In a csvw:Table logical source, it seems that the csvw:header is not taken into account: the first line is always skipped whatever the value.
I've tried with:
csvw:header false
csvw:header true
csvw:header "false"^^xsd:boolean
csvw:header "true"^^xsd:boolean
csvw:header "0"^^xsd:boolean
csvw:header "1"^^xsd:boolean
And in https://github.com/RMLio/rmlmapper-java/tree/master/src/test/resources/test-cases-CSVW, I can't find a test specifically on this property.
I'm using RMLMapper with Docker in the currently latest version (sha256:41809fff4d1cd0abb93d1f742bc5890b7a744788753a56325c850f8bb9dcb212) (Dec. 2025).
