Data Extraction: A transformation that creates new data from the given data. An example in the case of Brown Dog would be the execution of analysis code on an image file's contents to determine if a particular species of plant is present. We utilize extraction to automatically generate metadata and/or signatures from a file's contents and provide users with means of finding, relating, and utilizing data that may be difficult otherwise.
Data Set: A group of files that through some defined relationship or corresponding metadata are strongly tied together and not representable otherwise by the individual files.
