5.1 *Working group assets*
The X3D Semantic Web Working Group is a Web3D Consortium member-only group that does most of its business openly on the x3d-public mailing list.

"The X3D Semantic Web Working Group mission is to publish models to the Web using X3D in order to best gain Web interoperability and enable intelligent 3D applications, feature-based 3D model querying, and reasoning over 3D scenes."

5.2 Event: *Semantic 3D 2019 Workshop*
First Eurographics-EuroVR Workshop on Semantic 3D Content
http://semantic3d.org/workshop
Submissions for papers, posters and demonstrations are now requested.
"The 1st Eurographics-EuroVR Workshop on Semantic 3D Content (Semantic 3D 2019), sponsored by the EuroVR Association, will address an extensive range of research, development, and practice related to the use of the semantic web for representation, creation, visualization and maintenance of 3D content and animations. The goal of the workshop is to share innovative and creative ideas that enable development of semantic 3D applications for a wide range of 3D environments, including the web, mobile as well as virtual and augmented reality (VR & AR) setups.
Works related to various application domains, including e-commerce, education, cultural heritage, entertainment and infotainment, social media, tourism, medicine, military, industry and construction (and many others) are welcome. The approaches will be considered in the context of building scalable, pervasive 3D/VR/AR systems using different semantic web (e.g., RDF, RDFS and OWL) and rule-based standards, 3D formats and browsers. Finally, common fields of interest and opportunities of future collaboration will be identified and discussed.
The workshop attempts to foster and support the increasing development, use, and utility of semantic 3D technologies for researchers, application developers, domain experts as well as for end users. This includes semantic creation of interactive 3D content, robust and versatile semantic 3D content representation and delivery standards as well as semantic presentation and interaction techniques enabling development of user-friendly 3D/VR/AR applications.
The main topics of the workshop include, but are not limited to:
Ontologies for 3D and animation annotation, representation and retrieval
Semantic metadata for 3D and animation description
Ontologies based on 3D formats
Semantic 3D formats, including semantic X3D
Domain-specific ontologies for 3D description and representation
Semantic modeling and assembly of 3D content
Semantic methods and tools for on-demand, adaptive and contextual 3D visualization and generation
Semantic and contextual 3D/VR/AR web services
Semantic queries to 3D scenes and 3D content repositories
Semantics for immersive analytics in 3D
Semantic representation and modeling of 3D animations and interactions
Ontologies for multimodal interaction in VR/AR
Semantic representation and modeling of 3D content behavior
Explorable VR/AR applications and queryable behavior-rich VR/AR applications
Semantic 3D/VR/AR web applications
Semantic 3D graph annotations
Novel interactive semantic 3D applications in all areas and sectors, e.g., entertainment, education, training, cultural heritage, medicine, military, smart-manufacturing / industry 4.0, information visualization, scientific visualization, geo-visualization, building information modeling (BIM), and architecture."
The workshop is being help 6 May 2019 in Genova Italy as part of EuroGraphics 2019.
- Paper/poster/demonstration submission deadline: 3 March 2019
- Acceptance notification: 17 March 2019
- Camera-ready paper/poster/demonstration submission: 24 March 2019
- Early registration: 6 April 2019

5.3 Event: *Protege course"
Protégé Short Course - Stanford University
https://protege.stanford.edu/short-courses.php
"With more than 300,000 registered users, Protege is by far the most widely used ontology editing environment in the world. The Protege Shoulr Course offers a 3-day intensive training in use of the Protégé toolset, ontology development, and OWL.
We cover best practices in ontology building and the latest Semantic Web technologies, including OWL 2, RDF, SPARQL, and SWRL. The course includes lots of hands-on activities and we allow plenty of time for interaction with the instructors. We allocate time daily for you to work on your own projects, and to ask the Protégé team for advice and feedback. All instructors are Protégé staff members, so you will learn directly from the creators of the toolset."
TOPICS
* Steps in the ontology development process
* Semantic Web technologies, e.g. OWL, RDF, SPARQL, SWRL
* OWL 2 language, reasoning, and querying
* Ontology-driven application development
* Collaborative ontology development
* Lessons learned in real world projects
Protege is a free, open-source ontology editor and framework for building intelligent systems, written in Java that fully supports the latest OWL 2 Web Ontology Language and RDF specifications from the World Wide Web Consortium.
Protégé is supported by a strong community of academic, government, and corporate users, who use Protégé to build knowledge-based solutions in areas as diverse as biomedicine, e-commerce, and organizational modeling."

5.4 Related work: *X3D Metadata Simplification*
Several issues make X3D typed metadata a bit difficult to create and read. Discussion has resumed on x3d-public mailing list and in X3D Working on ways to provide improvements that work satisfactorily in all X3D file encodings and programming-language bindings.
[x3d-public] gltf metadata: X3Dv4 MetadataSet design issue
http://web3d.org/pipermail/x3d-public_web3d.org/2019-February/010020.html
[x3d-public] X3D meeting minutes 8 FEB 2019: X3Dv4 mantis github specification changes, glTF plans, MetadataSet
http://web3d.org/pipermail/x3d-public_web3d.org/2019-February/010048.html
However there is still resistance to modifying MetadataSet field "metadata" as MFNode, consolidating it with the "value" field for better simplicity and less likelihood of error for child nodes. The concerns are well placed but mostly theoretical since, to date, there is little (or no) known practice that argues against simplification.
We might need to look at a few metadata collection vocabularies for examples to understand this issue better, since it is likely to significantly influence use of semantic web constructs within X3D models that are further within HTML5.

5.5 Primary work: *slideset Semantic X3D - thoughts and ideas*
Much detailed architectural work is in progress, distilled here.

Interesting examples for topological relations using bounding-box values for Shape and grouping nodes: disjoint, touch, equal, within, contains, overlap, left, right, above, below, over, behind. Reference:

We went quite a bit further, including discussion of ontology bridging and mapping. Work continues.
Working together in Google Slides while simultaneously on Web3D teleconference is pretty powerful means to collaborate.
=================================================================
5.6 *Next meeting topics*
- adding links and resources to the Assets pages
- continue working on the slideset, clarifying common conceptual terms (even beyond spatial)
- consider implementation efforts.
Apologies for late publication of these notes, a lot is happening and there is plenty of room for others to get involved.
=================================================================
5.7 *Additional participation and improvements always welcome*
Web3D Consortium membership has value, recommend everyone consider supporting these open + protected efforts.

Having fun with X3D and Semantic Web! 8)
