Committers, please vote.
- Update on Sparkplug specification work.
- Majority of spec port completed.
- Lots of cleanup to be done.
- Missing:
- Normative statements linked to source code
- General cleanup, errata fixed,
- New build infrastructure is in place.
- Uses Maven
- Reviewed root POM file
- “mvn generate sources” will produce the final version of the spec (HTML, PDF)
- Sparkplug_spec.adoc defines which chapters are consumed as part of the build process.
- Allows for dynamic TOC building
- TOC max level configuration
- TOC linking still possible within the spec
- Goal mid-summer 2021 release of initial version of the spec.
- We are only getting half participation in our Sparkplug Specification Project meetings... hopefully as we bring more folks in we can accelerate work completed.
- Where do the Sparkplug A & B payload definitions belong?
- In the actual spec or as separate docs?
- There will likely be a Sparkplug C in the future. Do implementers need to implement all versions to be “compatible”?
- Will Sparkplug C (JSON) become the defacto standard payload format?
- Proposal: Move the payload definitions to the appendix? They will still include normative statements, links within the spec to payload specifics when necessary.
- Decision: Undecided. The group will continue to think on this.
- Proposal: Drop the Sparkplug A definition all up and do not include in the spec.
- Decision: Approved. We will include a footnote somewhere within the spec that acknowledges the Sparkplug A, but that will be it.
- Goals for the next 2 weeks
- Continue and hopefully finish the spec port.
- One E2E example with TCK annotations/normative statements.
- If Ian Craggs joins the team, what is the best way to leverage his skills and get him up to speed?
Thanks,
Nathan
