> Let's say that in 2024 Trump wins again. How will the data get represented in RDF-star? Since RDF-star, like RDF, has "no duplicate triples" constraint, the data creator has to extend the schema to introduce a new structure that involves a new property, :occurrenceOf. Since the above query was written without expecting the new structure, it has to be modified as well.


Souri –

I’m not sure I understand the issue here. Won’t the original query work just fine if the input data contains an extra index value?

<< :Trump :servedAs :President >> :index 45, 47 .

=>

:Bush
:Obama
:Trump
:Biden
:Trump

Thanks,
