Note: This release is in preview. Features described here don’t become generally available until the latest general availability date that Salesforce announces for this release. Before then, and where features are noted as beta, pilot, or developer preview, we can’t guarantee general availability within any particular time frame or at all. Make your purchase decisions only on the basis of generally available products and features.
Extended Metadata (XMD) Reference
Any fields in the XMD that aren’t described in this document aren’t supported and must not be customized. Configuring unsupported fields might cause unexpected behavior. You also can’t export XMD. When saving XMD files, use UTF-8 format to be sure that Analytics visualizations correctly display international characters.
Almost all of the XMD functionality is now supported in the UI for editing datasets and lenses. The Edit Dataset page allows you to customize actions for the dataset, and the Lenses Dataset Fields section allows you to customize other actions.
