Define and implement a mechanism for generating meta-data triplets

[omishali]

• You should define a general & convenient mechanism for generating meta-data triplets. Using fluent API for that purpose is definitely an option (but not the only option).
• At this stage, you should only generate triplets required for the meta-data (classes, properties) relevant for the stories of the current week.
• All meta-data triplets should reside in a single file called jbsOntology.ttl.

Before you start the implementation, send Oren a brief example of the two options:

1. Json input that defines the ontology
2. Fluent API.

Examples for the above requirement:

Json input that defines the ontology: see almost complete example at master/input/ontologies/jbsOntology/jbsOntology.json. the user can create an ontology ttl file in few simple steps:

1. define the ontology json
2. add to the master/src/generators/config.json the ontology.json file path (under the ontologyGenerator)
3. run
4. the output file will be created at output directory. NOTE: our tool already supports this flow.

FluentAPI: basically there are two options:

1. using the same triplet API but also create a namespace for the ontology. sample of code will look like that: Triplet.addNSprefix("jbo", "http://jbs.technion.ac.il/ontology/"); String classes[] = {"Sefer", "Perek", "Pasuk", "Perush", "Mishnaya", "Halacha", "Mitzva", "Seder", "DafGmara", "Masechet"}; for (String strVal : classes) { Triplet .triplet() .subject(strVal) .predicate(RDF_P_TYPE) .object(OWL_C_CLASS); Triplet .triplet() .subject(strVal) .predicate(RDFS_P_LABEL) .object(strVal); } currently we support that API too.

2. create a spacial API for ontology: a sample of code will look like this: String classes[] = {"Sefer", "Perek", "Pasuk", "Perush", "Mishnaya", "Halacha", "Mitzva", "Seder", "DafGmara", "Masechet"}; for (String strVal : classes) { OntAPI .ontology() .class(strVal) .label(strVal) .subClassOf(OWL_THING) }

Good job. We will discuss it during the meeting.
