1. Select the **Source Data Space** that contains the semantic model you want to extend.
    
    The bridge lists the semantic models available in the selected data space.

    Only C360 semantic models are supported for extension.

The bridge shows the base semantic model and source data space at the top of each subsequent step.

## Review and Select Source Reports

After selecting a semantic model, choose the report types whose data you want to include in your semantic model.

![Select the source reports to use in your semantic model](https://sf-zdocs-cdn-prod.zoominsoftware.com/tdta-analytics-analytics-264-0-0-production-enus/295fead5-b71d-4e1c-9886-4af4d53400b6/analytics/images/rd_analytics_metadata_bridge_review_and_select_source_reports.png)
