Question 1 of 4

1. Question

Which of the following best describes the relationship between the Resource Description Framework (RDF) and its serializations?

RDF is specifically an XML file format, and other serializations are just compressed versions of it.
Correct Incorrect Correct answer

RDF is an abstract, mathematical graph model, while formats like Turtle and JSON-LD are concrete ways to write it down.
Correct Incorrect Correct answer

RDF is a visual modeling tool, while serializations are the underlying database queries used to access it.
Correct Incorrect Correct answer

RDF and its serializations are completely identical, meaning an RDF graph can only exist as an RDF/XML file.

To convert a blank node into a directional language-tagged literal for international rendering.
Correct Incorrect Correct answer

To delete all blank nodes from a graph to improve SPARQL query performance.
