Final answer:
The -CHECK command in parser Control is used to check for syntax errors in RDF data, ensuring RDF code adheres to the correct structure and rules.
Step-by-step explanation:
The parser Control command -CHECK is used to check for syntax errors in RDF data. RDF stands for Resource Description Framework, and it is a standard for encoding, exchange, and reuse of structured metadata. The -CHECK command does not validate RDF data against a specified schema, enable debugging mode, or perform semantic analysis. Instead, it ensures that the RDF code is syntactically correct, which means it follows the rules and structure defined by RDF specifications. This is crucial for the interoperability of web data, as even minor syntax errors can lead to issues in processing or interpreting the data.
