Handles the sigil `~I` for IRIs.

Note: The given IRI string is precompiled into an `RDF.IRI` struct.

## Examples

|
|

iex> ~I<http://example.com>
|
|
RDF.iri("http://example.com")

Handles the sigil `~B` for blank nodes.

## Examples

Handles the sigil `~L` for plain Literals.

The sigil modifier can be used to specify a language tag.
|
|
|
|
Note: Languages with subtags are not supported.
