    <p>I am trying to query DBpedia using SPARQLWrapper in Python (v3.3).

    2. COPlease show your python code. Your query is legal, according to sparql.org's validator, and it only has one line, so if there are 118 lines of something, it's probably the results, but we can't see what you're trying to do with them. Also, please show the error message verbatim (i.e., copy and paste it here). It could be that the DBpedia results are being read in an unexpected way. How are you making the query?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
