Final answer:
The SPARQL 1.1 Query Results JSON Format is used for Data Retrieval by providing a standardized JSON representation of the results of a SPARQL query, facilitating easy parsing and integration with applications.
Step-by-step explanation:
The SPARQL 1.1 Query Results JSON Format provides d) Data Retrieval. It is a standardized format used to express the results of a SPARQL query. SPARQL stands for SPARQL Protocol and RDF Query Language, which is used to retrieve and manipulate data stored in Resource Description Framework (RDF) format. The JSON results format is particularly useful because it allows the results to be easily parsed and integrated with web applications and other programming environments that handle JSON natively. As an example, when a SPARQL query is executed, it might return a set of variables and their corresponding values; the SPARQL 1.1 Query Results JSON Format will represent this information as a JSON object, which can then be used for further data processing or presentation.
