Manage Presto Global Attributes
Presto global attributes define:
Default or common values that should be used for input parameters to mashables, mashups or apps.
Default or shared values for
Presto user attributes. For example, global attributes can define a credential that many users can share to invoke a mashable. Some users may have their own credentials which are defined as a
Presto user attribute of the same name.
To manage Presto global attributes
1. Click 
Admin Console in the Presto Hub main menu. 2. Open the Attributes section and click Global Attributes.
3. To add a global attribute:
a. Click Add new global attribute.
b. Enter a Name for the attribute.
Presto attributes can have any name, but they must be unique within a given Presto Repository. If a global attribute is to be used as a default for a Presto user attribute, then the attribute names must match.

The value of the attribute is encrypted in the Presto Repository and will automatically be decrypted when it is used.

4. To update a global attribute, click 
Edit for that attribute in the list and update the name or value. 5. To delete a global parameter, click 
Delete for that attribute in the list.
