Extend ArcGIS Pro with ArcGIS Pro Metadata Toolkit. The ArcGIS Pro Metadata Toolkit is based on the add-in and configurations extensibility pattern. This toolkit provides resources to support customizing the pages that appear in the ArcGIS Pro metadata editor to suit your organizational, community, or regional requirements. Customize the metadata display within ArcGIS Pro, and how metadata is imported to and exported from the ArcGIS Metadata XML format. Your modifications can be distributed as an ArcGIS Pro Metadata add-in.
