Using the SWP control element ui:forEach to iterate through the collection of SKOS concepts that are associated with the current concept (?this) via the skos:narrower relationship.

Whenever SELECT queries are embedded into the document, they must be surrounded by {# ... }. For each row of the ui:resultSet query, the block inside of the ui:forEach will be repeated.

The result variables of the query (here: ?child) will be visible inside of that block, and we can use them to populate an HTML list.

Resulting HTML as rendered in the Browser. Current concept in this case is Spiders from the Agrovoc SKOS file describing a classification of animals.
