While I continue to wrestle with screencast production etc.. Here is are some screenshots that guide you through the process of providing Data Web URIs to the SPARQL Query Builder (first cut of an MS Query or MS ACCESS type tool for the Data Web).

  1. Step 1 - Enter a Data Source URI
  2. Step 2 - Click on the Run Control (">" video control icon)
  3. Step 3 - Interact with Custom Grid hosted results (comprised of Resource Identifiers (S), Properties (P), and Property Values (O).

Once you grasp the concept of entering values into the "Default Data Source URI field", take a look at: http://programmableweb.com and other URIs (hint: scroll through the results grid to the QEDWiki demo item)
