Owners can change the name of mashables, mashups and apps in Presto Hub that they registered or created. Presto administrators can change the name of any artifact. This does not change the ID that Presto assigns when you first add or create an artifact.
To change a name, open the artifact's page in Presto Hub from search results, bookmarks, favorites or other links and select Show > Info
Click on the artifact name, change the value and click Save.
