Re: Metadata on sensor, actuator or sampler

Hi Dirk,

Thanks for your interest in the working group and your feedback!

There is a horizontal module that allows the modelling of some system capabilities http://w3c.github.io/sdw/ssn/#System-capabilities of Sensors and Actuators. However, some of the metadata attributes that you mention are the concern of the Thing description that the Web of Things working group is currently working on: https://w3c.github.io/wot-thing-description/ We are trying to make sure that the metadata on that lower level is aligned with the more abstract metadata descriptions in SSN/SOSA.

Hope that answers your question.

Kind regards,
Armin

Hi SDW – SSN,

I have been following the SSN developments for the last couple of months and I have not found much on metadata of the actual sensor. Contrary to O&M and ISO19115 which is metadata on the observations or measurements, I mean the metadata on a physical sensor, actuator or sampler. For example as is done in SensorML, see: http://www.sensorml.com/sensorML-2.0/examples/metadata.html. This could be metadata such as: name of the sensor, type, manufacturer, electrical requirements, start time, or measurement properties. Has any work been done on aligning SOSA to SWE / SensorML, or are there other options to link to metadata of a sensor, actuator or sampler?

Any insight is greatly appreciated.



Kind regards,
