Metadata in Talend Studio is definitional data that provides information about or documentation of other data managed within Talend Studio.
In the Integration perspective of the studio, the Metadata folder stores reusable information on files, databases, and/or systems that you need to create your Jobs.
Various corresponding wizards help you store these pieces of information and use them later to set the connection parameters of the relevant input or output components, but you can also store the data description called "schemas" in your studio.
Wizards' procedures slightly differ depending on the type of connection chosen.
This chapter provides procedures to create and manage various metadata items in the Repository that can be used in all your Job designs. For how to use a Repository metadata item, see How to use centralized metadata in a Job and How to set a repository schema.
Before starting any metadata management processes, you need to be familiar with the Graphical User Interface (GUI) of your studio. For more information, see the appendix describing GUI elements.
