Status

• This working group is approved by Web3D Consortium Board of Directors.  Hooray, here we go!
• We have commenced weekly Working Group teleconferences on Thursdays following Design Printing Scanning calls.
• Results are reported on the x3d-public mailing list with members-only list semantics@web3D.org (subscribe)

Overview

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.

Motivations, Goals and Objectives

See the X3D Semantic Web Working Group Charter for our motivations, goals and objectives.

Outcomes

Many inter-related tasks are intended to achieve the following overall outcomes.

1. Create appropriate specifications and recommended practices for Semantic X3D.
2. Build suite of exemplars and tools exposed through various portals.
3. Publish X3D Ontology to deploy semantic queries and products based on multiple formats
   • RDF/OWL, Terse RDF Triple Language (Turtle) and JSON for Linking Data (JSON-LD).

Related Working Groups

Web3D working groups, portals and practices that are expected to inform, adopt and demonstrate this work include

• Design, printing and scanning: CAD modeling in all forms, feature recognition, and digital engineering.
  • Also work demonstrated by NIH 3D Print Exchange and X3D Model Exchange for Navy/Marine Makers.
• Heritage: archival publishing, natural history and cultural heritage exemplified by Born To Be 3D #B2B3D
• Humanoid Animation: documenting human models and animations
• Medical: electronic health records and diagnosis, especially HL7 FHIR standard for health care data exchange

Activities

1. Collect and assemble all relevant work related to X3D metadata and ontologies.
2. Collect links for relevant Semantic Web standards and approaches
3. Define a comprehensive set of use cases corresponding to Web3D Working Groups
4. Place notional use cases and actual examples in version control
5. Compare mappings for RDF/OWL in preceding work
6. Show autogeneration of RDF/OWL mappings through stylesheet adaption of X3D Unified Object Model (X3DUOM)
7. List and define addition heuristics that cannot be autogenerated
8. Determine whether mappings to other metadata standards are appropriate (e.g. MPEG-7)
9. Additional work is expected to emerge as semantic products develop and mature.
