SOSA/SSN/Time experiences

Hi Simon and Chris,

Besides my modest role in supporting Spatial Data on the Web, I have a
more substantive one leading our Automotive standards effort.

At the center is a common data model for the information available
about a vehicle, static and dynamic coming from sensors. For in-vehicle 
use we've come up with a protocol and are using JSON but in the cloud
you won't be surprised to hear that we're using an ontology that
Eurecom (part of Institut Mines-Télécom) and BMW has come up with an
ontology. IMT has made a Member Submission [1] to enable standards
development.

Vehicle Signals Specification ontology (VSSo) is comprised of the
underlying common data model for vehicle signals (Vehicle Signals
Specification - VSS [2]), your SOSA/SSN and Time along with core
vehicle ontology [3] done a few years ago by a number of ontologists
operating in EDM Council/W3C Community Group [4]/[5]. Incidentally that
group is reconvening and will be working on a number of automotive
related ontologies to support broader range of uses.

We have refactored the underlying VSS, influenced by how we want to see
structural changes for use in the cloud, recently making a 2.0 release.
We will work on tooling to keep VSSo in sync with VSS developments and
are having some design discussions starting in github [6].

It occurred to me to setup a meeting with you to see if you can impart
any wisdom from your and perhaps others' use of SOSA/SSN and Time in
other ontologies that we might benefit from. We'd be interested in what
led to the extensions [7][8] and what else might be in consideration
for more. 

If you are inclined, I am thinking I should get up early one morning
EDT to not be too late into the evening in Australia and be reasonable
for Europe. Please propose some times, if necessary I can come up with
a Doodle.
