Hello,
I think the right syntax should be
PREFIX fedora: <info:fedora/fedora-system:def/relations-external#>
SELECT ?a
FROM <#ri>
WHERE {?a fedora:isConstituentOf <info:fedora/Demo:2>}
or
SELECT ?a
FROM <#ri>
WHERE {?a <info:fedora/fedora-system:def/relations-external#isConstituentOf>
<info:fedora/Demo:2>}
If you use a PREFIX you shouldn't put the brackets ; they are implied
by the prefix.
