Hi Geert,
Thank you. Yes, that's what I have for now. But I was wondering that
maybe, using regex() on IRIs was not the best way to approach this.
For the record, this is what I have so far:
sem:sparql(
'SELECT DISTINCT ?s WHERE {
?s ?o ?p .
FILTER( regex(?s, ?re) )
FILTER( ! isBlank(?s) )
}',
map:entry('re', '.*[/#]?[^#/]*' || $input || '[^#/]*$'))
Regards,
