Joint SDW-WoT WG session

• Past
• Confirmed

Session objectives:
(a) Define the geolocation deliverables for next WoT WG charter (2023 onwards). A starting list is here [1]. Use cases will guide what kind of geolocation data we might need.
… Do we need velocity? Maybe, the use case is transportation or robotics.
… Do we need to identify topology? Maybe, if we are talking Building Information Management systems.
… Do we need to worry about visibility from given viewpoints? Maybe, if the use case is AR.
…
(b) Agree schedule for routine checkpoint joint sessions and date of next meeting. Ongoing coordination is needed to ensure that WoT leverage existing geospatial standards and avoid creating new - especially around vocabularies/ontologies.

WoT gaps and future work are listed here [2].

WoT WG view is that GeoPose (limited to orientation?) and GeoSPARQL (missing a wat to access actual geolocation data in a consistent way?) don't cover all the use cases.

Looking forward to seeing you. Jeremy and Linda
(SDW-WG co-chairs)

[1]: Geospatial deliverables may include the following

1. Geospatial discovery mechanisms (e.g. finding Things near a certain location)
2. Geospatial data encoding standards, for both metadata (Thing Descriptions) and dynamic data (here is a proposal, but it is only an outline): https://github.com/w3c/wot-discovery/blob/main/proposals/geolocation.md; may be necessary to enable 1.
3. Geospatial use cases (e.g. logistics, Smart City infrastructure management, etc.). We have a set of use cases here, https://github.com/w3c/wot-usecases, and recently did a review of gaps here, https://github.com/w3c/wot-usecases/blob/main/USE-CASES/coverage.csv, and it was clear that accounting for location is one of our biggest gaps.

[2]: Gaps and Future Work:
• GIS Integration
o Geospatial data and discovery
• Data Management
o Digital Twins and shadows
o Event notifications
o Historical data
• Security
o Key provisioning and onboarding
o Secure LAN access
o Proxy services
o Access control and ad-hoc sharing
o MUDS
• Accessibility
o Sensory modality mapping
o Textual/descriptive interfaces
o Service location
o Mobility services
• Advanced Use Cases
o Transportation
o Logistics
o Distributed energy management
o AR visualization
o Analytics integration e.g. for health and safety monitoring

Agenda

The meeting focuses on a discussion starter about how the SDW-WG and Web of Things WG might collaborate for WoT Geospatial

Agenda:

• Introduction of WoT Geospatial plans by Michael McCool
• Discussion
