Work Package for Struct Proposal:
Details of the proposal in [PR 511](https://github.com/COVESA/vehicle_signal_specification/pull/511/)

A. Minor release with experimental struct support  
1. vss-tools can take in a types spec file and process sensor tree and the type tree together. struct/type support will be marked as an experimental feature.
    a. Syntactic check of struct definition
    b. Semantic check of type references in sensors
    c. Demonstrate working using the JSON exporter
2. Add disclaimer/warning when customer is using experimental feature 
3. Warning in exporters that structs are not yet supported
4. Warning in overlays that structs are not yet supported
5. Experimental feature documentation
Effort: 3 weeks

B. Exporters release  
1. Add support for struct types in other text-based available exporters in vss-tools - CSV, YAML
Effort: 1 week

C. Major release  
1. Overlay support
2. Documentation update
3. Add support for non-text exporters as needed - protobuf, DDSIDL, etc.
4. Add guidance around when and how to use struct types
Effort: 4 weeks

    • Reference: https://docs.google.com/document/d/1dHHMIlIZpsbnVsTiiza4Suua-vVbfR1xm11KNKdAm38/edit 
    • Grouping of signals - is there a mechanism to group signals.
    • Best way forward - create issues for most important areas to describe problem and wanted solution and continue discussion
  • Ford proposal - Fleet based range prediction
    
    • Christoph Schierjott presents EV Charging Event Data Aggregation Project
    • Data upload of various data to cloud
    • Cloud calculates correction factor individually and sends down to vehicle to correct fleet range prediction
  • Power Optimize
    • Mobis Architecture
      • Intention is to have a power manager that will select scheme, either based on user request or for example based on that remaining power drops below 20%
    • Pre-information Bosch proposal
      • Erik: Bosch has some ideas on representation that will be presented in the Power Optimize meeting this week

Meeting 2022-12-20

• Compliance statement - TBD
• Welcome and agenda discussion - anything that needs to be added?
• Prioritized topics
  • Aggregate vs. structs - when do we see it need to be kept
    • From last week - Ulf/Erik: In favor of deprecating/removing aggregate keyword
    • Since then: Ulf requested a credible example, Erik stated that if we are to keep it we should better propose/specify how tools shall handle it
    • Adnan: Allow aggregate on deployment level, can use it when needed. For now good to only have it as information.
    • Krishna: Thinks aggregate makes changes, struct does not affect it. If we want to depricate we can do it later
    • Ulf: Does not have a strong opinion
    • Adnan: Good to document when structs vs aggregate shall be used
    • Erik: Can update the PR
    • Erik: Do you Krishna have interest in doing actual work.
    • Krishna: In January will start working on it, can help Erik
    • Erik; Then we can discuss later when we think it will be ready for VSS 4.0 release
  • Information: Overlays after expansion
    • Internal Bosch discussion if it would be better to refactor tooling so that only one parameter needed and tool is "smart enough" to deduce if given path refers to extended entity or not.
  • Discussion: PowerOptimize PR
    • Chandra: Intention to have one branch in each area, for infotainment we see brightness and audio volume
    • Chandra: Does not intend to duplicate, only want one signal, need only one
    • Erik: Isn't PowerOptimize only one of many use-cases for e.g. brightness, why need a PowerOptimize branch
    • Chandra: If scattered more difficult to find
    • Sebastian: OEM needs to decide what is part of his power optimization, do not understand the value of having them in separate branch
    • Adnan: What is difference
    • Pradeep: Adding a feature set, complete algorithm,
    • Adnan: If you are only proposing values, then it makes sense
    • Sebastian: Alternative usages could be e.g. overlay
    • Chandra: When we explain we see some signals are duplicated
    • Adnan: Best solution would if you prepare and show architecture on how it is intended
    • Adnan: Have not seen scope. Like to learn how
    • Pradeep: Do you have any public link describing how it is supposed to work.
    • Adnan: if you create some simple document you can attach it, then we can try to find best way
  • UUID elements
    • Adnan: Is anyone using UUIDs at the moment
    • Sebastian: We have never used them
    • Adnan: We saw a potential of UUID, could help versioning. We could UUID hash to validate. Has anyone any ideas. Otherwise we might create improvement proposal.
    • Sebastian: UUID are as of today generated based on tree structure.
    • Adnan: We need more, e.g. history. How do we move leave but keep UUID.
    • Sebastian: Could be a hash of only name/description/....
    • Erik: Please Adnan create an issue and ask if someone use UUIDs - if not you are free to do anything.

• Welcome and agenda discussion - anything that needs to be added?
• Prioritized topics
  • Continued struct decision, focus on recommendations/limitations, why we need it, rationale (https://github.com/COVESA/vehicle_signal_specification/pull/511)
    • Meeting notes:
      • Krishna - for types - there could be subtrees working as namespace. Erik to improve description.
      • Adnan - we need to come up with how to use "Aggregate"
      • Krishna - could be useful for aggregating
      • Adnan - we need to explain advantage of aggregate vs struct
      • Erik to create proposal in document
      • If no further comments, next step is to identify work packages in detail and do estimation for roadmap
  • Ulf presented some roadmap ideas (15-20 minutes)
    • Proposals:
      • Reason - to get a domain agnostic taxanomy
      • Move "rule set" to new specification project, VSS keeps the catalog.
    • Sebastian: Could be an idea to scope it to "mobility only"
    • Erik: Could at least be idea to have a vision/mission for the "rule set" to primarily support mobility use cases
    • Daniel: Integrating/reference domains in Yaml does not make sense, Ontology is a better choice. This is the next step of VSSo.
    • How to proceed:
      • Document to be uploaded
      • Discussion to be continued at some later time (not urgent)
      • Interesting topic for next AMM, including VSS ↔ VSSo relationship
