Dear Jean-Fred, Laura, Gergo, Brian and Nemo,

Thanks so much for your helpful answers to this question!

Nemo, your wikistats link is particularly useful, and suggests that about 15% of files on Wikimedia files may be stored outside of Commons, which is significant (3M out of 23M total).

I would be grateful for any URLs that would make it easy for us to test Media Viewer performance on the largest sites that have that practice of local hosting (e.g. English Wikipedia, who else?).

Laura, your URLs of local files on Wikinews is exactly what I’m looking for on other sites, thanks. A casual check suggests that these files open in Media Viewer, but their metadata doesn’t display, which could be due to Wikinews using a different template than Commons.

So my next question to the group is what you think can be done to encourage communities like Wikinews to consider adapting their templates to match the Commons more closely? Otherwise, their local images will not be as useful in Media Viewer.

This may not be all that big of a change, and we can document this more specifically, but could use some help from community members to figure out practical solutions for updating these local templates.

What do you think?

Thanks again for all your help with this project.


Fabrice

Don't know of any tool which would give these numbers cross-wiki, though.

Shell script on toolserver querying all the dbs would probably be pretty easy.

As for metadata similar to commons - almost certainly not. Especially on smaller non english wikis.

We are trying to assess how many images are stored locally on Wikimedia sites, rather than hosted on Commons. We also want to better understand what templates they are using for their metadata.

Does anyone know where we could find reliable statistics and links for these non-Commons files?

Does not ring a bell to me. :-(

Closer I recall  is the opposite  − projects that do not need to be checked for non-CommonsFiles

Hi guys,

We would like to check how well they work with Media Viewer, as well as get a sense of scope. 

If they use the same templates and data structure as Commons, they should display well in Media Viewer. But if they use different templates, these would need to be modified for their meta-data to appear in Media Viewer.

Last time we checked, there were over 800k image files hosted on English Wikipedia alone, so this could be a significant number, which may require some advance work to get them ready for Media Viewer.

Gergo is preparing a document to address the template issue, which he can share with us when it’s ready.

Thanks,


Fabrice
