RE: Recap Toulouse face to face

Two more things I wanted to mention....

Routing ad hoc
This was an ad hoc meeting with the W3C on transportation topics, which covered a broad spectrum of topics associated with information systems in vehicles. Ted Guild of W3C provided an overview of W3C activities in standards for transportation. Eurecom and BMW presented on the W3C Vehicle Information Service Specification, a WebSocket-based API for vehicle signals. Clemens Portele of interactive instruments detailed some of the results from the OGC Open Routing API Pilot. Finally, George Percivall, OGC's CTO led a discussion of emerging technology trends in Connected Autonomous Vehicles (CAVs), including the relevance of the OpenDrive specification.

There is an opportunity for W3C and OGC to collaborate on a Routing ontology; I created a Proposal in the SDW github Proposals project for this [6].

GeoSemantics DWG
After receiving some recent change requests for GeoSPARQL and the OWL Space project proposal, the GeoSemantics DWG is working on a White Paper on the benefits and challenges of geospatial graph data. This paper has two purposes. Firstly, to describe the benefits of representing geospatial data using semantics and graph technologies. Secondly, to outline some shortcomings of the existing GeoSPARQL implementation specification that, if addressed, would unlock its potential to a greater extent. The shortcomings described are in large part taken from existing change requests for and extensions of GeoSPARQL. People from outside OGC are welcome to participate and already do, e.g. members of the W3C Linked Building Community group and the ISO group working on Graph Query Language.

Joseph Abhayaratna is leading this work and is organizing a telco about it in the near future. @Jo, once you've settled on a date, would you inform the SDWIG members about it as well?

The GeoSemantics DWG will also seek to be involved, in a reviewing capacity, in the ISO group working on Graph Query Language (GQL).

Onderwerp: Recap Toulouse face to face

Hi all,

Here's a short recap of the face to face meeting we had in Toulouse at the OGC TC.

SSN extension
Simon Cox presented the latest Editor's draft of the SSN Extensions document [1]. The idea is to publish a new WD of this document (which is intended to be a W3C Note / OGC Discussion paper). He has asked the group for review [2] Ted Guild will help navigate this through the process once the group agrees to publish this as a new WD. The new 'evergreen' standards process of W3C may be applicable.

WebVMT
Rob Smith gave an update on the WebVMT work. It's still in incubation phase, partly within the Web Platform Incubator Community Group. Contact with browser developers has been initiated, revealing that there has been previous work on video geotagging but at the time no consensus was reached. There seems to be some interest in doing this now.

MapML
The community around MapML is slowly developing; Peter Rushforth did some community building at TPAC this year and talked to browser developers from Agalia, Beaucoup, Firefox, Chrome. There is also a draft use cases & requirements document [3]. On the OGC side MapML is being worked on in testbed 15. Peter and Ted will look into organizing a W3C workshop on maps in HTML.

Discussion on charter
The general feeling about the proposed charter is positive; those present agreed we should move this charter forward. There were some pointers to improve the text. The chairs will transfer the charter text to the right template and further improve the text. When rechartering we may want to think about promoting the group some, in order to remind the W3C and OGC membership what we're doing.

Linked building data
Mathias Bonduel and others from the Linked building data community group joined to present their work. They are working on ontologies for linked building data, collecting use cases, requirements, developing best practices and ontologies, in the future planning to evolve to a W3C WG. They are contacting the SDWIG to see if OGC can help with their use cases related to geometry and topology. This turns out to be related to the OWL Space / GeoSPARQL 2.0 work, currently discussed in the OGC Geosemantics working group, which they were invited to join. Another potentially interesting OGC standard is IndoorGML which describes topology of buildings.

SDW Finland
Esa Tiainen presented remotely [4] on low hanging fruit and how to move forward with spatial data on the web.

OGC technology trends
George Percivall presented the tech trends [5] OGC has their eye on and asks the group if there are more trends to record within the spatial web data trend group.
