How to specify a typed literal in the header?

[EmidioStani]

In the header of the spreadsheet if I specify:

dct:created "2018-07-09"^^xsd:date

the generated RDF becomes a literal surrounding the xsd:date, e.g:

dct:created "\"2018-07-09\"^^xsd:date";

or if I remove the double quotes:

dct:created 2018-07-09^^xsd:date

it becomes:

dct:created "2018-07-09^^xsd:date";

No no, you need to specify the datatype on the property header, not in the value cell. Like so:

This is the same syntax as documented at https://skos-play.sparna.fr/play/convert#datatypes

ok I got it, thanks.

What if I want specify a URI as Literal ?, for example

vann:preferredNamespaceURI "http://data.europa.eu/m8g/cpsvap"

In this way the " are escaped, or maybe better to put rdfs:Literal like vann:preferredNamespaceURI^^rdfs:Literal ?

If you indicate an explicit ^^xsd:string datatype, it should force the value as a string literal.
