. Only new reference data items
  2. Max 50 reference data classes
  3. Simplified use of 15926-2

Details

1. Only new reference data classes

A new reference data item is an RDF node set as a subject in a list of triples.

rdl:newItem	a			p2:ClassOfInanimatePhysicalObject;
  		rdl:hasDesignation	"NEW ITEM"@en^^xsd:string

With new reference data items it is forbidden to add predicates to existing subjects in the RDL and it is forbidden to use 15926-2 to add a classification or a specialization to an existing item in the RDL.

# adding a new entity type to an existing RDL item is forbidden
rdl:RDS327239		a			p2:ClassOfArrangedIndividual;

# adding a new superclass to an exisitng RDL item is forbidden
rdl:newSpecialization  	a       		p2:Specialization ;
        		p2:hasSubclass    	rdl:RDS327239 ;
        		p2:hasSuperclass  	rdl:newItem ;

# adding a new classifier to an exisitng RDL item is forbidden
rdl:newClassification  	a       		p2:Classification ;
        		p2:hasClassified    	rdl:RDS327239 ;
        		p2:hasClassifier  	rdl:newItem ;

New reference data is allowed to be in the hasSubclass position in any specialization relationship or in the hasClassified position of any classification relationship. New reference data is also allowed to be in the hasSuperclass position or the hasClassifier position when the opposing position is filled with another new reference data item.

# making a new item a subclass of an existing item is allowed and recommended
rdl:newSpecialization  	a       		p2:Specialization ;
        		p2:hasSubclass   	rdl:newItem  ;
        		p2:hasSuperclass  	rdl:RDS327239 ;

# making a new item the superclass of another new item is allowed and recommended
rdl:newSpecialization  	a       		p2:Specialization ;
        		p2:hasSubclass  	rdl:anotherNewItem  ;
        		p2:hasSuperclass  	rdl:newItem ;
