Buckets classify and store data snippets extracted from target pages. For example, on a blog page two buckets are defined. One is used to extract and store blogger's information. The other is used to extract and store the blog list. In order to extract a list two replicas must be mapped as stated in Manage replicas.
On the Extraction Editor work board, there are two buttons to manage buckets:
- newBckt: When the button is pushed, a new bucket is created. As a result, the work board is initialized so that the operations in Common Operations and Replica Management groupboxes are enabled and a property mapping table is initialized.
- Renew: When the button is pushed, the existing bucket is cleaned so that all properties are deleted. The operator should rename the bucket and recreate required properties.
