FS#474 Metadata for media files

  In a document management scenario for Dokuwiki it becomes necessary to use a lot of attached files (images, documents, etc.) when a complex layout is required (flowcharts, forms, brochures). It would be very useful to add  some sort of metadata functionnality where keywords or an abstract could be linked to attachments, which then could be searched along with everything else.
  
  An additional field in the file attachment dialog ("Comments") would do the trick. Additional fields ("Title", "Author", etc.) could be added later or left as an option. This could create a, say, myimage.txt in the media directory which would contain the metadata. This is discussed here: http://wiki.splitbrain.org/wiki:discussion:filemanagement?s=metadata

  I would like to see this improvement for dokuwiki too. It would be very helpful for me, if metadata could be added to mediafiles and found during search.
  
  Examlpe: at the momenent, I use dokuwiki for bugreporting and discussion on software developing. If attached images are tagged with the metadata "version", it would be possible to find all depricated files after a new version comes out.
  
  Note: Although I would prefer to use *.png, I could live with *.jpg, if their IPTC-comments are made searchable. But I think a "On the Fly Query" looking into jpg-files would be not a preferable solution (performance reasons).

  There is today [wikiroot]/data/media_meta/
  I guess (almost) the only metadata of media that is stored, that are the changelogs
