Simulate BSBM generator

[mhoangvslev]

As of now, WatDiv is not capable of generating BSBM dataset, as defined by BSBM specification. The missing features are listed below:

• [x] Language tags for literal of type string. Language tags follow some discrete distribution.
• [x] Literal of type country. The literals follow some discrete distribution.
• [x] Export federated dataset.
• [x] Control for Left Hand Side term in relationships of type Many to Many or Many to One.
• [x] Type assertion triple/quads.
• [x] Control length of strings
• [x] Constraint dates according to BSBM Specs

Advantages

• Considerable faster generation time (3 days -> 30 minutes)
• No need for pre-processing and post-processing off .nq generated by the original WatDiv
• Closer to BSBM specifications

Disadvantages:

• WatDiv is no longer generic, i.e, every fine-grained constraints have to be hardcoded in WatDiv. Note: there is a generic strip-down version of WatDiv on my repo.
