  • Use semantics in MarkLogic
  • Describe what a triple is and where triples come from
  • Load triples into MarkLogic
  • Know when to use embedded triples
  • Enable a triple index
  • Describe what SPARQL is
  • Write SPARQL queries
  • Use functions and filters in SPARQL queries
  • Specify the serialization of query results
  • Write search and SPARQL combination queries
  • Fetch and store triples from public repositories
  • Write path expressions to traverse a semantic graph
  • Implement inferencing
  • Update triples and graphs
  • Access additional learning resources
