Dear @MartinPoulter, thanks for contributing to Commons Impact Metrics! The requested category has been available since the start of April, with data starting on March 1st.

Apologies for the delay in updating you here, but we had a data processing problem involving the retrieval of the imagelinks table from the wiki databases. Some tables in the wiki databases have seen changes recently, and this traditionally causes problems. I want to highlight that this was not a problem with the Commons analytics API (Commons Impact Metrics), but the problem directly affected it. In order to correct the data from March, we needed to wait for the first problem to be fixed, so that we could run March again. All the March requests are included, running, and no data was lost.

If you need more information about CIM, here are some tips:

Commons Impact Metrics can be accessed via this page. It offers metrics for categories, media files, or users. You should add the category as "Cambridge_University_Library", with the underscores. The rest of the information requested is pretty straightforward (date, category-scope, wiki, etc).

If you need it, there is this Diff post and this recording (minute 39:00) from a DPLA Webinar, in July 2024. And here are the slides for the presentation during the GLAM Global call.

Ways to use CIM:

1. This tool shows metrics more visually. However, your category might not be there already.

2. There is a way to offer views from CIM metrics on a Commons category. The Digital Public Library of America developed this:

Template:Views from category
Template:Views from category/table
Example: Category:Images from the Swedish National Heritage Board
Example: Category talk:Images from the Swedish National Heritage Board/Views

3. This dashboard, developed by the Biodiversity Heritage Library, offers some visualization options too.

We will be working on a CIM-related training at some point, but I hope this helps for now. Let me know if you have questions.
