my experience / practice was to upload all, and then manually add to other images field, then curate the metadata among images. you may have multiple versions from different sources, i.e. google art, museum flickr feed, some duplicates got deleted, but there is no process for image curation among duplicates. (yet) i found in general that there were no tiffs, only some high res jpgs around 20MB taken from tiffs. jim hayes On Fri, May 2, 2014 at 4:40 AM, Fæ <faewik(a)gmail.com> wrote:

Hi Dan, It probably should still output a warning and list all identical files, so they can be tackled manually after the upload. Giving preference to the media file from the GLAM probably makes sense, but you still want to substitute any other identical files, right? When manually tackling identical files, the following potential issues should be looked at: - Existing files may already be included into Wikipedia articles - it probably would make sense to replace them by the newly uploaded version - Metadata of existing files may be more complete or complementary to the metadata provided by the GLAM, especially if it has been enhanced by the community (translations, etc.) - it certainly would make sense not to throw away these additional metadata that have been contributed by the community. - There might be derivatives based on existing files - it certainly makes sense to ensure that they can be properly tracked to the original file This may not be complete; maybe someone actively involved in uploads that have encountered the problem of such duplicates wants to go through the list, complement it and add it to the help/documentation pages...

GWToolset ignores the SHA-1 duplication warning. as far as i remember, the intent is to make sure the source of the mediafile and metadata is from the GLAM. with kind regards, dan On May 3, 2014, at 09:36 , Fæ <faewik(a)gmail.com> wrote: _______________________________________________ Glamtools mailing list Glamtools(a)lists.wikimedia.org https://lists.wikimedia.org/mailman/listinfo/glamtools

Am I understand correctly, you suggest to remove volunteer uploaded files by GLAM uploaded files? charles

GWT should prevent the upload of duplicates. Not enough users are working on the backlog... https://bugzilla.wikimedia.org/show_bug.cgi?id=64831 Date: Sat, 3 May 2014 04:29:12 -0300 From: bawolff(a)gmail.com To: glamtools(a)lists.wikimedia.org Subject: Re: [Glamtools] Advice on uploading a batch from a GLAM when individuals have already uploaded some of that GLAMs images?

Anyways they can be dealt with after the fact too if they are exactly identical as its easy to detect later. > > > > > > > > > > > > > > > > > _______________________________________________ Glamtools mailing list Glamtools(a)lists.wikimedia.org https://lists.wikimedia.org/mailman/listinfo/glamtools
