Hello,

I have a question concerning validation of RDF models against
RDF Schema. Is this feature supported by RDF API ?

Thanks.

Hallo,

I am new to RDFAPI-PHP but very impressed by the careful design and the
good documentation. I am stuck with a problem, however, and thought you
might be able to help me:

I have a hierarchical folder structure in my database which I want to
display in a Mozilla XUL Tree Widget that can natively use the RDF as a
datasource.

$db     = $rdf->getNewModel($datasource);
$dbRes  = new ResModel($db);

if I create a root sequence like so:

$treeRootSeq  = $dbRes->createSeq("urn:bibliograph:folder#root");

and programmatically add members of the sequence:

$folderRes      =
$dbRes->createResource("urn:bibliograph:folder#(newFolderId goes here)"); 
$treeRootSeq->add( $folderRes );

the generated RDF looks like this:

<rdf:Description rdf:about="urn:bibliograph:folder#root">
<rdf:_2
rdf:resource="urn:bibliograph:folder#89e51c22d059c6abde622855aa7f5321"/>
</rdf:Description>

....

<rdf:Seq rdf:about="urn:bibliograph:folder#828679db024d9dc591676782c63b949d">
<rdf:_1
rdf:resource="urn:bibliograph:folder#92eb042f602b699051344f1b2e25c12f"/>
<rdf:_2
rdf:resource="urn:bibliograph:folder#6c00094831008383d4e1b9cba22bf30f"/>
<rdf:_3
rdf:resource="urn:bibliograph:folder#48a124b55bfa09881264c0342d419a50"/>
</rdf:Seq>

What I would like to have, however, is this:

<rdf:Description rdf:about="urn:bibliograph:folder#root">
   <rdf:Seq>
       <rdf:li
rdf:resource="urn:bibliograph:folder#92eb042f602b699051344f1b2e25c12f"/>
       <rdf:li
rdf:resource="urn:bibliograph:folder#6c00094831008383d4e1b9cba22bf30f"/>
       <rdf:li
rdf:resource="urn:bibliograph:folder#48a124b55bfa09881264c0342d419a50"/>
    </rdf:Seq>
</rdf:Description>

How do I have to code this?

Thanks,

Christian

I want to develop an application to execute SPARQL queries in order to find resources according to user specific queries. For that i need to integrate the user interface with a SPARQL engine. Can anyone help me suggestions how i could integrate the user interface with a SPARQL engine?

I think the most difficult part of introducing the semantic web to the
users is the interface. Sometimes I think the interface should be as
specialized as possible and hide the interesting/macabre power of the
SW to the user and do the magic in the backend. Sometimes I'm sure we
need to teach users SPARQL :)

In dbpedia.org / online access you'll find some examples. I would like
to see other interfaces, too
