Body
It's still not entirely clear to me what you're trying to achieve and why the example update that you give is not doing what you want, but if the aim is to have an update that replaces triples for a given subject, you could do something like this: <pre class="lang-sql prettyprint-override"><code>@prefix rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#> @prefix ex: <http://example.org/> DELETE {?s ?p ?o} INSERT {?s ex:title "foo" ; ex:description "bar" ; rdf:type ex:FooBar . } WHERE { ?s ?p ?o . FILTER (?s = ex:subject1) } </code></pre> The above operation will delete all existing triples with <code>ex:subject1</code> as the subject, and insert a new title, description, and type. Or if you don't like filters, you can also formulate the above like this: <pre class="lang-sql prettyprint-override"><code>@prefix rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#> @prefix ex: <http://example.org/> DELETE {ex:subject1 ?p ?o} INSERT {ex:subject1 ex:title "foo" ; ex:description "bar" ; rdf:type ex:FooBar . } WHERE { ex:subject1 ?p ?o . } </code></pre> If you only want to delete specific properties for a given subject (rather than all triples with that subject), you can modify the operation like so: <pre class="lang-sql prettyprint-override"><code>@prefix rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#> @prefix ex: <http://example.org/> DELETE {ex:subject1 ex:title ?t ; ex:description ?d ; rdf:type ?c . } INSERT {ex:subject1 ex:title "foo" ; ex:description "bar" ; rdf:type ex:FooBar . } WHERE { ex:subject1 ex:title ?t ; ex:description ?d ; rdf:type ?c . } </code></pre>

1. COThank you very much for taking the time to provide such a detailed example. I will run some queries in the Virtuoso interface to illustrate my need, and will test your suggestions. If they work for me, this will be the accepted answer.

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.
