RE: Question on roadway weather event standards

George,

The WMO BUFR (and others such as GRIB, CREX, …) controlled vocabularies, as well as being ‘on paper’ in six languages, are also in managed registers at https://codes.wmo.int/ .

There are several thousand terms defined, and there is some more work to be done, but this has been delayed by a major restructuring of WMO. The terms include some that are agreed jointly with the aviation industry, through ICAO.

HTH, Chris

Hi,

It might also be worth having a look at the ATM Information Reference Model (AIRM). The AIRM provides the reference vocabulary for defining air traffic management information, and Meteorology is one of the subject that is covered by the AIRM. The complete AIRM vocabulary is modelled in UML and the derivation of OWL/RDF ontologies from that UML reference has been explored already.

You can find more information at this link : http://airm.aero/

WMO BUFR is a well established standard for reporting stationary weather station data.  It is very efficient set of codes as it was designed to meet very low bandwidth.  It is used operationally around the globe for reporting mandated by WMO.

BUFR may well suit requirements here, unless there is a need for web based ontology or if the weather observation is associated with a moving platform.  In which case the BUFR codes are a useful stating place may not meet those requirements.

Im not suggesting WXXM directly fits the requirements either; it quite possibly is too much.  But it does have its basis in an Web friendly ontology for observations and measurements and it does provide weather for moving objects.

NTCIP 1204 was developed largely based on WMO BUFR and I believe we still have many references to the BUFR codes within the standard. I believe this standard is used for virtually all modern deployments of roadside weather stations in the US and in many other countries. While the data is not presented as an “ontology”, it is defined as an SNMP MIB within the standard and inferring the ontology is a fairly straight forward process from there.

I am happy to convert this into a formal ontology, but this raises two important questions:
1. What conventions should we use to document the ontology?
2. How do we manage the copyright on the generated material?

I propose the following answers:
1. I believe we need both a formal documentation language (e.g., OWL) as well as a graphical notation to facilitate human consumption. Assuming we use OWL as the formal language, I would suggest the Ontology Definition MetaModel (ODM) provides a reasonable graphical equivalence, but I find a few of its notations rather cumbersome and unnecessarily space consuming. I am happy to consider alternatives, but I think one of our first priorities should be to decide on how we will convey the model and we should strive to be as consistent as possible.

2. The nature of a large scale ontology is that there will be many, many experts that need to contribute their information to the ontology. IMHO, it is unreasonable to assume that any one standards development organization (SDO) will really own this ontology, it should be considered a public resource. From that perspective, I propose that it be permanently hosted on a public Github site and we establish rules on how we (i.e., multiple SDOs) formalize and approve content  into the “approved” branch. If the effort is to become successful, we have to have buy-in from a large community and the only way that will happen is if they all believe they have a sense of ownership and input into the final product.

Ted,

You are correct that OGC, TC211 and W3C have observation and measurement ontologies.  Development of roadway weather observations would do well to use those mature standards as they have been deployed around the globe in sensor webs.   Unfortunately, I am not aware of an existing ontology for roadway weather observations.

An ontology for roadway weather observations could review the aviation weather information models, e.g.., the WXXM standards for aviation weather developed by WMO and ICAO/FAA/EUROCONTROL using ISO/OGC standards.  The aviation Weather Information Exchange Models standards could be an input to a road surface moving vehicle weather event that included Observations and Measurements.

Weather Information Exchange Models
The Weather Information Exchange Model specifications support the data-centric environment. It supports MET information collection, dissemination and transformation throughout the data chain. The 3-tiered model (WXCM-WXXM-WXXS) is referred to as a single entity, the term used is 'WXXM'.

   RJ,

   George or Clemens,

   OGC and TC211 both have observations ontologies. Roadway weather
   event/conditions may be served with combination of the route
ontology
   Clemens is working on, observations over time (TimeseriesML) and
NTCIP
   1204. That would follow a core/modular approach over monolithic.

Hi RJ,
To comment from the ISO JTC1 side of things - we don't
currently
have weather conditions in our ontology, but that was
definitely an
item that we had marked for future work. Would definitely be
interested in seeing  the model that Volpe is working on, as
well
as if other groups have addressed this. As Ted mentioned,
maybe
this might be a good question to post to the new mailing

   Adding some specific people to this message to see if

   What sort of data models exist, under development or

There is

Some

ITS
   second. I have had some access inside OGC plus

   I'm starting to form a cross standards body
