Hi,
I am using this code to construct class instance:
List newResources = new ArrayList<>();
Set reachedTypes = new HashSet<>();
OntModel ontModel = forClass.getOntModel();

SPINQueryFinder.getClass2QueryMap(ontModel, ontModel, property, fa
Hey,
not completely clear from the SPIN spec
(http://spinrdf.org/spin.html#spin-constructors) -- are multiple
spin:constructor values allowed on the same class?
I don't see why not, but just wanted that clarified.
Thanks.

Hey,
I have a somewhat artificial use case where both a class and its superclass
each have an spl:Argument with the same predicate, but different
spl:defaultValue, and possibly other properties:
:Template a spin:Template ;
spin:constraint [ a spl:Argument ;
spl:predicate
There is also the Data Quality Constraints Library:

Hey Holger,
by inspecting SPINConstructors, I have noticed that constructors (and
probably constraints as well?) are "inherited" by walking up the subclass
chain and looking for them. Am I right?
I had a similar use case implemented as custom Jena rules. Properties can
be inferred by construct
Hey Holger,
what is up with the following method in SPINConstructors line 154:
public static void constructInstance(Model queryModel, Resource
instance, Resource type, Model targetModel, List newResources,
Set reachedTypes, ProgressMonitor monitor) {

Holger,
sorry to pick up an old thread.
Why would you want to constrain properties on queries at all? I wouldn't
think they interfere with the rest of your code, as long there is sp:text
among them?
What about adding simple metadata to queries, like dct:title and
dct:description - how do you
Thanks, everything works as expected now.

Slight correction: dqc: is imported indirectly, via gp: ontology.

Hello,
I have a simple piece code that validates an RDF model against SPIN
constraints:
OntModel tempModel =
ModelFactory.createOntologyModel(OntModelSpec.OWL_MEM);
tempModel.add(ontModel).add(model);
SPINModuleRegistry.get().registerAll(tempModel, null);
List cv
Hey all,
I have a query string in sp:text that includes relative URIs, for example:
<> ?p ?o
When I parse the query resource with ARQ2SPIN, what comes out instead is:
?p ?o
Is there a way to control the base URI against which the relative ones are
resolved?
Thanks,
Martynas

Hey,
I have defined a SPIN query using simplified syntax:
[ a sp:Construct ;
sp:text """
CONSTRUCT {
...
}
WHERE {}"""
] .
I am accessing it as Jena Resource. Now how can I add the triples of the
full SPIN RDF syntax? Can the same query bno
Holger,
I've built a QueryBuilder class as part of Graphity:
https://github.com/Graphity/graphity-browser/blob/master/src/main/java/org/graphity/util/QueryBuilder.java
I think it could be useful for many working with Jena and/or SPIN queries,
but I lack expertise of SPIN API to make it robust.
Hey Scott,
I had exactly the same question couple of months ago:
http://tech.groups.yahoo.com/group/jena-dev/message/45839
Couldn't get a definitive answer, so ended up using
URI format
which I've seen an example of somewhere.

I was waiting for SDB 1.3.3 because it was supposed to support
