Comments sought on the Semantic Sensor Network (SSN) Ontology http://w3c.github.io/sdw/ssn/,

Dear all,

The Spatial Data on the Web Working group is trying to advance its current work on the Semantic Sensor Network (SSN) Ontology document, available at http://w3c.github.io/sdw/ssn/, through to formal W3C Recommendation.

The purpose of revisiting the original SSN ontology was to address the issue of its complexity, partly due to its layering underneath the Dolce-UltraLite upper level ontology. In response to this, the new Semantic Sensor Network ontology [1] offers several ontology subsets that are distinguished mainly through their ontological commitments. At its core, a new ontology is proposed, namely the Sensor, Observation, Sample, and Actuator (SOSA) ontology [2]. SOSA acts as a central building block for the SSN, but puts more emphasis on light-weight use and the ability to be used standalone, in particular, in a Web context providing an experience more related to Schema.org. It also introduces, as the name suggests, additional terms pertaining to Actuation, a concept of growing importance in the Web of Things and new terms around Sampling.

If you are a user of the original Semantic Sensor Network ontology [3] and/or are interested in using the new set of ontologies and wish to make comments on the revised version, your comments will be very welcome. Please send any comments to public-sdw-comments@w3.org<mailto:public-sdw-comments@w3.org?Subject=Re%3A%20OWL%20Time%20Ontology%20update&In-Reply-To=%3C042a8c93-ddea-50bc-2829-3328d69acf31%40w3.org%3E&References=%3C042a8c93-ddea-50bc-2829-3328d69acf31%40w3.org%3E> rather than this list.

The Working Group is short of time so the sooner comments are received the better.

Kind regards,
Armin
