= Description = The [http://natlib.govt.nz/librarians/digital-library-tools Metadata Extraction Tool] automatically extracts a limited set of metadata from the headers of digital files; it has the capability to process both individual files and larger batches. The Tool outputs this information as XML, with the goal of facilitating transfer into a preservation metadata repository. ====Provider==== The National Library of New Zealand (NLNZ) ====Platform and interoperability==== The software uses Java and XML, and has been tested in Windows and Linux/Unix environments. ====Functional notes==== The Metadata Extraction Tool uses a library of ‘adapters’ to extract metadata for specific file types. Adapters have been created for the following formats: BMP, GIF, JPEG and TIFF; MS Word, Word Perfect, Open Office, MS Works, MS Excel, MS PowerPoint, and PDF; WAV, MP3, BFW, and FLAC; HTML and XML; and ARC. If the file type is unknown the Tool applies a generic adapter, which extracts a limited amount baseline metadata. The application opens all files as read-only, ensuring the integrity of original files. ====Documentation and user support==== The Tool’s [http://meta-extractor.sourceforge.net/ Sourceforge page] includes user and installation guides, as well as a developer guide. Users can report bugs through the Sourceforge site, which also lists a contact email. ====Usability==== The tool has both a GUI and command line interface. ====Expertise required==== Installation and configuration require solid knowledge of application design and technologies. Users should have comprehensive knowledge of metadata standards and formats, particularly regarding preservation metadata. ====Standards compliance==== The Metadata Extraction Tool currently outputs its XML files using the NLNZ preservation metadata schema; however, the software can be configured to support other schemas. ====Influence and take-up==== Sourceforge statistics show approximately 38,000 downloads since 2007. = User Experiences = <!-- Add hotlinks to user experiences with the tool (eg. blog posts). These should illustrate the effectiveness (or otherwise) of the tool. Use a bullet list. --> * '''FITS (File Information Tool Set):''' Used in [[FITS (File Information Tool Set)|FITS]] = Development Activity = Version 3.5GA was released in June 2010. Latest release 3.6GA is from 2014. The initial version of the tool was released in 2003; redevelopment for version 3 began in 2007.
