'' GNU libextractor is a library used to extract meta-data from files
|
|
of arbitrary type. It is designed to use helper-libraries to perform
|
|
the actual extraction, and to be trivially extendable by linking
|
|
against external extractors for additional file types.
|
|
|
|
The goal is to provide developers of file-sharing networks or
|
|
WWW-indexing bots with a universal library to obtain simple keywords
|
|
to match against queries. libextractor contains a shell-command
|
|
extract that, similar to the well-known file command, can extract
|
|
meta-data from a file an print the results to stdout.
|
|
|
|
Currently, libextractor supports the following formats: HTML, PDF,
|
|
PS, OLE2 (DOC, XLS, PPT), OpenOffice (sxw), StarOffice (sdw), DVI,
|
|
MAN, FLAC, MP3 (ID3v1 and ID3v2), NSF(E) (NES music), SID (C64
|
|
music), OGG, WAV, EXIV2, JPEG, GIF, PNG, TIFF, DEB, RPM, TAR(.GZ),
|
|
ZIP, ELF, S3M (Scream Tracker 3), XM (eXtended Module), IT (Impulse
|
|
Tracker), FLV, REAL, RIFF (AVI), MPEG, QT and ASF. Also, various
|
|
additional MIME types are detected.
