Ptter:
Sorry i didn't better describe my problem; can't fix it if i can't show it's broken
(or that it appears broken in this case).
At quebec.bio2rdf.org/sparql, i do:
select *
where
{
<http://bio2rdf.org/go:0004003>
<http://bio2rdf.org/bio2rdf#isA>
$o
}
and get its 3 parent categories back, but if i do the same query on, say, go:0005488, i get nothing back.
As i looked at this some more, it turned out that i lost the upward links for all three parents of go:0004003 after one or several successful links.
but other stuff confuses me too. for example:
if i do:
select *
where
{
<http://bio2rdf.org/go:0004003>
$p
$o
}
limit 1000
and examine the predicates, i see 3 #isA predicates, but if i look at 5488, i see no #isA predicates.
I hope this is a little clearer, and thanks,

The quebec.bio2rdf.org/sparql server is reasonably out of date. It hasn't been updated recently.
If you want to query GO you would be better using the go.bio2rdf.org/sparql endpoint, or downloading the source file from http://quebec.bio2rdf.org/download/n3/go.n3.gz and putting it into your local rdf store.
closing because of no recent activity. comment if still necessary.
