Summary:                    Language tags with underscore
Description: 
The N-Triples parser complains with "zh_pinyin" language tags.  Probably that's
a problem with the data provider (IIRC one should use dash instead of
underscore: zh-pinyin).

Steps to Reproduce: 
$ rapper http://linkedgeodata.org/triplify/node424310680 | rapper -i ntriples -c
- http://ex.org
rapper: Parsing URI http://linkedgeodata.org/triplify/node424310680 with parser
rdfxml
rapper: Serializing with serializer ntriples
rapper: Parsing file <stdin> with parser ntriples and base URI http://ex.org
rapper: Error - URI http://ex.org:166 column 132 - Illegal bNodeID - _ not
followed by :
rapper: Error - URI http://ex.org:166 column 132 - Missing terminating "."
rapper: Parsing returned 225 triples
rapper: Parsing returned 224 triples
$ rapper --version
2.0.14
$ 

Additional Information: 
Not urgent, I might ping the linkedgeodata.org guys to fix their data.

I am writing Ada bindings for Raptor.

I've stumbled with the function raptor_uri_resolve_uri_reference().

raptor_uri_resolve_uri_reference() has "length" argument. How to calculate this length? It seems a wrong API.

>From the source:

 * @base_uri: Base URI string
 * @reference_uri: Reference URI string
 * @buffer: Destination buffer URI
 * @length: Length of destination buffer

So it reads @base_uri and @reference_uri and outputs ( writes) to @buffer
which must be pre-allocated to @length bytes.

... although it seems that function doesn't check it.  Oops.

To be safe, you can use a buffer of size
  strlen(base_uri) + strlen(reference_uri) + 1
which is what raptor_new_uri_relative_to_base_counted() uses

tells something about "sinks".

What is a sink?

(I am writing thick Ada2012 bindings for Raptor.)

In *nix terms, it's /dev/null - it provides an empty iostream (read) or
throws away all output (write)
