New issue 12 by tim...@gmail.com: sadi.py fails to parse valid Turtle
http://code.google.com/p/sadi/issues/detail?id=12

A turtle file [1] that rapper is happy with fails to load when sent to
sadi.py. After quite a bit of attempting to satisfy sadi.py (and rdflib),
I've retreated to dumbing down the input to RDF/XML.

== rapper happy ==

rapper -g -c
add-metadata-materials/sample-inputs/congresspeople-tagged-government.ttl
rapper: Guessed parser name 'turtle'
rapper: Parsing returned 45 triples

== rdflib sad ==

curl -H "Content-Type: text/turtle" -d
@add-metadata-materials/sample-inputs/congresspeople-tagged-government.ttl
http://localhost:9090/add-metadata

rdflib.plugins.parsers.notation3.BadSyntax: at line 1 of <>:
Bad syntax (EOF found when expected verb in property list) at ^ in:
"...atafaqs#> .<http://dsi.lod-cloud.net/dataset/congresspeople>^
#<http://thedatahub.org/dataset/congresspeople> a datafa..."

Comment #1 on issue 12 by elmccar...@gmail.com: sadi.py fails to parse
valid Turtle
http://code.google.com/p/sadi/issues/detail?id=12

Setting the product tag to Product-PythonAPI instead of Product-JavaAPI as
this is a Python issue and not a Java one.

Comment #2 on issue 12 by tim...@gmail.com: sadi.py fails to parse valid
Turtle
http://code.google.com/p/sadi/issues/detail?id=12

We've narrowed it down to the "indented comments" such as:

# links:dbpedia 67
void:subset [
a void:Linkset;
void:target <http://dsi.lod-cloud.net/dataset/congresspeople>,
<http://thedatahub.org/dataset/dbpedia> ;
# http://dbpedia.org/resource
void:triples 67;
];

(it could also be a newline problem - the rest of the file is a comment...)

Comment #3 on issue 12 by mccus...@gmail.com: sadi.py fails to parse valid
Turtle
http://code.google.com/p/sadi/issues/detail?id=12

According to http://stackoverflow.com/a/7241617/438254 curl with -d will
have a tendency to strip newlines. I've added positive and negative tests
to tests.py for this, after having narrowed it down.
