# Semantic Conventions for CouchDB **Status**: [Experimental][DocumentStatus] The Semantic Conventions for [CouchDB](https://couchdb.apache.org/) extend and override the [Database Semantic Conventions](database-spans.md) that describe common database operations attributes in addition to the Semantic Conventions described on this page. `db.system` MUST be set to `"couchdb"`. ## Attributes | Attribute | Type | Description | Examples | [Requirement Level](https://opentelemetry.io/docs/specs/semconv/general/attribute-requirement-level/) | Stability | |---|---|---|---|---|---| | [`db.operation.name`](../attributes-registry/db.md) | string | The HTTP method + the target REST route. [1] | `GET /{db}/{docid}` | `Conditionally Required` [2] | ![Experimental](https://img.shields.io/badge/-experimental-blue) | **[1]:** In **CouchDB**, `db.operation.name` should be set to the HTTP method + the target REST route according to the API reference documentation. For example, when retrieving a document, `db.operation.name` would be set to (literally, i.e., without replacing the placeholders with concrete values): [`GET /{db}/{docid}`](https://docs.couchdb.org/en/stable/api/document/common.html#get--db-docid). **[2]:** If readily available. Otherwise, if the instrumentation library parses `db.query.text` to capture `db.operation.name`, then it SHOULD be the first operation name found in the query.
