Request to review new W3C Semantic Sensor Network (SSN) Ontology, http://w3c.github.io/sdw/ssn/

[da...@danhlephuoc.info]

Dear OpenIoT group members,

As I know OpenIoT uses old version of SSN[3] as a core ontology, hence,  its upcoming official W3C Recommendation might significantly effect your users and developers. On behalf of the SSN editor team, I would like to inform you the newest draft of SSN available to public review at http://w3c.github.io/sdw/ssn/. Please send any comments to public-sd...@w3.org rather than this list. 

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.    

Best regards,

Danh
