Oracle WebCenter Content Server stores metadata under a document profile. A document profile is further nested into rules. To retrieve the metadata fields for mapping, you first select the WebCenter server, then the Content Profile, then the Rules set.
On the Custom Metadata header region, select the Rules as follows:
Server — Select the Web content server where the content profile is defined.
Content Profile — Select the content profile that includes the rules that define custom metadata fields.
Rules — Select the Rules set that specifies the metadata fields.
If you do not select a Rules set, then BI Publisher loads the metadata for all Rules under the Content Profile.
Click Load Metadata. The lower pane displays the metadata fields defined in the Rules you selected.
