**Author:** `reflection` **Description:** I brought this up at Brion's "Extending MediaWiki" chat and was encouraged to file a bug report for it here. The stated problem is that an image dump contains no metadata concerning any of the images. Now that we have some level of EXIF integration, it seems logical to put image author, copyright, and description information into the appropriate EXIF fields. E.g., editing an image page makes an actual edit to the image itself. This no doube raises many issues, such as having wikitext inside an exif field, the md5 sums of the image (which I believe is how they are roughly stored in their directories), but it also solves a very large problem. Principally that our image dumps are distributed with absolutely no meta-data, which encourages irresponsibility in their use and could be illegal, as many of them are used by us as fair use. -------------------------- **Version**: unspecified **Severity**: enhancement

Image files downloaded from Wikimedia sites do not contain any information about the images (author, license, description page URL etc). This makes it hard to identify the source or the author in certain context (e.g. image reused on the web without proper attribution); arguably it causes certain ways in which Wikimedia publishes these files (such image tarballs) to be license violations. The situation could be improved by embedding this information into the file as metadata (e.g. EXIF fields). This is tricky as it would mean that the image needs to change on upload and potentially every time someone makes an edit to the file page; or we would have to make the original image hard to access and instead offer a modified version (a kind of full-size thumbnail) for download/view/export. --- **See also:** * T2657 - using metadat in the opposite direction * T20871 - the same issue for thumbnails * T95217 - same issue for audio files (Original reporter: `reflection`)
