[x3d-public] [Semantics] X3D Semantic Web Working Group 14 MAR 2019: structural and conceptual semantics, semantic mapping MINUTES

[Brutzman, Donald (Don) (CIV)]

[cc: x3d-public]

Jakub and Thanos, thanks for proceeding with the meeting and helpful minutes on 14 MAR 2019.

We had a bit of a mixup last week, I'm afraid... USA had already shifted to Standard Time.  California is now UTC-7.

One hour prior to you two meeting, Christophe Mouton, Nicholas Polys and I had an interesting discussion about the X3D Semantic Web group's work. This line of thought led to sharing the SC4 STEP ontology presentation you saw.  Apologies for missed coordination - you are always welcome to call my cell if there is some mismatch in expectations we might quickly resolve.

We discussed "Coordination of Geometry and Topology Ontology Efforts", which addresses topics interesting to our group. We also discussed the stack of ontologies on slide 13 in our main presentation:

We extended the presentation with the concept of instances of the ontology stack (slide 14). Instances of the ontologies (T-Boxes) are knowledge bases (A-Boxes) representing particular 3D scenes and objects as well as other ontologies (T-Boxes) extending classes and properties from the stack. The main question (still open) is whether the instances of the mapping ontology should relate to a particular domain or not. Maybe, they should only link domain classes and properties to 3D-specific classes and properties (e.g., in the 3D Ontology).

As you each later noted, no meeting today... I must send regrets for next week, will be at Stanford University taking a 3-day course on open-source Protege tool for Semantic Web modeling - RDF, OWL, verification, reasoning, etc.

The suggested ontology-stack representation example looks like an interesting next step to pursue.

I hope that over the next two weeks we can also consider how the EuroGraphics and Web3D conference workshops can best proceed.  Good luck with your important work.

all the best, Don
