 Metafacture is a toolkit for processing semi-structured data with a focus on library metadata. It provides a versatile set of tools for reading, writing and transforming data. Metafacture can be used as a stand-alone application or as a Java library in other applications. The name Metafacture is a portmanteau of the words *meta* data and manu*facture*.
 
-Metafacture includes a large number of modules for operating on semi-structured data. These modules can be combined to build pipelines to perform complex metadata processing tasks. The pipelines can be constructed either in Java code or with the domain-specific language **Flux**. One of the core features of Metafacture is the **Metamorph** module. Metamorph is an xml-based language for specifying transformations of semi-structured data. It can be seamlessly integrated into Java code.

 At its heart Metafacture is a framework for implementing modules for metadata processing. This makes Metafacture easily extendable with additional modules. The [plugins and tools page](https://github.com/metafacture/metafacture-core/wiki/Plugins-and-Tools) on the wiki shows supplementary packages and projects which extend Metafacture.
