External namespaces and terms
Most applications using VF will need terms defined in various other vocabularies. In fact, we consider these to be essential to a complete value flows core vocabulary. Below are the elements we are re-using from well established vocabularies (web ontologies).
- A list of units can also be found here. Each subclass on this page has an additional list of units.
- VF will use (at least)
om2:symbolas properties of Units.
- See note at the end of Flows regarding display of unit
Some useful constructs, others here: https://www.w3.org/TR/owl-time/#topology, see the Interval Relations.
vf defines property chain axioms for
vf:hasPointInTime as slight variant
of Alignment of PROV-O with OWL-Time.
