### Changed
|
||||
|
||||
- Rename `RDF.Statement.convert*` functions to `RDF.Statement.coerce*`
|
||||
- Don't support Elixir versions < 1.4
|
||||
|
||||
### Fixed
|
||||
|
||||
- `RDF.uri/1` and URI parsing of N-Triples and N-Quads decoders preserve empty fragments
|
||||
- booleans weren't recognized as convertible literals on object positions
|
||||
- booleans weren't recognized as coercible literals on object positions
|
||||
- N-Triples and N-Quads decoder didn't handle escaping properly

RDF statements are generally represented in RDF.ex as native Elixir tuples, either as 3-element tuples for triples or a 4-element tuples for quads.

The `RDF.Triple` and `RDF.Quad` modules both provide a function `new` for such tuples, which convert the elements to proper nodes when possible or raise an error when such a conversion is not possible. In particular these functions also resolve qualified terms from a vocabulary namespace. They can also be called with the delegator functions `RDF.triple` and `RDF.quad`.
