SPARQL query using rdf:resource

[randal]

Here's a snippet from an rdf file (converted from .ics to rdf):

    <Vevent>
      <created>20080217T132152Z</created>
      <lastModified rdf:parseType='Resource'>
        <dateTime>2008-02-17T16:32:09Z</dateTime>
      </lastModified>
      <dtstamp rdf:parseType='Resource'>
        <dateTime>2008-02-17T16:39:51Z</dateTime>
      </dtstamp>
      <uid>db12e1de-7934-4fd9-939a-ace7bd01795d</uid>
      <summary>Surely available</summary>
      <dtstart rdf:parseType='Resource'>
        <dateTime>2008-02-20T16:00:00</dateTime>
        <tzid>/mozilla.org/20070129_1/Asia/Manila</tzid>
      </dtstart>
      <dtend rdf:parseType='Resource'>
        <dateTime>2008-02-20T17:00:00</dateTime>
        <tzid>/mozilla.org/20070129_1/Asia/Manila</tzid>
      </dtend>
      <transp rdf:resource='http://www.w3.org/2002/12/cal/ical#transparent'/>
    </Vevent>

I want to query my rdf calendar about the dates of transparent and opaque events. However I'm not sure how to deal with rdf:resource on SPARQL.

Here's my query so far:

PREFIX ical: <http://www.w3.org/2002/12/cal/ical#>
PREFIX xsd: <http://www.w3.org/2001/XMLSchema#>
PREFIX rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#>
SELECT $s WHERE{
    $e a ical:Vevent .
    $e ical:dtstart $d .
    $d ical:dateTime $s .
}

This is will just display all dateTimes of start dates of all events. I want to get all the dateTime of dtstarts of a transparent event. I hope someone can help me on this...

Thanks.

$e ical:transp <http://www.w3.org/2002/12/cal/ical#transparent>

did the job.

I want to query my rdf calendar about the dates of transparent and opaque
events. However I'm not sure how to deal with rdf:resource on SPARQL.

Here's my query so far:

PREFIX ical: <http://www.w3.org/2002/12/cal/ical#>
PREFIX xsd: <http://www.w3.org/2001/XMLSchema#>

SELECT $s WHERE{
   $e a ical:Vevent .
   $e ical:dtstart $d .
   $d ical:dateTime $s .
}

to get all the dateTime of dtstarts of a transparent event. I hope someone
can help me on this...
