This page contains several SPARQL-Queries to help debug the graph.
Missing Properties
No Resources
Returns all Items, that don't have any resource that they link to.
Note: Only searches through items that have a subclass, to avoid duplicates
No Subclass
Returns all Items, that don't have a property subclass.
No Dependencies
Returns all Items, that don't link any other items as dependency.
These items don't have a property depends on. This could mean, that they are a source or that they are orphaned.
Orphans
Returns all items, that don't link to any other items and are not linked to in return.
NOTE: Not sure if this works.
