Similarly, a tool is known as extractor within Clowder framework to emphasize on the extraction of metadata from data content. An extractor is a program that extracts metadata within the file content, analyzes the file’s contents and tags it according to some specific classification or criteria, etc. It resides in distributed environment such as cloud, as extraction service and listens to a message queue for extraction requests from DTS API. The extraction process is triggered based on specific file types and the metadata extracted are made available through the DTS API.
In the BD framework, extractor and converter are the extensible units, and can be contributed by researchers across different research domains.
