to Stardog
I have updated to v4.2 from 4.0.5. The first thing I have done is to replace "snarl" in my application by "http", as it says it will be deprecated. However, I get an error from my application when loading some data where before it worked just fine. My Java pom.xml is updated to v4.2. I have tried to use the "db migrate" command as discussed in the manual but it does not exist, apparently. So I have deleted all data and loaded them again but the problem persist. Below is the trace from stardog.log.
What is it happening?

This appears to be a known issue #3197 which has been fixed and will be included in the next release. This is a bug in the underlying library we're using for result serialization.
Cheers,
Mike

Upon further inspection, we realized the error here is different than
the snarl vs http difference. This exception should occur regardless
of which protocol you use and seems to be related to having a literal
in the predicate position during reasoning. Most likely it is caused
by a query pattern like this:
:a ?p ?y
:b :c ?p
If the second pattern binds ?p to literals then the reasoning operator
that handles the first pattern would throw this exception. Is this the
kind of query you are trying? If that's the case a workaround might be
adding a filter to exclude literals explicitly.

Thanks for the hint. I have been checking and I don't have any query like the one you say. So 99% are: ?s ex:xxx ?o
- There are a few ?s a ex:Class
- There is one using:
?role rdfs:subPropertyOf* ex:xxx .
?role rdfs:label ?label .
filter not exists {
?partid ?subproperty ?id .
?subproperty rdfs:subPropertyOf* ?role .
filter ( ?role != ?subproperty ) "
}
- There is one using:
OPTIONAL { ?id ex:xxx ?setA .
?id a ex:A . }
OPTIONAL { ?id ex:xxx ?setB .
?id a ex:B . }
That I used to quickly set a value if the element belongs to a class (so I can use a single query with reasoning and extract the specific subclass)
- There was a ?s ex:unexisting_in_the_ontology ?o that gave me a warning in stardog.log saying that it will be treated as a PROP. But I have removed it and the problem persists.
All the rest are normal ?s ex:xxx ?o.
So the 6 - 7 queries run normally on 4.0.5 but as soon as I switch to 4.2, something fails (I believe it also failed with 4.1 when I tried long ago, so I switched back to 4.0.5, but I am not sure it was for the same reason).
Thanks.

The problem is in this query:
> ?role rdfs:subPropertyOf* ex:xxx .
> ?role rdfs:label ?label .
> filter not exists {
> ?partid ?subproperty ?id .
> ?subproperty rdfs:subPropertyOf* ?role .
> filter ( ?role != ?subproperty ) "
> }
The pattern ?subproperty rdfs:subPropertyOf* ?role may actually return
literals due to the semantics of * operator in SPARQL property paths.
But since you are already using reasoning for these queries and
rdfs:subPropertyOf is transitive you can simply drop * (both in the
filter and above) and the problem should go away.
A better solution here would be to use the Stardog's built-in
strictSubPropertyOf function [1]. So instead of
> ?subproperty rdfs:subPropertyOf* ?role .
> filter ( ?role != ?subproperty ) "
you can simply do
> ?subproperty stardog:property:strictSubPropertyOf ?role .
The strictSubPropertyOf handles transitivity but excludes equivalent
properties so you don't need the extra filter.

You are totally right. I traced the error down and the problem was that query. I changed it as you suggested and everything works fine with Stardog 4.2.
The query needed to get all subproperties of a superproperty but then use the specific assertion. I recall there was a problem and that is why I used the "*", but can't remember what it was. I will investigate further. In the meantime, it seems to work just fine now. Many thanks.
You're the man!
PS: Is there any benefit of using stardog:property:strictSubPropertyOf appart from clarity? I read it is only syntactic sugar.
