Carsten,

I would love to participate to discuss the data modeling aspects.
However, the IETF hackathon and its code take precedence.

Regards, Benoit

>> One of the interesting questions in the IoT space is 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 <http://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 work groups that want to make 
>> progress on specific issues.
>>
>> The venue is the Prague Hilton, the same hotel that will host IETF99 
>> directly after that. To further minimize travel, we chose the weekend 
>> directly after the July W3C WoT meeting in close by Düsseldorf.
>>
>> Elements of the agenda:
>>
>> State of the union
>>
>> We will have "state of the union" talks from each of the 
>> organizations, discussing from a personal perspective where we are on 
>> interoperability in the organization and what are the next steps.
>>
>> Research contributions, prototypes
>>
>> We will issue a call for contributions, with a goal of getting new 
>> views and new voices into the mix. This will be research on the 
>> approaches available for building hybrid, overarching systems, as 
>> well as some practical systems that are already demonstrating how 
>> this could be made to work in practice, such as systems for 
>> converting some of the formal notations and/or self descriptions into 
>> each other.
>>
>> Specific topics
>>
>> The below topics (and any other that come up) could be discussed on 
>> Saturday and/or result in more detailed breakouts on Sunday.
>>
>> Interops
>>
>> The "device ecosystem" oriented SDOs are now increasingly using 
>> common protocols and formats (CBOR, CoAP, IPv6) which is creating one 
>> narrow waist in the system, and we can look into creating a narrow 
>> waist also around semantic interoperability and hypermedia design 
>> patterns. Ultimately, it should not matter which device ecosystem(s) 
>> you use for your application. The device ecosystems can maintain 
>> their focus on intra-op and certification while an over arching 
>> web-like layer of interoperability can add more value to all of them.
>>
>> Now is a good time to start to organize cross-ecosystem interops, 
>> where we attempt to orchestrate devices and sources from these 
>> different device ecosystems. At this point we need to consider 
>> orchestration across applications as well as device to device 
>> interoperability.
>>
>> We have also discussed a lot about conducting more of the actual 
>> testing over the Internet. This seems like a good concept to build in 
>> from the beginning. What are the tools we need to conduct an online 
>> hyper-semantic interop series? Is it staged, from basic to more 
>> sophisticated?
>>
>> This seems to represent the canonical use case for both W3C WoT and 
>> iot.schema.org <http://iot.schema.org>;, as well as the various 
>> translators and bridges being created.
>>
>> Hypermedia forms
>>
>> HTML has a form element that can be used to construct POST request 
>> bodies (and other request payloads, such as for PATCH). An M2M 
>> equivalent has been lacking for quite some time, although there are 
>> proposals. Now that we have FETCH and PATCH (RFC 8132), the need is 
>> even more pronounced. What are the next steps towards common 
>> Hypermedia "forms", which would help at least T2TRG, OCF, and WoT?
>>
>> Hypermedia-driven applications in general
>>
>> T2TRG has a number of drafts documenting how application developers 
>> use hypermedia to aid in building thing-to-thing (and thing-to-cloud) 
>> systems. Are these complete? What else do we know about that? What 
>> about documents from, say, W3C or IPSO?
>>
>> Model translation
>>
>> We now have multiple proposals for data modeling (YANG, CDDL, JSON 
>> Schema, JSON Content Rules) as well as ad-hoc metamodels. What are 
>> the semantic powers of these modeling approaches? Can we 
>> automatically translate between them so we can make models of one 
>> ecosystem available for the other ones? How do we tap hidden Gems 
>> such as the ZigBee Cluster Library or the Bluetooth GATT specs? What 
>> about interaction modeling (also YANG, RAML, Swagger, ...)?
