| [unide-dev] Discussion today: Unide |
|
Hello, Today, we had a very fruitful discussion with Frank Patz-Brockmann. Your feedback would be appreciated! We concluded the following regarding PPMP/Unide: ·
PPMP (v3) shall
o
not include additional complexity but rather prepare the basis for extension mechanisms
o
remain a one-way communication stream
o
describe the process for requesting new features / collaborate [Frank]
o
include a set of documentation / recommendations:
§
include an architecture blueprint and describe the relation to io-link, OPC-UA, Cloud etc.
§
should describe the functional use of the PPMP properties or create a data dictionary, glossar, onthology
§
how to project machine hierarchy (see prev. bullet)
§
should propose ways for further specialiazation / context. e.g. describe measurement value unit, datatype, offset, multiplier, accuracy etc.. Nevertheless, this shall
not be included in every payload nor shall we reinvent io-link or other standards
·
make use of existing definitions, like UN/CEFACT [1]
·
review JSON schema extensions, Vorto, ditto to cover these extended information instead of including in PPMP payload itself [Axel]
§
how to send PPMP payload over REST / mqtt or other (deviceId in url/topic)
§
for converting to binary / protobuf [Axel]
§
how to convert / upgrade from previous PPMP version
o
shall define the length for all fields [Axel]
o
shall review the spelling of the fields (ID, Id, id, part.id, part.partId etc)
o
can split operationalState into operationalMode and deviceState
o
can include a state (active, info, inactive) for events to indicate if an issue has just started or is over now ·
Unide
o
Unide 0.3.0 shall include a C (Alois?, Contact) binding. C# (Microsoft) binding and go binding (influx)
o
Bindings shall also be able to convert / upgrade from previous PPMP versions
o
Follow up with Benjamin & Microsoft regarding ways of working together (same goes for testbed)
o
Reach out to further interested parties (Promess, Trumpf, itac) [Axel] Mit freundlichen Grüßen / Best regards
