SWT Lab 3
This document outlines lab assignments for working with RDFS and Sesame. The first assignment asks students to write an ontology in Turtle syntax and load it into Sesame, printing all triples including entailed ones. The second assignment asks students to create a simple RDFS forward chaining inference engine using Sesame that covers all entailment rules except rdfs1 and datatype rules, and verify it works using the example ontology.

- 3. + Lab Assignment 3(part 1) Write the ontology from FSW Chapter 2.6 (page 67) in a file named ontology.ttl in turtle syntax. Then, use Sesame, RDFS and SPARQL to: Load Print all triples of the model (including the entailed ones) to a file named “rdfs-output.ttl”
- 4. + Lab Assignment 3-5(part 1) Create a simple RDFS Forward chaining inference engine Use Sesame to store and load the triples Use SPARQL to “infer all new triples”, hint use CONSTRUCT and ASK queries to ease the development You should cover all entailments except: rdfs1 and the Datatype entilament rules (rdfD1, rdfD2, rdfD3) Verify using the ontology from the previous examplle Note: Name your main class org.example.RDFSFowardChainingEngine
