The revision of OWL Time subtly changed the semantics of how we model temporal extents.

We also rely on some custom data properties that make it difficult to apply temporal reasoning rules designed for use with OWL Time.

It would also be worthwhile to make it clear how PeriodO temporal extents relate to the fuzzy-bounded E2 Temporal Entity of the CIDOC CRM.

Finally, it might be nice to be able to express PeriodO temporal extents using EDTF via the EDTF Ontology.

For all these reasons we need to revisit the way temporal extents are modeled in PeriodO. Ideally any changes would

  1. not affect the JSON representation of the dataset (since the @context would change accordingly), and
  2. be backward-compatible with earlier RDF versions of the dataset.
