RDF Collection to XML output


Hi all,


why does the CONSTRUCT SPARQL of

PREFIX rdf:<http://www.w3.org/1999/02/22-rdf-syntax-ns#>
PREFIX xsd:<http://www.w3.org/2001/XMLSchema#>
PREFIX as:<https://www.w3.org/ns/activitystreams#>
PREFIX list: <http://jena.hpl.hp.com/ARQ/list#>
CONSTRUCT {<http://resources.semaworx.eu/activity/user/BNNuserPAR>as:items ( ?members ) .}
WHERE{<http://resources.semaworx.eu/activity/user/BNNuserPAR>as:items [ list:member ?members ] .}

produce

<rdf:Descriptionrdf:about="http://resources.semaworx.eu/activity/user/BNNuserPAR";>
    <as:items rdf:parseType="Collection">
<rdf:Descriptionrdf:about="http://resources.semaworx.eu/activity/user/BNNuserPAR/SHA512UIDdateUID004"/>
    </as:items>
    <as:items rdf:parseType="Collection">
<rdf:Descriptionrdf:about="http://resources.semaworx.eu/activity/user/BNNuserPAR/SHA512UIDdateUID003"/>
    </as:items>
    <as:items rdf:parseType="Collection">
<rdf:Descriptionrdf:about="http://resources.semaworx.eu/activity/user/BNNuserPAR/SHA512UIDdateUID002"/>
    </as:items>
    <as:items rdf:parseType="Collection">
<rdf:Descriptionrdf:about="http://resources.semaworx.eu/activity/user/BNNuserPAR/SHA512UIDdateUID001"/>
    </as:items>
  </rdf:Description>

rather than

<rdf:Descriptionrdf:about="http://resources.semaworx.eu/activity/user/BNNuserPAR";>
    <as:items rdf:parseType="Collection">
<rdf:Descriptionrdf:about="http://resources.semaworx.eu/activity/user/BNNuserPAR/SHA512UIDdateUID004"/><rdf:Descriptionrdf:about="http://resources.semaworx.eu/activity/user/BNNuserPAR/SHA512UIDdateUID003"/><rdf:Descriptionrdf:about="http://resources.semaworx.eu/activity/user/BNNuserPAR/SHA512UIDdateUID002"/><rdf:Descriptionrdf:about="http://resources.semaworx.eu/activity/user/BNNuserPAR/SHA512UIDdateUID001"/>
    </as:items>
  </rdf:Description>

??

It’s obviously not the same and caused by the iteration over the queryresults.

But how could I prevent it from happening without having to create aseparate query for the construction ?


As always, input and references are highly appreciated.
