Mapping of at-voc:timeperiod to the OWL Time Ontology

[cristianvasquez]

Currently, epo:Period and epo:Duration are described using different constructs. Specifically, epo:Period utilizes at-voc:timeperiod, which has a predefined set of values.

Below is a diagram illustrating how epo:Period and epo:Duration are used:

As mentioned in Issue #529, the OWL Time Ontology was proposed to describe epo:Period, aligning how time will be represented within the eProcurement Ontology (ePO). To support the analysis and the RDF materialization, we need to explore how at-voc:timeperiod can be represented using the OWL Time Ontology.

Question:

• Can all elements of at-voc:timeperiod be mapped using the OWL Time Ontology?

This mapping effort will also support ongoing work, such as Issue #40.

Proposed Output:

• A table mapping at-voc:timeperiod to corresponding representations in the OWL Time Ontology.
• Alternatively, an extension of at-voc:timeperiod so that its elements are also time:TemporalEntity.
