Please note that Semantic Conventions are tagged with the version of the [Semantic Conventions](https://github.com/open-telemetry/semantic-conventions/tags) that they were generated from. See . Stability ========= [](#stability) Semantic conventions are separated into `stable` and `incubating`. Both are generated from the [Semantic Conventions](https://github.com/open-telemetry/semantic-conventions) release with the same version as this package. Instrumentation authors should use stable conventions where possible, but may use incubating conventions. Deprecated conventions will be removed immediately from the next release after their deprecation, and there is no backwards compatibility guarantee for deprecated conventions. Stable ------ [](#stable) Stable semantic conventions (`OpenTelemetry\SemConv\Attributes\*` and `OpenTelemetry\SemConv\Metrics\*`) are based on all elements marked as `stable` and are considered safe for use in production. Incubating ---------- [](#incubating) Incubating semantic conventions (`OpenTelemetry\SemConv\Incubating\*`) contain both `stable` and `experimental` (in-development) elements. Experimental elements should be used with caution. Installation ------------ [](#installation) ``` composer require open-telemetry/sem-conv ``` Contributing ------------ [](#contributing) This repository is a read-only git subtree split. To contribute, please see the main [OpenTelemetry PHP monorepo](https://github.com/open-telemetry/opentelemetry-php). ### Health Score 61 — FairBetter than 99% of packages Maintenance78 Regular maintenance activity Popularity54 Moderate usage in the ecosystem Community37 Small or concentrated contributor base Maturity66 Established project with proven stability Bus Factor1 Top contributor holds 73% of commits — single point of failure How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
