Hello, A remark: In my Marmotta 3.3.0 there is a page to visualize SPARQL query results:/{BASE}/marmottasparql/admin/sgvizler.html. By default it has the following query:
SELECT ?class (count(?instance) AS ?noOfInstances) WHERE { ?instance a ?class } GROUP BY ?class ORDER BY ?class This query can not be executed by Marmotta (400 Bad Request). However, if I change the last line it works well: SELECT ?class (count(?instance) AS ?noOfInstances) WHERE { ?instance a ?class } GROUP BY ?class ORDER BY ?noOfInstances Greetings, Frans
