UI Customization
Located in the $MM_HOME/conf/template/resources folder within the installation on the application server machine, the MetadataExplorer.xml file contains complete XML providing definition of the behavior of the Metadata Explorer UI. This is where we will include the new Environment for calls via URL.
To cause Talend Data Catalog to leverage any changes to this file (so that the UI is controlled by your updates) you must copy the file from $MM_HOME/conf/template/resources to $MM_HOME/conf/resources. Only when the file is in this new location will it be picked up and parsed on startup of the Talend Data Catalog application server.
The customization of this file is covered in detail in the Metadata Management Tutorial - User Interface Customization Using Talend Data Catalog
