Direct look-up of resources with urlencoded URIs does not work #145

frodeseverin · 2012-10-11T12:22:27Z

I have the following URIs in my KB:

The first one works with fine in OntoWiki, the second does not, but rather produces the error message:

As noted in #145, direct lookup of URI's with international characters, i.e. containing urlencoded strings, does not work.

Further investigation into the matter, as detailed in AKSW/RDFauthor#15, revealed that viewing these URI's from within OntoWiki is also problematic.

Example:
http://data.bbib.no/view/r/Nordahl_Grieg
has the property
frbr:creatorOf http://data.bbib.no/data/Ung%20m%C3%A5%20verden%20ennu%20v%C3%A6re%20%3A%20roman
which in turn has the property
rdfs:label "Ung må verden ennu være : roman"

However, it seems that the URI is urlencoded twice, at least partially. When I paste
http://data.bbib.no/data/Ung%20m%C3%A5%20verden%20ennu%20v%C3%A6re%20%3A%20roman
into the View Resource box of OntoWiki and hit the button, I am directed to this URL:
http://data.bbib.no/resource/properties?r=http%3A%2F%2Fdata.bbib.no%2Fdata%2FUng%2520m%25C3%25A5%2520verden%2520ennu%2520v%25C3%25A6re%2520%253A%2520roman
The source for this resource

<http://data.bbib.no/data/Ung%20m%C3%A5%20verden%20ennu%20v%C3%A6re%20%3A%20roman> rdfs:label "Ung må verden ennu være : roman" .

is correct, but the URL in the address bar is not, thus causing problems in the OntoWiki interface. The URL that appears in the address bar of the browser when clicking on the label "Ung må verden ennu være : roman" in the OntoWiki resource view
http://data.bbib.no/data/Nordahl_Grieg
is
http://data.bbib.no/view/r/Ung%2520m%25C3%25A5%2520verden%2520ennu%2520v%25C3%25A6re%2520%253A%2520roman
which is yet different, and now produces the error message

Interestingly, links to exsternal IRI's seems to be handled differently, albeit still wrong.

I added

@base <http://data.bbib.no/data/> .
<Nordahl_Grieg>  m:plays <http://data.bbib.no/data/husvask%20er%20fint>,
    <http://data.bergenbibliotek.no/data/husvask%20er%20fint> .

to my knowledge base by way of the

Now, following the first of these links in OntoWiki points my browser to
http://data.bbib.no/view/r/husvask%2520er%2520fint
which renders the said error message

OntoWiki Error

However, following the latter of the two links lands my browser at

To actually see what is represented at the different URL's you'd have to instantiate the model for your browser by visiting http://data.bbib.no/ once prior to following the links.

This situation is due to some strange behaviour of the DefaultModel extention, possibly misconfiguration on my part.
