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?
If so, what others features inside of sparqlmotion technology are suitable
for my scenario?
If they don't exists, i will to rewrite on swp.
