There is already the discussion 17503 about generating metadata by checking
licensing/author info or information template from the media description page,
but the progress is disappointingly slow. Rubbish or not, it's still better
than containing no metadata at all in the resized file. Please prove that
metadata is ever the culprit of oversized media file.

I dont think thats the expected result. Lots of useless crap in the metadata.

However there are some fields which would be nice to copy over like artist

We also add a field to thumbnailed images to link to the source (but possibly
not with vips, so not for really big pngs. Probably also not for svgs).

Im confused about if you are complaining about svgs (vector) images specificly
or all files. You talk about vector formats in comment 0 but pngs (raster) in
comment 2.

 After the change of Wikimedia that the file description page no longer
 provides original size preview if the width of the original raster image is
 too long, the down-scaled version is always the one being shown.

That's incorrect, the situation is not new. This is the way its always been. We
show the original image asset where possible, but we're not display huge files
inline on the image description page. Some of those original image files are
hundreds of megabytes big. There's even a tiff file which is 1 GB big.

Thanks for taking the time to report this!

What would be steps to follow if I wanted to reproduce? Any testcase?

(In reply to Andre Klapper from comment #1)
 Thanks for taking the time to report this!
 
 What would be steps to follow if I wanted to reproduce? Any testcase?

Steps to reproduce:
1) Access the description page of any oversized PNG file with metadata at
Commons like File:FutureMTRNetworkAfterMerger.png
2) Download both the original file and the resized preview.
3) Use any application capable of reading Exif/XMP like ExifTool to read both
version of the image.
4) Compare the metadata between the 2 files
5) The resized file contains fewer metadata than the original file.

Expected: resized image should contain all metadata from the original file.
