Duplicated authors in PDF metadata

[okarras]

It seems to be possible to annotate the authors (and probably the title) several times in a paper and every annotation is added to the PDF metadata. I found one paper that has a duplicated list of authors, leading to an issue when importing the data into the ORKG.

Any idea how to prevent this problem?

Literally the authors are indeed duplicated in the presented data, but semantically they are not: Semantically, the authores are simply declared twice, which should only be slightly wasteful of space within the PDF file, and should not cause trouble for proper parsers of the semantic data.

It would be a different matter if the authors were declared like this:

    dc:creator [
        rdf:_1 "Ian Valentin Christensen"@da ;
        rdf:_2 "Jonas Smedegaard"@da ;
        a rdf:Seq
    ] ;

When declared as an ordered list, it would be semantically problematic if authors were repeated - not that they would double in amount, but it would become illogical which sorting order they were supposed to be represented.

I further checked the original annotated paper with the authors.

The authors have not been annotated / declared twice, instead the command seems to be executed two times while compiling the PDF resulting in the duplicated authors.
