Thank you all for your input. Some of the resources had been new to me, but still only the Tutorial suggested by @JustinG contains some sparse information. Some questions are still open:
- is the publication of an BlockLibrary some automated process or is the forum entry checked manually by some Admin and copied somewhere else?
- maybe related: how are code updates handled? If I provide the code via a " direct link to a *.yaml file hosted by [my] preferred service", will the (openhab marketplace) accessible version of the published file immediately change when I change the hosted file?
- How to release a bundle of multiple BlockLibrary files, which are required to be used together?
Thanks for your help, best regards, Rene
