Funny, but this doesn't work either (I get no results):
SELECT ?prop ?frConstraint
WHERE {
Neutral:FailureRate ?prop ?frConstraint .
FILTER (?prop = spin:constraint)
}

Subject: [tbc-users] SPARQL Query on spin:constraint weirdness
Using TBC 3.0 beta, I have a class (Neutral:FailureRate) that I've
attached a spin:constraint to. When I try to query for the constraint
from the SPARQL tab with:
SELECT ?frConstraint
WHERE {
Neutral:FailureRate spin:constraint ?frConstraint .
}
I get no result. However, when I use:
SELECT ?prop ?frConstraint
WHERE {
Neutral:FailureRate ?prop ?frConstraint .
?frConstraint a sp:Ask
}
I get a result, with ?prop being assigned "spin:constraint". I don't
understand why the first query doesn't return the constraint. Any
ideas? Does it have to do with the Ask query being an anonymous mode?
Thanks
Jeff
