I'm trying to run a SPARQL query on sdmx-dimension:refPeriod in order to get the date. The triple that contains the date is in the format:
exp:obs0 sdmx-dimension:refPeriod exp:2020-08-03
so when I go to extract the date with:
SELECT ?date
WHERE {
? obs sdmx-dimension:refPeriod ?date
}
I get the IRI of the resource "date":
http://example.org/2020-02-24
Instead I would only like to get the date value.
Is there any way in SPARQL to do it? Or, after receiving the results of the query, do I have to go to parse the result in order to get only the date?
