We still have not received a reply from Web3D Communications Team about making this a public list.<br>
<br>
As a result we will begin copying x3d-public as a routine until that problem is addressed.<br>
<br>
We also have a long-pending and repeated website request to make our ontology IRI match the website IRI.<br>

3. *Review session*. We reviewed the many changes to ontology and related work.<br>
<br>
- email thread (multiple responses):<br>
<br>
<a href="http://web3d.org/mailman/private/semantics_web3d.org/2019-October/000121.html" rel="noreferrer" target="_blank">http://web3d.org/mailman/private/semantics_web3d.org/2019-October/000121.html</a><br>
<br>
- website:<br>
<br>
<a href="https://www.web3d.org/x3d/content/semantics/semantics.html" rel="noreferrer" target="_blank">https://www.web3d.org/x3d/content/semantics/semantics.html</a><br>
<br>
4. *XSLT*<br>
<br>
- We agreed on the naming convention, which allows tracing query results back to the original X3D model.<br>
<br>
- We discussed whether base IRI is required. In the HelloWorld.ttl initial example, it is marked<br>
<br>
@prefix : <<a href="https://www.web3d.org/semantics/scenes/X3dScene1#" rel="noreferrer" target="_blank">https://www.web3d.org/semantics/scenes/X3dScene1#</a>> .<br>
<br>
We might do something with the meta identifier (if it exists), e.g.<br>
<br>
<meta content='<a href="http://X3dGraphics.com/examples/X3dForWebAuthors/Chapter01TechnicalOverview/HelloWorld.x3d" rel="noreferrer" target="_blank">http://X3dGraphics.com/examples/X3dForWebAuthors/Chapter01TechnicalOverview/HelloWorld.x3d</a>' name='identifier'/><br>
<br>
becomes<br>
<br>
@prefix : <<a href="http://X3dGraphics.com/examples/X3dForWebAuthors/Chapter01TechnicalOverview/HelloWorld.ttl" rel="noreferrer" target="_blank">http://X3dGraphics.com/examples/X3dForWebAuthors/Chapter01TechnicalOverview/HelloWorld.ttl</a>> .<br>
<br>
which also matches the Web address where it will exist. This can be automated for all models in X3D Example Archives.<br>
<br>
We can have stylesheet switches that omits or overrides such a value, depending on the person/tool converting.<br>
<br>
Therefore, over the next week HelloWorld.ttl will change accordingly. Since it is in version control, we can always re-check prior versions.<br>
<br>
<a href="https://sourceforge.net/p/x3d/code/HEAD/tree/www.web3d.org/semantics/examples/HelloWorld.ttl" rel="noreferrer" target="_blank">https://sourceforge.net/p/x3d/code/HEAD/tree/www.web3d.org/semantics/examples/HelloWorld.ttl</a><br>
<br>
This is a good goal for next week. Additional requests welcome, we can always add TODO items!<br>
<br>
--------------<br>
<br>
5. *X3D Ontology*<br>
<br>
There has been some work in using XML (e.g. .x3d) directly with RDF/OWL but we are deferring any such activity.<br>
<br>
TODO: there were a few links posted to the <a href="mailto:semantics@web3d.org" target="_blank">semantics@web3d.org</a> list - some from TEI Crete - we will collect links for them for future consideration. We will do this by email.<br>
<br>
Review points:<br>
a. removed ontology references to X3D XML Schema<br>
b. Since there is no information present in default values for fields, they will not be included in generated knowledge base like HelloWorld.ttl<br>
c. Default-value information is available in the X3D XML Schema, X3D XML DTD, and X3D Unified Object Model (X3DUOM).<br>
d. TODO: should we somehow include default values in the ontology, so that queries to determine if value is non-default? Not clear, Jakub will look further whether it is possible and practical.<br>
<br>
e. Confirmed that owl:unionOf constructs are now working correctly, without warnings.<br>
<br>
f. Jakub noted that we should consistently use "a" when stating "rdf:type" - will fix.<br>
<br>
g. We discussed how some fields (e.g. 'translation') do not have a common object-model basis.<br>
<br>
TODO: Jakub will post a screenshot in response to minutes... I will find the autogeneration diagnostic that links these.<br>
<br>
Corrected OWLDoc link:<br>

<br>
Thanks for the quick review! Continuing shared improvement is welcome.<br>

6. *Next Meeting*. We agreed to continue meeting for one hour each week.<br>
<br>
Wow, very productive. Have fun with X3D Semantic Web! 8)<br>

all the best, Don<br>
