Write metatags to EPS and JPG files out of Inkscape SVG images

[peterburger]

Hi all,
I've just finished a solution to entering metadata from an Inkscape SVG file to generated EPS and JPG files. This is a problem for stock image artists.
The EPS file is made with Save As EPS. The JPG file is generated via convert (from ImageMagick), due to Inkscape exports PNG files only with Bitmap Export.
Inkscape handles metadata within its own SVG format only, thats why the EPS, PNG and JPG files don't have any practicable metadata.
ExifTool was the only program I've found, which was able to read this SVG tags. Thank You very much Phil!
With a "stack" file in XML and three .args files the relevant metadata can now be written to the generated EPS and JPG files.
As I'm not familiar with Perl I've done the job with a Python script.
Maybe there are other / better solutions, but they should kept as simple as possible.
The complete stuff is in the attached ZIP file for a further discussion.
Greetings
Peter.
