In the Data Catalog user interface, you can create new metadata by adding business terms, term hierarchies, synonyms, and custom properties. Most user roles are permitted to add new terms as the users are browsing content. Only administrators can define new custom properties. Properties can be read or set by users who have the permissions to read and set.
You can change glossary items like domains, category, and terms using the Data Catalog user interface or undo the changes if necessary. You can also push the changes back to the tools from which they were imported into Data Catalog.
