ctp:hasPart and owl:propertyChainAxiom

[TizianaPasciuto]

When a Cultural Resource is part of a Thematic Path, they are linked by the Object Property ctp:hasPart. When Cultural Resources are sorted, there is a need to assign an index to each Resource. For this reason, the Object Property ctp:hasPart is equivalent to the combination of Object Properties ctp:hasSlot and ctp:hasItem and in the CTP Ontology Core this was rendered with owl:propertyChainAxiom (ctp:hasSlot ctp:hasItem).

When I run queries that can involve ordered cultural objects, as result I only get cultural objects that are related to the thematic path with ctp:hasPart, while I would need to get others too.

Possible solutions:

• Write a construct in order to match ctp:hasSlot and ctp:hasItem with ctp:hasPart;
• Insert in the sparql query the union of these two needs;
• indicate at the user in the ontology guidelines to bind cultural objects and thematic paths with both ctp:hasPart and with ctp:hasSlot and ctp:hasItem.

Possible solution - 2nd Where required, enter

WHERE{  
 {
    ?ThematicPath ctp:hasPart ?CulturalResource.
  }
  UNION
  {
    ?ThematicPath ctp:hasSlot ?OrderedListSlot.
    ?OrderedListSlot ctp:hasItem ?CulturalResource.
  }    
  }  ```

This issue has been resolved: the second solution proposed has been implemented, and it works. We reserve the right to evaluate the other two solutions later.
