> IoT Semantic Interoperability Workshop
> Background
> With the expansion of the Internet of Things (IoT), interoperability
> becomes more and more important. Standards-developing organizations have
> done a tremendous amount of work to standardize protocols to simplify
> implementation and to lower the cost of IoT products. As a result, new
> protocols were developed, existing protocols were combined in new ways,
> and lightweight profiles were defined.
> At the application layer, interoperability is not yet mature; the work
> on data formats (in the form of data models and information models) has
> not seen the same level of consistency throughout various
> standardization groups. Examples of standardization efforts in this area
> include the work by IPSO on their Starter Pack, the Cluster Library
> developed by the Zigbee Alliance, the OMA LWM2M, or the UPnP Management
> and Control:1 specifications.
> One common problem is the lack of an encoding-independent
> standardization of the information, the so-called information model.
> Another problem is the strong relationship with the underlying
> communication architecture, such as an RPC or a RESTful design.
> Furthermore, different groups develop similar concepts that only differ
> slightly, leading to interoperability problems. Finally, some groups
> favor different encodings for use with various application layer
> protocols.
> This raises a number of questions:
> - What is the state of the art in data and information models? What
>  should an information model look like?
> - What is the role of formal languages, such as schema languages, in
>  describing information and data models?
> - What is the role of metadata, which is attached to data to make it
>  self-describing?
> - How can we achieve interoperability when different organizations,
>  companies and individuals develop extensions?
> - What is the experience with interworking various data models developed
>  from different groups, or with data models that evolved over time?
> - What functionality should online repositories for sharing schemas
>  have?
> - How can existing data models be mapped against each other to offer
>  interworking?
> - Is there room for harmonization, or are the use cases of different
>  groups and organizations so unique that there is no possibility for
>  cooperation?
> - How can organizations better work together to increase awareness and
>  information sharing?
> (A discussion about the difference between information and data models
> can be found in RFC 3444.)
> Workshop Style
> The workshop?s main focus will be on discussing the harmonization of
> information and data models for use with IoT deployments. In order to
> keep the group at a manageable size, prospective participants are
> required to submit a position paper as an expression of interest. We
> will invite the authors of accepted position papers to attend the
> workshop.
> The workshop will be structured as a series of working sessions
> punctuated by invited speakers, who will present on-going
> standardization and research developments. The organizing committee may
> ask submitters of particularly salient papers to present their ideas and
> experiences at the workshop. We expect active participation of all
> guests.
