= 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.
