Java-based readings

This page suggests Java-based readings as an alternative to the Python-based materials, if you prefer that.

Lecture 1: Knowledge Graphs

Themes:

• Jena

Mandatory readings:

• Apache architecture overview (mandatory)
• The core RDF API (mandatory)
• An introduction to RDF and the Jena RDF API (mandatory)

Useful materials:

• Welcome to Apache Jena (useful starting page)
• Apache Jena main page (useful starting page)
• Jena tutorials (useful starting page)
• Package org.apache.jena.rdf.model (supplementary, but necessary for the labs and project - lab 1 and the lecture notes lists the classes and methods you should look at)

Lecture 2: RDF

Themes:

• Programming RDF in Jena

Mandatory readings:

• The Jena RDF materials from lecture 1:
  • The core RDF API (mandatory)
  • An introduction to RDF and the Jena RDF API (mandatory)

Useful materials:

• • Package org.apache.jena.rdf.model (supplementary, but necessary for the labs and project)

Lecture 3: SPARQL

Themes:

• Programming SPARQL and SPARQL Update in Jena

Useful materials:

• Javadoc for Apache Jena ARQ 3.2.0
  • Query, QueryFactory, QueryExecution, QueryExecutionFactory, ResultSet
  • UpdateFactory, UpdateAction

(supplementary, but perhaps necessary for the labs and project)

Lecture 4: Application Architecture

Mandatory readings:

• Apache architecture overview (mandatory, from lecture 1)
• Apache's TDB (mandatory)
• Apache's TDB Java API (mandatory)
• Apache Jena Fuseki (mandatory, we use Fuseki 2)

Useful materials:

• Package org.apache.jena.tdb Class TDBFactory (createDataset)

Lecture 5: RDFS

Themes:

• Programming RDFS in Jena

Useful materials:

• Reasoners and rules engines: Jena inference support (cursory; sections 1 and 3 are relevant, but quite hard)
• Javadoc for
  • Model (createRDFSModel)
  • InfModel (getRawModel, remove + the same methods as Model)
  • RDFS (label, comment, subClassOf, subPropertyOf, domain, range...)
  • Reasoner (but we will not use it directly)

(supplementary, but perhaps necessary for the labs and project)

Lecture 6: RDFS Plus

Themes:

• Programming basic OWL in Jena

Useful materials:

• Javadoc for
  • OntModel (createOntologyModel)
  • OntModelSpec (the different reasoners are outlined here (very long), OWL_MEM_RULE_INF is a good starting point)
  • OWL (defines built-in OWL resources)
  • OntClass, Individual, ObjectProperty, DatatypeProperty

(supplementary, but perhaps necessary for the labs and project)

Lecture 7 and 8: Vocabularies

Not directly programming related.

Lecture 9 and 10: Linked Data Resources

Not directly programming related.

Lecture 11 and 12: Web APIs

Themes:

• JSON, JSON-LD in Java

Useful materials:

• JSON-LD Java

Lecture 13: OWL

Themes:

• Programming advanced OWL in Java

Useful materials:

• Jena Ontology API (we will most likely not go into this) (cursory)

Lecture 14: OWL DL

Themes:

• Programming with OWL-DL reasoners in Java

Useful materials:

• See lecture 13

Lecture 15: Ontology Development and Evaluation

Not directly programming related.
