 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*.
