Here is the draft plan for logs: https://github.com/open-telemetry/opentelemetry-specificatio...

Logs are not going to be part of OpenTelemetry 1.0 release (only traces and metrics will). Logs are coming later (no specific timeline yet).

Disclaimer: I work on OpenTelemetry spec and wrote most of the linked doc. Comments/issues/PRs welcome in the repo.
