Content Management System (CMS)
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
Extractor: A tool which takes a file, section of a file, data set, or collection as input and through some analysis of the contents produces some higher level information, e.g. metadata, or other derived product, e.g. preview, to aid users in searching/organizing data (both automatically and/or manually).
