Same 1-hop and 2-hop CONSTRUCT queries as Step 1, but run against graph-02.ttl to show the result of literal-to-IRI transformations.
Add namespace prefixes (rdfs, migrants, person, personp, work, workp, location, locationp) to query files. Use --prettify in Rake tasks so example files use abbreviated IRIs. Fix 2hop task to use graph-02.
