Writing code is only half the battle in observability; the real challenge is ensuring that code speaks a universal language. As we move into 2026, the OpenTelemetry Semantic Conventions have expanded far beyond simple HTTP metrics into complex domains like GenAI, CI/CD pipelines, and Security. But how do these "standard names" actually get decided, and how can you influence them?

This session pulls back the curtain on the Semantic Conventions Special Interest Group (SIG). We will walk through the lifecycle of a convention: from identifying a gap in the OTel Registry to drafting a YAML-based proposal and navigating the stabilization process. We will also introduce OTel Weaver, the new CLI engine designed to automate the validation and generation of these conventions. Whether you are an end-user needing a custom domain registry or a developer wanting to contribute to the global standard, this talk provides a clear roadmap for moving "Beyond the SDK" and helping define the future grammar of observability.
