[ckan-dev] Escaping strings in N3 output

[Joshua Tauberer]

Hi again,

I was able to edit the package .rdf RDF/XML output template to add new 
predicates. For instance, we store URIs in an extras field to reliably 
identify the author of a dataset.

   example: 
http://hub.healthdata.gov/dataset/2008-basic-stand-alone-carrier.rdf
      our template adds dct:creator / dc:publisher nodes

Now I'm trying to bring the N3 template up to date with the RDF/XML 
template changes. However I'm finding that strings aren't escaped in the 
output, so embedded quotes in extras field values (for example) bust the 
file if I have something like this in the template:

    dc:subject "${extra_dict.get('value','')}";

because it may generate

    dc:subject "quote chars "here" break N3 syntax";

Is this a bug? A limitation? I know that Genshi doesn't know what N3 is, 
so I'm not entirely expecting CKAN to be able to handle this easily. 
It's fine if it's not really supported --- this is just icing on the 
cake for us. The RDF/XML works fine for us.
