Question

What would the parser Control command -BASE=URI do?

a) Sets the base URI for resolving relative URIs in RDF data
b) Specifies the RDF serialization format
c) Validates RDF data against a specified schema
d) Enables strict mode for the parser

Answer 1

The command -BASE=URI in an RDF parser sets the base URI for resolving relative URIs in RDF data, ensuring that all relative URIs are interpreted in the context of the provided base.

Step-by-step explanation:

The parser control command -BASE=URI sets the base Uniform Resource Identifier (URI) for resolving relative URIs within Resource Description Framework (RDF) data. When working with RDF data, it is sometimes necessary to resolve relative URIs against a base URI to obtain the full URI references that are used within the RDF statements.

This is particularly useful when dealing with data that has been obtained from a document that has its own base URI, such as an RDF document embedded in an HTML page where the base can be set to the document's URI. By using the -BASE option with a specified URI, the parser will interpret all relative URIs in context with the given base.
