Intruder RDF properties and resources in triplestore

[eliarizzetto]

There seem to be three "intruder" properties in OC Meta graph (accessed in 16 September 2024). These properties are not included in any of the RDF vocabularies that are used by the OpenCitations Data Model, nor they are part of the ones used under the hood by Virtuoso.
The properties in question are the following

"#„Okocim"
"#Ohridski"
"#Davila" 

These intruder properties are apparently linked to intruder resources. For example, the query

SELECT ?s ?o {
	?s <#Davila> ?o .
}

returns the following result:

s	o

#Carol	Central Military Emergency University Hospital Bucharest Romania
