Case 2: Graph Walk (Querying)
Explore how to query RDF graphs using SPARQL within Elixir by walking through DBpedia data. Understand recursive graph traversal techniques and learn to browse linked data by dereferencing URIs, enabling local queries on graph fragments for meaningful navigation across semantically connected data.

Let’s take a short walk through DBpedia. We’ll do this in two different ways—first by querying DBpedia and second by browsing DBpedia. Let’s start with querying.
Module creation
The first thing we do is create a new module. We create a new folder named examples/ under our rdf_graph/lib/rdf_graph/ folder. Under that, we create a walk_query.ex ...
