[semantics-public] [x3d-public] X3D Semantic Web 30 MAR 2020:OWL-Time considerations for X3D Ontology and animation mappings

[Joseph D Williams]

➢ However, it is not obvious how to derive it from an X3D document, which describes the primary state of a scene.

In x3d things that are static are defined by geometry and things that are not static are described by animation routines such an interpolators so the x3d document describes both the static and dynamic states exactly to any reasonable time slice.

Chaotic time, stochastic time, hypertime, quantum time, ordered time, disordered time.

Are we presenting as a united front or individuals?

This definitely is a rabbit hole, Alice.

The OWL-Time ontology could be used to represent fluents - temporal properties, which change over time and have different values at particular point or within particular intervals. The representation of linked objects by time slices with time points and intervals enables reasoning and queries. However, it is not obvious how to derive it from an X3D document, which describes the primary state of a scene.

=============================================
Wiktionary: fluent

https://en.wiktionary.org/wiki/fluent#English

1. That flows; flowing, liquid.

     fluent handwriting

2. (linguistics) Able to use a language accurately, rapidly, and confidently – in a flowing way.

     She's fluent in French.

all the best, Don
