What's Micrometer story for library owners

• Which one to use Otel or Micrometer. Why?
• Semantic conventions - how users can pick which ones they want? will libs need to provide all possible options?
• What's the story in other languages/ecosystems? I need my python messaging consumer to be consistent with my java messaging producer.
• Which libraries beyond Spring are all-in on Micrometer?
• How do you prioritize features? What if something is missing? (E.g. structured events on spans, adding link after span creation, etc)
  • is Micrometer targeting feature-parity with OTel specification? Will micrometer introduce profling API?
• How big is the community? Are there community calls? Who makes decisions?

Schema transformation tooling

1. Schemaprocessor in collector-contrib. It's a stub and does not do anything. It's not included into collector-contib image.

2. Search for https://opentelemetry.io/schemas/ does not show if anyone uses transformation logic.

3. There is no schema transformation logic in exporters in opentelemetry-collector-contrib repo.

4. There is a schema parser https://pkg.go.dev/go.opentelemetry.io/otel/schema/v1.1
