# Semantic Conventions for MongoDB
**Status**: [Experimental][DocumentStatus]
The Semantic Conventions for [MongoDB](https://www.mongodb.com/) 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 `"mongodb"`.
## Attributes
<!-- semconv db.mongodb(full,tag=tech-specific) -->
| Attribute | Type | Description | Examples | [Requirement Level](https://opentelemetry.io/docs/specs/semconv/general/attribute-requirement-level/) | Stability |
|---|---|---|---|---|---|
| [`db.collection.name`](/docs/attributes-registry/db.md) | string | The MongoDB collection being accessed within the database stated in `db.namespace`. [1] | `public.users`; `customers` | `Required` | ![Experimental](https://img.shields.io/badge/-experimental-blue) |
| [`db.namespace`](/docs/attributes-registry/db.md) | string | The MongoDB database name. [2] | `customers`; `test.users` | `Conditionally Required` If available. | ![Experimental](https://img.shields.io/badge/-experimental-blue) |
| [`db.operation.name`](/docs/attributes-registry/db.md) | string | The name of the command being executed. [3] | `findAndModify`; `getMore`; `update` | `Conditionally Required` [4] | ![Experimental](https://img.shields.io/badge/-experimental-blue) |
**[1]:** If the collection name is parsed from the query, it SHOULD match the value provided in the query and may be qualified with the schema and database name.
It is RECOMMENDED to capture the value as provided by the application without attempting to do any case normalization.
**[2]:** <!-- TODO: overriding the base note, workaround for https://github.com/open-telemetry/build-tools/issues/299 -->
**[3]:** See [MongoDB database commands](https://www.mongodb.com/docs/manual/reference/command/).
**[4]:** 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.

## Example
| Key | Value |
|:------------------------| :----------------------------------------------------------- |
| Span name | `"findAndModify products"` |

| `network.peer.address` | `"192.0.2.14"` |
| `network.peer.port` | `27017` |
| `network.transport` | `"tcp"` |
| `db.collection.name` | `"products"` |
