Hi,
I just wanted to check if I'm misunderstanding the behavior of
spin:constructor.
I built a toy system with one class (Thing_1) containing a spin:constructor
that creates a single triple:
CONSTRUCT {
?this rdfs:label ?type .
}
WHERE {
?this a ?type .
}
So far so good. I can go to Instance view and create an instance, and sure
enough, it gets created with the label set to the rdf:type.
Here's the problem:
I create a separate file that declares a single triple:
data:Thing_1_1
rdf:type constructorTest:Thing_1 ;
.
If I import that file into the class-declaration file, I expect the
constructor to fire. But no, nothing happens.
My question is, why not? What constitutes the act of creating a new
instance?
I have attached the two toy files in case that makes it easier to understand
my question.
(My motivating goal is, given a large data file, I want a bunch of
properties to get populated when I import it. I had been using spin:rules to
do that, but I want to reserve the rules for subsequent calculations, once
all those initial properties get created.)
