-# OPENTELEMETRY COMPONENTS
-#
-# Some OpenTelemetry components run within end-user applications and thus have
-# a footprint across many languages. Naturally, the production and API maturity
-# of these components varies from language to language. Other components run as
-# infrastructure in their own containers or VMs and thus have a single maturity
-# level regardless of the end-user's programming language.
-#
-# The maturity – or even the existence – of the "perLanguageComponents" varies
-# from language to language. These are components that integrate into the
-# actual end-user application runtime in production. See "languages" for the
-# actual maturity levels.
-perLanguageComponents:
-  - traceAPI
-  - metricsAPI
-  - contextAPI
-  - traceSDK
-  - metricsSDK
-  - contextSDK
-
-# The maturity of the "standaloneComponents" is independent of any particular
-# end-user programming language.
-standaloneComponents:
-  collector:
-    api: alpha
-    production: beta
-  operator:
-    api: alpha
-    production: beta
-
-# For each language, we either specify the perLanguageComponents maturity
-# inline, or we specify a single "url" that points to another YAML file with a
-# top-level perLanguageComponents key (presumably in the OpenTelemetry language
-# repository). E.g., something like this:
-#
-# languages:
-#   pascal:
-#     repoUrl: "https://github.com/open-telemetry/opentelemetry-pascal"
-#     maturityUrl: "https://raw.githubusercontent.com/open-telemetry/opentelemetry-pascal/master/maturity.yaml"
