GNU libextractor
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, file managers, and WWW-indexing bots with a universal library to obtain meta-data about files. It includes a shell-command and bindings for Java (JNI) and Python.

Release Notes: This release fixes plugin discovery on OS X. Nothing has changed on other systems, so there is no need to update from 1.0.0 on non-OS X systems.
- 25 Sep 2012 21:43
Release Notes: Major changes to the plugin mechanism now allow out-of-process plugins full random access to the entire file. Most plugins have been rewritten to the new plugin API. The external (libextractor) API remains unchanged and compatible with 0.6. As part of the rewrite, many plugins were changed to use standard 3rd party libraries (libjpeg, libtiff, libgif, libtidy, and libmagic) for parsing. A new plugin based on gstreamer replaces many existing multimedia plugins. Automated test cases for (almost all) of the plugins were also written, and the documentation was updated.

Release Notes: This release adds support for Matroska, fixes some minor bugs (leaks on error-handling paths), and does some minor code clean up (fixing compiler warnings about dead code).
- 14 Jun 2010 11:23
Release Notes: This release fixes various minor bugs, in particular better handling of malloc failures and more robust handling of malformed inputs in various plugins.

Re: online demo not working
There are two PDF plugins, one that is quite
simplistic and another one based on code from
xpdf (which has a bad security track record).
Depending on which one I happen to enable on the
website (options to configure), you get more or
less information for PDF files.

Re: Also Requires gobject-2.0
Note that as of 0.5.3 LE still needs gobject-2.0 but the
ordinary shared version will do fine now.
Re: Also Requires gobject-2.0
Well, gobject-2.0 is part of glib, so it is listed as a
dependency. What is more tricky is that we need the
static, relocatable version of the library -- but try to specify
that on freshmeat :-).
Also Requires gobject-2.0
Can't seem to get the OLE2 libraries to compile, make complains:
/usr/lib/gcc-lib/i686-pc-linux-gnu/3.3.3/../../../../i686-pc-linux-gnu/bin/ld: cannot find -lgobject-2.0
Oh, and you may want to include these dependencies within either the README or INSTALL files.
