2. Paper: we will adapt and refine the contents of both SemanticWeb.Pro presentation and IC3D paper/presentation for Web3D 2020 Conference, submitting a new 8-10 page conference paper.<br>
<br>
Last year we just had a workshop and not a paper, so having a full paper this year is appropriate. We want to encourage individuals working in 3D shape search/semantics to continue to great track record of success in the Web3D conferences.<br>
<br>
Jakub thinks that a special paper focus might be<br>
- evaluation of the X3D Ontology and XSLT transformation,<br>
- performance of transformation,<br>
- comparison of structural complexity, and<br>
- size of X3D knowledge bases and primary scenes<br>
<br>
Might anyone else be interested in submitting a semantics-related paper, perhaps we can organize a semantics session? We have 19 days.<br>

2. With some discussion, we think the following is the best approach for the URL/URI problem.<br>
<br>
PREFIX x3d: <<a href="http://www.web3d.org/specifications/x3d-4.0.xsd#" target="_blank" rel="noreferrer">http://www.web3d.org/specifications/x3d-4.0.xsd#</a>><br>
PREFIX x3do: <<a href="http://www.web3d.org/specifications/X3dOntology4.0#" target="_blank" rel="noreferrer">http://www.web3d.org/specifications/X3dOntology4.0#</a>><br>
<br>
Specifically:<br>
<br>
<a href="http://www.web3d.org/specifications/X3dOntology4.0" target="_blank" rel="noreferrer">http://www.web3d.org/specifications/X3dOntology4.0</a><br>
can map to actual file<br>
<a href="http://www.web3d.org/specifications/X3dOntology4.0.ttl" target="_blank" rel="noreferrer">http://www.web3d.org/specifications/X3dOntology4.0.ttl</a><br>
<br>
At a later time we might want to have alternative forms (e.g. XML or JSON-LD syntax) for this same ontology asset. Each variation can have a specific url address, but the x3do: prefix can refer to all of them equivalently (since they will indeed be equivalent).<br>
<br>
This makes sense and has no chance of inflicting any harm on prior work... We therefore will test this approach, Don will implement/deploy and then we can evaluate on our next group call. You will see all of the changes reflected throughout<br>
<br>
* X3D Ontology for Semantic Web<br>
<a href="https://www.web3d.org/x3d/content/semantics/semantics.html#" target="_blank" rel="noreferrer">https://www.web3d.org/x3d/content/semantics/semantics.html#</a><br>
<br>
* X3D Specifications: Schema and DOCTYPE Validation<br>
<a href="https://www.web3d.org/specifications" target="_blank" rel="noreferrer">https://www.web3d.org/specifications</a><br>
<br>
Once everything is in place, as a courtesy we will then ask for a website redirect for the prior (currently unlinked) URI.<br>

For next week, it is not clear if our schedules can align. We will try and will use email/phone otherwise.<br>
