# 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 |
|---|---|---|---|---|
| [`db.mongodb.collection`](../attributes-registry/db.md) | string | The MongoDB collection being accessed within the database stated in `db.name`. | `customers`; `products` | Required |
<!-- endsemconv -->
