## Unreleased

### Added

- `RDF.IRI` as a more suitable URI/IRI representation for RDF, bringing enormous
  performance and memory-consumption benefits

### Changed

- use `RDF.IRI` instead of Elixirs `URI` everywhere
- use the term _iri_ instead of _uri_ consistently, leading to the following 
  function renamings:
    - `base_iri` instead of `base_uri` for the definition of `RDF.Vocabulary.Namespace`s
    - `__base_iri__` instead of `__base_uri__` in all `RDF.Vocabulary.Namespace`s
    - `__iris__` instead of `__uris__` in all `RDF.Vocabulary.Namespace`s
    - `RDF.IRI.InvalidError` instead of `RDF.InvalidURIError`
    - `RDF.Literal.InvalidError` instead of `RDF.InvalidLiteralError`
    - `RDF.Namespace.InvalidVocabBaseIRIError` instead of `RDF.Namespace.InvalidVocabBaseURIError`

### Fixed

- when trying to resolve a term from an undefined module a `RDF.Namespace.UndefinedTermError`
  exception
