Xtract is an extendable, scriptable data extraction framework. It is meant to be a unified framework to perform data extraction tasks. It includes a sample module to identify JPEG files. A common, shared framework similar to this makes it possible to develop an easily deployable and commonly held set of data extraction tools that exceed the capability of any closed-source alternative. The script-based nature of Xtract makes it portable across architectures, and its modular design allows the easy addition of capabilities to identify new types of files or other data.
