Interesting Observations

This is straightforward use of exhibit (directly loading RDF and display it)

Technology Highlights

Simile Exhibit was used to load RDF directly
 
 <link rel="exhibit/data"
       href="http://data-gov.tw.rpi.edu/raw/92/data-92.rdf" 
       type="application/rdf+xml"
       charset="utf-8"/>

Note that Exhibit requires all instances to have their class membership defined.The Exhibit TabularView and Exhibit Timeline views were used in this demonstration.
 <div ex:role="view"
      ex:viewClass="Exhibit.TabularView"

      ex:label="Table"
      ex:columns=".title, .url, .agency, .category, .geographic_coverage, .date_released, .data_gov_data_category_type, .description"
      ex:columnLabels="title, url, agency, category, geographic_coverage, date_released, data_gov_data_category_type,  description"
      ex:columnFormats="list, list, list, list, list"
      ex:sortColumn="1"

      ex:sortAscending="false"
      ex:rowStyler="rowStyler">
 </div>
 <div ex:role="view" 
      ex:viewClass="Timeline"

      ex:start=".date_released"
      ex:topBandUnit="year"
      ex:topBandPixelsPerUnit="50"
      ex:bottomBandUnit="decade"
      ex:bottomBandPixelsPerUnit="50"

      ex:bubbleWidth="400"
      ex:bubbleHeight="250">
 </div>
