The Elastic Common Schema (ECS) defines a common set of fields for ingesting data into Elasticsearch. A common schema helps you correlate data from sources like logs and metrics or IT operations analytics and security analytics.
In April 2023, OpenTelemetry and Elastic made an important joint announcement. In this announcement, we shared our intention to achieve convergence of ECS and OTel Semantic Conventions into a single standard maintained by OpenTelemetry.

Various kinds of files or programs can be generated based on ECS. You can learn more in generated/README.md
The main branch of this repository should never be considered an official release of ECS. You can browse official releases of ECS here.
The ECS team publishes improvements to the schema by following Semantic Versioning. Generally major ECS releases are planned to be aligned with major Elastic Stack releases.
