Different time slot to accomodate participants interested in SSN.

Different time slot to accomodate participants interested in SSN.

Apologies. This meeting is cancelled. Please see public mailing list 1 with a request for what to do with your new spare hour.

Canceled due to Europe summer holidays

One hour later than usual, to allow members of the WoT WG to join.

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

Hello SDW-WGers ... Linda and I have decided to cancel this weeks plenary call. We have nothing specific on the agenda, and work continues elsewhere within the Best Practices sub-group. For next month (June), we plan to run a session in the OGC Members Meeting hosted in Madrid. Hope to see you there in person - but if not, then online. Best regards, Jeremy & Linda

Canceled because of holiday
