schema:nationality 'expects' instance of schema:Country

[bencomp]

Looking at the schema:nationality documentation, I think a schema:Person's nationality should have an instance of a schema:Country as object value instead of a code as string.

I'm not sure what list the country codes are from, but perhaps you could adjust

thes2rdf/nta2rdf.sh

Line 81 in 2c01f89

line=$(echo $line | sed "s@</schema:Person>@<schema:nationality>$natio</schema:nationality></schema:Person>@")

to refer to an rdf:resource=".../$natio".

What kind of codes are used in field 019@? I'm not familiar with the PICA+ record format...
