A Bean is casted from a Bucket and its Properties. This bean is just like that bean in Java, which has many properties too.

In fact, Buckets and Beans are both containers with an one-to-one relation between each other, which are used in different phrases of data extraction via MetaSeeker toolkit. In phases of defining data schema and extracting data, Bucket is used as a container to classify and structure data snippets on a Web page semantically. In phase of outputting extracted results, Bean is used as a container to store the results. As a result, in Data Extraction Result Files, instead of a XML tag named as bucket there are XML tags named as bean which embrace their properties into a semantical entity.
