# Custom Metadata for Enhanced Asset & Monitor Context

We're excited to announce the release of **Custom Metadata**, a powerful new way to add rich, contextual information to your assets, monitors, and other entities within Sifflet! This feature allows you to define and apply your own key-value pairs, tailoring Sifflet to your specific organizational needs and workflows.

**Key New Functionalities:**

* **Define Custom Metadata Attributes:**
  * Create custom metadata fields with a specific **Key** (e.g., "Data Owner," "Project ID," "Sensitivity Level").
  * Choose from new **Value Types** for your metadata:
    * **User:** Assign Sifflet users.
    * **String:** Add free-text values.
    * **Label:** Select from a predefined list of options.
  * Specify which **Asset Types** (Datasets, BI Assets, Pipelines, Declarative Assets, Monitors) each custom metadata attribute can apply to.
  * Configure if an attribute can be used for **filtering** and if it supports **multiple values**.
* **Apply Metadata to Assets (individually or at scale):** Add or update custom metadata values directly in the "Details" section of an asset's "Overview" tab, or at scale by leveraging the [Bulk Actions](https://docs.siffletdata.com/docs/data-catalog#bulk-actions) in the Catalog or Monitors page.
* **Filter by Custom Metadata:** If configured, use your custom metadata attributes to filter assets in the Catalog and Monitors pages for improved discoverability.

**Why it Matters:**

* **Deeper Context:** Go beyond simple tags to add specific, meaningful information to your Sifflet entities.
* **Improved Organization & Discoverability:** Structure and find your assets more effectively using your own defined criteria.
* **Enhanced Governance:** Track ownership, sensitivity, compliance status, and other critical governance information directly on assets.
* **Streamlined Workflows:** Easily identify and manage assets related to specific projects, teams, or business units.
* **Customized Monitoring at Scale (Coming Soon)**: Leverage custom metadata to define monitoring strategies at scale based on your own criteria. (e.g., automatically creating Freshness Monitors for all tables that are part of a given project.)
