def domain_subdomain_viewer():

    Display all unique domain and subdomain values from an RDF ontology file.

    This function parses the RDF graph from the given file path and prints the unique
    values of the predicates `mds:hasDomain` and `mds:hasSubDomain`. Uniqueness is determined
    in a case-insensitive manner.

    Prints:
        - A list of unique domain values.
        - A list of unique subdomain values.
