old data in RDS-DEV #20

Closed ncarboni closed 4 years ago

ncarboni commented 4 years ago

The data present in RDS-DEV comprises several old datasets with the old prefix that need to be cleaned. Easy to check with :

PREFIX rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#>
PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#>
PREFIX crm: <http://www.cidoc-crm.org/cidoc-crm/>

SELECT DISTINCT ?concept
WHERE {
    ?concept ?p ?o
    FILTER ( strstarts(str(?concept), "http://grp.swissartresearch.net") )
}
LIMIT 100

The reason for these data was the existence of some (testing) data found under the namedgraph http://www.bigdata.com/rdf#nullGraph

The instances in the namedgraph were "orphan" in the sense that the only information attached to it was the rdfs:label (which in some cases was erroneous as well). The namedgraph has been removed.

@ncarboni you are welcome to test.

@ymark from initial tests seems perfect ! will do further testing, but in the meanwhile I close
