Metadata Extraction Tool
http://meta-extractor.sourceforge.net/

The Metadata Extraction Tool was developed by the National Library of New Zealand to programmatically extract preservation metadata from a range of file formats like PDF documents, image files, sound files Microsoft office documents, and many others. The tool was initially developed in 2003 and released as open source softtware in 2007. The current version can be downloaded from the SourceForge download page. The Tool builds on the Library’s work on digital preservation, and its logical preservation metadata schema. It is designed to: a) automatically extracts preservation-related metadata from digital files, and b) output that metadata in a standard format (XML) for use in preservation activities. The Tool was designed for preservation processes and activities, but can be used to for other tasks, such as the extraction of metadata for resource discovery. The Metadata Extract Tool includes a number of adapters that extract metadata from specific file types. Extractors are currently provided for: 1) Images: BMP, GIF, JPEG and TIFF, 2) Office documents: MS Word (version 2, 6), Word Perfect, Open Office (version 1), MS Works, MS Excel, MS PowerPoint, and PDF, 3) Audio and Video: WAV and MP3, and 4) Markup languages: HTML and XML. If a file type is unknown the tool applies a generic adapter, which extracts data that the host system ‘knows’ about any given file (such as size, filename, and date created). This has been added to the tools section of Research Resources Subject Tracer™ Information Blog. This will be added to Web Data Extractors white paper link compilation.
