Re: Semantics in the Web of Things

Hi Kristian,

I afraid we need to start from 100 steps behind.

How many IoT products are designed uponwell-defined type system?

e.g.
  "sensor_data: {temperature: 38}"

is this hot or cold? :-) I guess U.S. people think it's cold. I personally think it's extremely hot.

Personally, I'm working on EXI to introduce well-typed values (e.g. tagged by schema-defined elements). And SEP2 devices (IEEE21451.5) are using EXI and well-defined schemas, so I think that is a step towards 'semantic IoT'.

Regaqrds,

Such a stunning number of highly distributed heterogeneous devices will need to be interconnected and communicate in different scenarios anonymously. This implies that providing interoperability among "Things" on the IoT is one of the most fundamental requirements to support object addressing, tracking, and discovery as well as information representation, storage, and exchange. The suite of technologies developed in the Semantic Web, such as ontologies, semantic annotation, Linked Data, and semantic Web services can be uses as principle solutions for the purpose of realizing the IoT."/* -- Semantics for the Internet of Things: early progress and back to the future, Section 2 <http://knoesis.org/library/download/IJSWIS_SemIoT.pdf>
