Hello Dave,

If there is not a compelling reason to do otherwise, I would prefer not to open another use-case document, but rather to merge any additionally needed use cases into the existing one.
Even better would IMHO be to (also) map the requirements you mention below to one or several of the existing use cases, as it’s underlining the real-life relevance.

We have a document that is planned to be a use case deliverable, which is modified through the xml file at [1], resulting in the page [2].
We also still have the collection of contributed use cases in the wiki at [3], where we unfortunately did not yet have much progress in merging those use cases into the above-mentioned doc.

Best regards,

Thanks. It sounds like we need a broader range of use cases that would allow us to cover a broader range of metadata requirements, as listed on slide 20 of http://www.w3.org/2015/05/wot-framework.pdf and repeated below:

● Thing descriptions

          • Data models & relationships between things
          • Dependencies and version management
          • Discovery and provisioning
          • Bindings to APIs and protocols
● Security related metadata
          • Security practices
          • Mutual authentication
          • Access control
          • Terms & conditions, and relationship to liability
          • Payments
          • Trust and Identity Verification
          • Privacy and Provenance
          • Resilience
● Communication related metadata
          • Protocols and ports
          • Data formats & encodings
          • Multiplexing and buffering of data
          • Efficient use of protocols
          • Devices which sleep most of the time

What is the best way to proceed?  We could just start to document this as part of the IG Note on the Web of Things Framework starting with an outline in GitHub and revising it through the GitHub issue tracking mechanism.

p.s. I wonder if I am the only one who keeps forgetting the TF-?? abbreviations?

Best regards,

Dear Dave,

In the TF-DI we decided to stick to the use cases already contributed and listed in WoT wiki. I am trying to further analyse them to see if they have the need for comm. metadata. Perhaps by the next meeting I can give you a better answer.


Quoting Dave Raggett <dsr@w3.org<mailto:dsr@w3.org>>:

Hi Soumya,

My regrets as I will be meeting with the Open Group in Reading UK at  that time.

Do we have use cases that stress the need for communications  metadata?  For instance, imagine an electrocardiograph where you  need to log the waveform from several sensors.  In such cases, the  data is sent in blocks rather than as single values.

I am also interested in use cases where the sensors/actuators spend  most of their time asleep to conserve battery life, and as such can  only receive instructions at certain times. There are several common  patterns for this.  The problem is only present if there is a need  to send messages asynchronously to the IoT device. A simple  thermostat for a home heating system only needs to send messages and  not to receive them. The receiver module connected directly to the  heating system could be mains powered, so that it just listens all  the time.

? Dave
