New SPARQL-Queries for presentations on conferences

[LibrErli]

For the upcoming German fully remote library conference #vBIB20 the metadata about all presentations are stored in Wikidata: Query

The scholia page on the event (https://tools.wmflabs.org/scholia/event/Q94495218) doesn't recognize any of them. Would be a good idea to add a list of presentations on an event page?

SELECT ?vBIB20 ?vBIB20Label (GROUP_CONCAT(?author_label; separator=" ; ") AS ?autor) WHERE {
  SERVICE wikibase:label { bd:serviceParam wikibase:language "[AUTO_LANGUAGE],en". }
  ?vBIB20 wdt:P361 wd:Q94495218.
  OPTIONAL { ?vBIB20 wdt:P50 ?author. ?author rdfs:label ?author_label. FILTER(LANG(?author_label)="en"). }
}
GROUP BY ?vBIB20 ?vBIB20Label

@LibrErli, is this issue still open? I note:
