[x3d-public] [Semantics] X3D Semantic Web agenda, 23 SEP 2019: new X3DOntologypage

[John Carlson]

I’d like to look at slides, but links like:


http://https//www.web3d.org/x3d/content/semantics/documentation/workshops/X3dSemanticWebWorkingGroupCollectedConcepts.2019July27.pdf

on this page:

https://www.web3d.org/x3d-semantic-web-public-assets

Don’t seem to be available???

The link below the above one, links to sourceforge and after digging around some, I found this (downloaded):

https://sourceforge.net/p/x3d/code/HEAD/tree/www.web3d.org/semantics/documentation/papers/X3dSemanticWebWorkingGroupCollectedConcepts.2019July27.pdf

I will forward this to Michael, thanks a bunch!

Sounds good...

Our workshop materials and slideset describe our plans.  There is still a lot of ground to cover to get there.  I expect that we'll likely be focused on X3D-centric scene graph queries for the rest of the year.  We have to become adept at our domain before we can most effectively align it with others.

Recommendation: let's craft use cases, then example SPARQL queries that illustrate them with X3D models.  The following book is great:

* Bob Ducharme, Learning SPARQL, second edition, OReilly Media, Sebastopol, 2013.
   http://www.learningsparql.com

Now maintaining a list of helpful books at

As is everyone.  Best is to look at other sources, see what patterns work well, then apply them to X3D models.

Highest recommendation:

* Leslie F. Sikos, Mastering Structured Data on the Semantic Web: from HTML5 Microdata to Linked Open Data, Apress Springer Science+Business Media, New York, 2015.
   https://www.apress.com/gp/book/9781484210505

Those are in the RDF1.1 vocabulary and covered in the Learning SPARQL book.
