Agenda: https://www.w3.org/auto/wg/wiki/Auto-f2f-mar-2020
Clemens: unless Linda appears, I can give an overview of Spatial Data on the Web Best Practices
Clemens: maybe a brief overview
of OGC, Open Geospatial Consortium mix of companies,
universities, governments
... works with ISO TC211 Geospatial
...2014 joint
workshop to discuss how geospatial standards could be improved
(broader access): OGC W3C joint working group
Clemens: in 2014 started to run
into need to develop standards for the web and came together
with W3C to form SDWIG
...key output:
spatial data on the web best practices
...complimentary to W3C's "data on the web best practices" with
specific things for spatial data
Mark: some various OGC players keep us in SmartCities appraised of their work
Clement: routing APIs attempt at implementing some of the best practices
Ted: idea of
this session ...everyone understand where we're coming from,
come to an agreement on the vision of how the ontologies should
be architected
...how to
start organizing and structuring this
Ken: smart cities, ITS, OGC
Ted: accessibility representatives may be looped in later
...accessibility-aware engineers...W3C web accessibility initiativeTed: review of different groups' perspectives...next steps - agreeing on how things should be structured
Linda:
GeoSPARQL contains a small ontology for representation of
locations and geometries
...SSN
ontology via spatial data on the web working group
...SSN modular
structure: SOSA core, simple taxonomy; SSN more extensive
axioms...
...Routing
work that will be covered tomorrow; OGC setting up standards
working group for routing; draft charter (not publicly
available)
...purpose is
to develop and maintain a routing conceptual model, a routing
ontology, and a route exchange model, and to develop and
maintain an OGC API about open routing and maybe extensions to
the API
...ontology
work not certain, mostly focused on API and exchange model
Clement: will
be talking about some of this tomorrow...there are 2 general
groups: one with a focus on ontologies and the semantic web,
the other more focused on web APIs, json stuff, where semantics
don't play as much of a role
...routing
work so far not so much on the ontology end
...need to see
what other groups are doing and how we can reduce overlap and
make it fit together
Linda:
GeoSPARQL has been around for a while; used and implemented but
not a huge success; but there are now more and more change
requests coming in to OGC; implementers now who are interested
in developing it further and working on it
...looking
into maybe creating a working group for that in the future
...if it's of
interest it may be good to coordinate
Ken: what is
our actual goal? to start developing an ontology with a vehicle
focus?
...need to
consider 3 big things: (1) how do we govern development of the
ontology? (2) how does our ontology relate to other work? data
on the web, applications, APIs, (3) how do we actually document
it?
...once we
have those parameters in mind, then we can start delegating the
workload to different groups
Linda: which
other ontologies will we have some relationship with?
...SSN,
GeoSPARQL
Clemens: owl time
Ken: OGC observations and measurements abstract specification
Clement: a
precursor of SOSA
...revision
ongoing to bring it closer with SOSA and SSN
...UML model
vs SSN/SOSA owl models
Ken: start documenting what's out there
Clemens: start small and see if it gets picked up and you can extend it
Ken: agree;
aware of multiple different independent groups that are
interested in this topic
...group in
TC204 interested in parking
Clemens: risk of underlying repository is different groups use different language
Ken:...need to abstract things into a format that clearly maps one representation to another
Clemens: need clear mechanisms so as not to block other activities
Ken: do we agree that we need to establish the three baseline requirements?
Megan and Clemens agree
Ken:
presentation
...ITS data
model framework
...need for
combined top-down and bottom-up approach
...smart city
proposal, aligned with structure proposed by ISO JTC1 WG 11
(smart cities): custom, cooperative and core components
...3d view of
the intersection of the models
...propose use
of GitHub to facilitate coordination
<Ken> Ken to send slides to Ted
thanks
<Ken> We need to pick a small topic to investigate
<Ken> What are the scope of comments that we need to be looking at? (from Megan)
<Ken> ... We need to coordinate and identify all of the overlaps
discussion about use of GitHub, openness and ISO acceptance of approach
Carlos: how would you propose to select a small scope to begin with?
Ken: suggest
(from the ITS side) to start with one service package
...from the
architecture
