IoT and public datasets

[Dan Brickley]

Just a quick note to draw attention to a potential link between "Schema.org for IoT" and public datasets from sensors and measurements.

At Google we have some basic initial documentation up explaining our initial schema.org-based approach towards improving search for scientific datasets (where 'scientific' is broadly conceived and covers e.g. social science, open govt data, stats, geo etc.).

See https://developers.google.com/search/docs/data-types/datasets 

To explore further the IoT/dataset connection, I would love to find some good examples of published datasets that engage with the IoT world, e.g. open data from sensor networks and other kinds of measurement. Anyone care to dig deeper into this or have pointers to share?

cheers,

Dan

Hi Dan,

Yes, Ericsson could probably help with some of this and point to datasets that are available or help connect you to folks that have them.

1. A recent project that I know about already and mentioned to Max on the prior sdo-iot call is:

Ericsson has IoT devices anchored in the Chattahoochee River now with AT&T providing connectivity and the data is collected by the https://chattahoochee.org/water-quality/ whom you can contact directly for the public data.

More info about the project:

https://www.ericsson.com/news/160105-ericsson-and-att-team-up-on-connected-water-as-a-smart-sustainable-city-initiative-in-atlanta_244039856_c

2. There are probably a few European Agriculture Coalitions that have SOME data... will have to get some contacts for you.

3. and many Smart Cities already that might have data to provide. Example: https://www.ericsson.com/thinkingahead/the-networked-society-blog/2015/03/26/smart-cities-internet-things-meets-smart-digital-citizen/

Ericsson is involved significantly in so many areas of IoT, so I'm sure that could help point to some or give contact info.  Or just go on our own corporate website. starting here for IoT: https://www.ericsson.com/spotlight/services/

I'll ask around more tomorrow.

In UCSD,  we are going through copyright documentation for publishing a building data. It will include 5000 sensors' raw metadata and timeseries data. Also five buildings metadata from different campus are already available in https://github.com/BuildSysUniformMetadata/GroundTruth

Hi all,

I am going to share some endpoints and useful links about the OGC SensorThings API (wikipedia), an open geospatial standard for exchanging sensor observations.

In Calgary, we recently launched a citizen-based air quality monitoring pilot, called Smart Citizens for Smart Cities. Now we have 50+ sensors in Calgary monitoring PM2.5 continuously.  The data collected by the sensors are very nice.  What might particularly interest this group is that the data is available in OGC SensorThings API standard and the sensor observations are compliant to the OGC/ISO Observations and Measurement standard (ISO 19156:2011).  I am the editor of the OGC SensorThings API.

Here is the link to the API endpoint for the sensor observations.  If you are familiar with OASIS OData, you should know how to use it.

Calgary air quality:  http://example.sensorup.com/v1.0

Taiwan LASS (air quality too): http://13.72.99.57:8080/OGCSensorThings/v1.0 

There several other public air quality IoT systems using OGC SensorThings API to publish their observations, including one in Nijmegen (50+ nodes) and one in Taiwan (1000+ nodes).  

Here is an example front-end demo of the OGC SensorThings API:

http://calgary-air.sensorup.com/

Here is two example SDKs for accessing the OGC SensorThings API:

http://sdk.sensorup.com/sta-chart/examples/

http://arcgis-sta-lib.sensorup.com/

OGC SensorThings API is an open international standard from Open Geospatial Consortium. As far as I know there are six different server implementations (Java, GO, Node) and many more client implementations.  Multiple nations around the world is going to endorse the standard as one of the national standards to exchange IoT data.

Cheers,

Steve

Hi,

 

The FIWARE project has an open data portal, https://data.lab.fiware.org,  with many datasets which source are cities. Such Open Data Portal is based on CKAN, http://ckan.org/ :

 

On the other hand, we are working, together with the GSMA and other operators, in Connected Living Programme, IoT Big Data project, to produce harmonized schemas for different IoT-related domains (you can see that those schemas reuse many properties from schema.org)  

 

http://www.gsma.com/connectedliving/wp-content/uploads/2016/11/CLP.26-v1.0.pdf

 

that’s a complementary initiative to http://schema.fiware.org

 

At the same time, we, and other operators working on that project, are starting to offer harmonized real time data following the referred schemas and making it available through a harmonized API for getting access to data, FIWARE NGSIv2,

 

http://www.gsma.com/connectedliving/wp-content/uploads/2016/11/CLP.24-v1.0.pdf

 

For instance,

 

curl --header 'fiware-service:AirQuality' --header 'fiware-servicepath:/Spain/Barcelona' "http://130.206.83.68:1026/v2/entities/?options=keyValues&q=dateObserved>2016-11-16T23:59:00&attrs=dateObserved,measurand,stationCode" | python -mjson.tool

 

can provide harmonized real time air quality data from the city of Barcelona.

 

thanks, best
