Description
In my 500M+ triple dataset, queries seem to be failing for no clear reason. Here's an example.
prefix Products: <http://www.example.com/test/Products#>
select ?p ?o
where {
Products:ABC ?p ?o .
}
...results in a list like:
Products:HasComponent Products:DEF Products:HasComponent Products:GHI
Now running this query:
prefix Products: <http://www.example.com/test/Products#>
select ?p
where {
Products:ABC ?p Products:DEF .
}
...has no results. How is this possible?
Here's another example.
prefix Products: <http://www.example.com/test/Products#> ask where { Products:ABC Products:PartNumber ?p . filter ( ?p = "ABC" ) }
This returns "True"
prefix Products: <http://www.example.com/test/Products#> ask where { ?s Products:PartNumber ?p . filter ( ?p = "ABC" ) }
This returns "False"
What other info can I provide?
