Hi Holger,
Thank you for your answer.
I need to export taxonomy (both all and only separate nodes) to
Turtle, RDFXML and JSON formates.
I need to be able to import exported taxonomies to evn as new ones
again. That's way skos:conceptScheme and skos:hasTopConcept
relationships must be presented in the export result.
If i am exporting all taxonomy as is, there are no problems.
But, If i need to export only separate nodes from taxonomy (that may
not connect to existing hasTopConcept relation), i need to put correct
skos:hasTopConcept relation to be able to import result into evn again.
For these reasons i try to modify resulting file on sml:performUpdate
step.
So, using sml:ApplyConstruct, I am not able to pass resulting grapf to
next steps for modifying. I am only able to pass result to the
final sml:ReturnRDF step. Am I correct?
Yes. However, you could follow one sml:ApplyConstruct with another
sml:ApplyConstruct, e.g.
CONSTRUCT {
?s ?p ?o .
}
WHERE {
{
?s ?p ?o .
FILTER (?p != skos:hasTopConcept) .
}
UNION
{
?s skos:hasTopConcept ?old .
BIND (skos:hasTopConcept AS ?p) .
BIND (IRI(?nodeURI) AS ?o) .
}
}
which will basically copy all previous triples, only replacing the
objects in skos:hasTopConcept triples. (Untested)
It really depends on how complex your queries will become, and what else
you need to do.
If so, what others features inside of sparqlmotion technology are
suitable for my scenario?
sml:FilterByConstruct is another relevant feature.
If they don't exists, i will to rewrite on swp.
With SWP's ui:return, out of the box, we currently only support
serializing Turtle back, so RDF/XML would not work.
Anyway, I think if the scenario is just about producing a graph with a
few triples modified as above, I would try to put everything into a
single CONSTRUCT query and wrap this into a SPIN template. Then use the
SPIN template servlet to return it. The SPIN template servlet does
support all three serializations that you mention.

Hi Everyone,
I use evn 5.3.
I try to write sparqlmotion script thats exports exports taxonomies.
I need to change skos:hasTopConcept property in result set.
For make this do next:
1. For building resultset I use sml:ApplyConstruct with query inside:
CONSTRUCT {
?a ?b ?c .
}
WHERE {
{
SELECT ?a ?b ?c
WHERE {
{
{
BIND (IRI(?selectedGraph) AS ?graphName) .
BIND (IRI(?nodeURI) AS ?taxUri) .
GRAPH ?graphName {
?a (skos:broader)* ?taxUri .
?a ?b ?c .
} .
} .
}
UNION
{
BIND (IRI(?selectedGraph) AS ?graphName) .
GRAPH ?graphName {
?a a skos:ConceptScheme .
?a ?b ?c .
} .
} .
}
} .
}
2. on the next step I try to use the sml:PerformUpdate
2.1. In case of using next query:
DELETE {
?a skos:hasTopConcept ?oldValue .
}
INSERT {
?a skos:hasTopConcept ?newValue .
}
WHERE {
BIND (IRI(?nodeURI) AS ?newValue) .
?a ?b ?c .
?a skos:hasTopConcept ?oldValue .
}
I got NullPointerException in log
