# General Semantic Conventions This document defines general Semantic Conventions for spans, metrics, logs and events. The following general Semantic Conventions are defined: * **[General attributes](attributes.md): General semantic attributes**. * [Events](events.md): General Semantic Conventions for events. * [Logs](logs.md): General Semantic Conventions for logs. * [Metrics](metrics.md): General Semantic Conventions for metrics. * [Spans](trace.md): General Semantic Conventions for traces / spans. ## Event Name Reuse Prohibition A new event MUST NOT be added with the same name as an event that existed in the past but was renamed (with a corresponding schema file). When introducing a new event name check all existing schema files to make sure the name does not appear as a key of any "rename_events" section (keys denote old event names in rename operations).
