The IPSO Alliance will be represented at the upcoming Workshop on IoT Semantic/Hypermedia Interoperability, a program created to explore the role of hypermedia and/or semantic interoperability for reducing setup overhead and thus TCO, and, more generally, enabling interoperation in the first place.
- For example, OMA and IPSO smart objects use the LWM2M object model, which defines a set of pre-structured URI templates and registry of object identifiers with semantics attached. This provides machine-readable representations of the semantics, but self-description is not being used much.
- OCF has a hypermedia approach with discovery using /oic/res etc., which relies on self-description via pointing to predefined resource types and interface types, which in turn use a number of specification techniques, including JSON schema and RAML.
- There is also iot.schema.org, which will allow us to gather further semantic interoperability information in potentially a more granular way.
- W3C WoT cares a lot about self-description, with an RDF-based take on semantics and describing things.
- T2TRG cares about pulling all this together.
On July 15, we will have a workshop that includes people from these organizations/groups. The focus will be on building a landscape that can benefit from the various approaches, without necessarily papering over all the holes or filling in all the rifts. On July 16, we will have additional time for follow-on workgroups that want to make progress on specific issues.
