I am writing a Python script to index a large set of Windows installers into a DB.
I would like top know how to read the metadata information (Company, Product Name, Version, etc) from EXE, MSI and ZIP files using Python running on Linux.
I am using Python 2.6.5 on Ubuntu 10.04 64-bit with Django 1.2.1.
Windows command line utilities that can extract EXE metadata (like filever from SysUtils), or other individual CL utils that only work in Windows. I've tried running these through Wine but they have problems and it hasn't been worth the work to go and find the libs and frameworks that those CL utils depend on and try installing them in Wine/Crossover.
Win32 modules for Python that can do some things but won't run in Linux (right?)
Obviously changing the file's metadata would change the MD5 hashsum of the file. Is there a general method of hashing a file independent of the metadata besides locating it and reading it in (ex: like skipping the first 1024 byes?)

Implementation: Importing modules. Load the image and extract the exif data. Convert the exif tag id(denoted by tagid in the code ) into human readable form denoted by tagname in the code and getting its respective value.
metadata, is a Python module for accessing and managing an item's metadata. You can explore information describing your maps and data and automate your workflows, particularly for managing standards-compliant geospatial metadata.
Create Metadata We can create the metadata for the particular data frame using dataframe. scale() and dataframe. offset() methods. They are used to represent the metadata.
Take a look at this library: http://bitbucket.org/haypo/hachoir/wiki/Home and this example program that uses the library: http://pypi.python.org/pypi/hachoir-metadata/1.3.3. The second link is an example program which uses the Hachoir binary file manipulation library (first link) to parse the metadata.
The library can handle these formats:
Additionally, Hachoir can do some file manipulation operations which I would assume includes some primitive metadata manipulation.

The hachoir-metadata get the "Product Version" but the compilers changes the "File Version". Then the version returned is not the we need.
I found a small a well working soluction:

I've tested with success. It's simple, fast and stable.
