FlickreviewR searching for license changes

[edit] FlickreviewR

Currently a lot of Flickr images are uploaded to the Commons. As Flickr allows the uploaders to change their licensing at any time, images must be confirmed to have a copyright status acceptable on Commons. Up until November 2006, this was solely the task of administrators. This resulted in a huge backlog of unreviewed images. FlickreviewR is a bot that checks the image status at Flickr, and confirms whether the license on Flickr is one acceptable on the Commons.

[edit] Task description

FlickreviewR's primary task is to scan the images in Category:Flickr review needed. However, since there are a lot of images uploaded in lower quality, its second task is to replace those images with the original version.

[edit] Review

• FlickreviewR first retrieves a list of images from Category:Flickr review needed.
• It then tries to extract the link to the Flickr image from the description.
• Then the exif data is extracted from the database and compared with the exif data from Flickr.
  • If those do not match, or a higher resolution of the file on Commons is available from Flickr, the image of corresponding size is downloaded from Flickr and their MD5 sums are matched.
• If the images on Commons and Flickr match, the license status is reviewed and the result posted to Commons.
• If the images on Commons and Flickr match and the license is compatible with Commons and a higher resolution of the file on Commons is available from Flickr, the high resolution version is uploaded.
• Images that were unreviewable are categorized into Category:Flickr images needing human review.

[edit] Return values

The bot can return the following values and indicates them as such in the log:

• Passed: The image on Flickr and the Commons are the same, as well as the license.
• Failed: The image on Flickr and the Commons are the same, however the licenses are not, and the license on Flickr is not allowed on the Commons.
• Passed_Changed: The image on Flickr and the Commons are the same, however the licenses are not, but the license on Flickr is allowed on the Commons.
• Md5_Not_Matching: The MD5 comparison failed.
• Size_Not_Found: No exif comparison was possible or failed, and the image is not available in the same size on Flickr.
• No_Flickr_Link: A link to the correct Flickr page is absent on the image description page.
• Flickr_Not_Found: The image was no longer available or private.

[edit] Old return values

Older reviews may also return the following values. In the database they are converted to Exif_Error or Error.

• NOT_CC_TAGGED: No Creative Commons license could be found on the image description page
• UNKNOWN_LICENSE: The image on Flickr is tagged with an unrecognizable license
• NO_EXIF: The Commons does not have any EXIF information regarding the image
