Resource URI's with urlencoded characters are problematic #151
Comments

Importing the above Turtle source into an empty knowledge base in OntoWiki exaplifies the problem. Note that following the link for "Performs" under the "Emmerich Kálmán" resource does not work. However, expanding the resource by clicking the "+" icon does. Replacing "Agent%2FEmmerich_K%25C3%25A1lm%25C3%25A1n" in the URL address bar of the browser with "fr%25C3%25B8hode%2520p%25C3%25A5%2520tur" displays a page for the resource in OntoWiki. |

Now here is an interesting discovery: The error now seems to stem mainly from some of the the links generated in the user interface, which are handled wrongly in the Rewrites on nginx. I'll try to switch to Apache, and see whether that makes any difference to the Rewrite situation. Anyway, here is an example: http://data.bbib.no/view/?r=http%3A%2F%2Fdata.bbib.no%2Fdata%2FAgent%2FBj%25C3%25B8rnstjerne_Bj%25C3%25B8rnson If, however, I try to navigate from the resource page of 'Fire Digte ...' I'll be back with more info. ;)Frode |

I have now tested this with Apache, and that gives the same results. Clicking the object link of 'nid3:textWriter' in the resource view of "Fire Digte ..." in OntoWiki lands my browser at The data for Bjørnson is stored at this URI The Linked Data Server does not work for the resources with international queries. There seems to be something wrong both in the parsing of resource links, both in the production of HTML tags for the interface, and in the consumption of the resource URI's in the scripts handling the parameters to ;)Frode |
This issue is related to issue #145. The issue is discussed at length there. However, I need to clarify a few things. Hence this separate issue.
Whenever there exists in the knowledge base resources with special characters in their names, things does not work as expected. Links are broken, and some views, such as the "Source" tab, does not work properly.
I have created a test resource to explain the problem. Theese are created using OntoWiki. As can be seen, the Turtle source is correct, but the OntoWiki interaction with them are not.
