sparql union does not return variables defined outside the union graph e.g. a query of the following type will return value for ?x but ?a, ?b, and ?c will have no values or rather they all have a value of string 0 instead of a literal or a resource object value.
SELECT ?a ?b ?c ?x
WHERE {
{ ?x pred1 ?a .
?x pred2 ?b .
OPTIONAL {?x pred3 ?c . }
}
{ { ?x...

I cannot make uniting models from database work very reliably with SPARQL. E.g.
$TestModel1 = $TestDatabase->getModel("test1");
$TestModel2 = $TestDatabase->getModel("test2");

Both $TestModel1 and $TestModel2 work fine separately and I can query them with SPARQL. I can also see these models in SQL table when I query the statements...

$sparql_query = '
...
FILTER line 1
line 2 ';
and use several lines it does include something that causes problems. I'm not sure how the standard would like to deal with these newlines but maybe you are right and they should stay. I'm taking the newlines out already but it is just...

I had a lot of weird problems and error messages when I unzipped code in Windows while I was using it in Linux. It added newline/return characters. Maybe you had something similar.
Now I'm having problem with newlines in SPARQL Filter. I cannot use newlines in the Filter string I create in PHP. I can work around this but it would be nice if the newlines could be just ignored when parsing the...
