The **top panel** shows key metadata at a glance: * **Source** — the connected data service * **Owner** — team or user responsible for the asset * **Tier** — data criticality level * **Type** — asset type (Table, Topic, Dashboard, etc.) * **Usage** — query and access frequency * **Description** — what the asset contains and how it's used Overview of Data Assets ## Data Asset Tabs Tabs vary depending on the type of data asset. The table below shows which tabs are available for each asset type. Data Assets Tab | **Tab** | **Table** | **Topic** | **Dashboard** | **Pipeline** | **ML Model** | **Container** | | :------------------------- | :-------: | :-------: | :-----------: | :----------: | :----------: | :-----------: | | **Columns** | ✔ | ✔ | ✘ | ✘ | ✘ | ✔ | | **Activity Feeds & Tasks** | ✔ | ✔ | ✔ | ✔ | ✔ | ✔ | | **Sample Data** | ✔ | ✔ | ✘ | ✘ | ✘ | ✘ | | **Queries** | ✔ | ✘ | ✘ | ✘ | ✘ | ✘ | | **Data Observability** | ✔ | ✘ | ✘ | ✘ | ✘ | ✘ | | **Lineage** | ✔ | ✔ | ✔ | ✔ | ✔ | ✔ | | **ER Diagram** | ✔ | ✘ | ✘ | ✘ | ✘ | ✘ | | **Knowledge Graph** | ✔ | ✘ | ✘ | ✘ | ✘ | ✘ | | **Contract** | ✔ | ✔ | ✔ | ✔ | ✔ | ✔ | | **Custom Properties** | ✔ | ✔ | ✔ | ✔ | ✔ | ✔ | | **Config** | ✘ | ✔ | ✘ | ✘ | ✘ | ✘ | | **Details** | ✘ | ✘ | ✔ | ✘ | ✔ | ✘ | | **Executions** | ✘ | ✘ | ✘ | ✔ | ✘ | ✘ | | **Features** | ✘ | ✘ | ✘ | ✘ | ✔ | ✘ | | **Children** | ✘ | ✘ | ✘ | ✘ | ✘ | ✔ | ## Columns Tab Available for **Tables, Topics, and Containers**. The Columns tab displays the full schema of the asset: * Column names, data types, and descriptions * Tags and glossary terms associated with each column * Frequently joined tables and their relationship context Columns Tab ## Activity Feeds & Tasks Tab Available for **all asset types**. This tab centralizes all collaboration and workflow activity for a data asset: * **All** — every activity on assets you own, follow, or are mentioned in * **@Mentions** — feeds where you're directly mentioned * **Tasks** — open tasks created by you or assigned to you, including approval requests and update requests Activity Feeds & Tasks Tab ## Sample Data Tab Available for **Tables and Topics**. If sample data ingestion is enabled for the connector, this tab displays a preview of actual data rows — making it easy to understand what the asset contains without writing a query. Sample Data Tab ## Queries Tab Available for **Tables only**. This tab shows all SQL queries run against the table: * Query text with syntax highlighting * When the query was run and how long it took * Whether the query is used by other tables * Ability to add new queries manually Queries Tab ## Data Observability Tab Available for **Tables only**. This tab consolidates profiling, data quality, and observability into a single view with the following sub-tabs: * **Overview** — test run summary (failed, success, open incidents, upstream failures) and test coverage by dimension * **Table Profile** — row count, volume trends, and table update frequency * **Column Profile** — value count, null %, distinct %, and unique % per column * **Data Quality** — test results at table and column level * **Incidents** — active anomalies and data quality alerts Data Observability Tab For more detail, see the [Data Observability Tab guide](/ai-2-0/how-to-guides/data-quality-observability/quality/tab). ## Lineage Tab Available for **all asset types**. The Lineage tab shows the full data journey for an asset: * End-to-end lineage at both table and column level * Upstream and downstream dependencies for each node * Clickable nodes that show asset previews with tags, schema, and quality metrics Lineage Tab Use the **Settings** icon to configure how many upstream/downstream nodes and layers to display. Use the **Edit** icon to manually add or adjust lineage connections using the no-code editor. ## ER Diagram Tab Available for **Tables only**. The ER Diagram tab shows the entity-relationship view of the table — how it connects to other tables through foreign keys and join patterns. This is useful for quickly understanding data model structure and table relationships. ER Diagram Tab ## Knowledge Graph Tab Available for **Tables** (Beta). The Knowledge Graph tab visualizes semantic relationships between the selected asset and other assets, glossary terms, and business concepts — surfacing hidden connections across your data platform. Knowledge Graph Tab ## Contract Tab Available for **all asset types**. Data Contracts define the expected quality, schema, and ownership agreement for a data asset. From this tab you can: * View any active contract and its compliance status * Create a new contract if none exists * Track who owns the contract and when it was last updated Contract Tab ## Custom Properties Tab Available for **all asset types**. Organizations can define custom attributes to extend standard metadata. This tab lets users view and edit those values directly — for example, business owner name, data classification, compliance tier, or SLA requirements. Custom Properties Tab Learn [How to Create a Custom Property for a Data Asset](/ai-2-0/how-to-guides/guide-for-data-users/custom). ## Config Tab Available for **Topics only**. The Config tab shows the technical configuration of a messaging topic, such as partition count, replication factor, cleanup policy, and retention settings. Config Tab ## Details Tab Available for **Dashboards and ML Models**. **For Dashboards** — displays the list of charts with: * Chart name and type * Description and associated tags **For ML Models** — displays Hyper Parameters and Model Store details. Details Tab ## Executions Tab Available for **Pipelines only**. The Executions tab shows a history of all pipeline runs: * Date, time, and duration of each run * Status: **Success**, **Failure**, **Pending**, or **Aborted** * View runs as a chronological list or as a tree * Filter by status and date range Executions Tab ## Features Tab Available for **ML Models only**. This tab describes the inputs used to train the model: * Model description * Each feature with its type, algorithm, and description * Data sources for each feature * Associated glossary terms and tags Features Tab ## Children Tab Available for **Containers only**. Lists all nested assets within the container — for example, files or sub-folders inside a storage bucket. ## Version History and Other Details The toolbar in the top-right of any data asset page provides quick access to: * **Tasks** — circular icon showing the count of open tasks * **Version History** — clock icon showing a log of major and minor metadata changes * **Follow** — star icon showing follower count; click to follow the asset and receive updates * **Share** — copy and share a direct link to this asset * **Announcements** — via the **⋮** menu; create or view time-bound announcements for the asset * **Rename** — via the **⋮** menu; rename the asset * **Delete** — via the **⋮** menu; permanently remove the asset Version History and Other Details Describe your data assets using Markdown
