Structured Data on Commons can help you analyse information about media files and spot inconsistencies and errors. One example is geographical coordinates.
Many photographs on Commons contain the coordinates of where they were taken in their metadata, as saved by the device (mobile phone or camera). This is very useful information, but it's not always correct. If your camera saves erroneous coordinates with your photo, there's a risk you won't notice it when uploading the photo to Commons.
But now that the coordinates are included in SDC, it also makes them easier to spot. We can use the Wikimedia Commons Query Service to plot photos on a map, and anything suspicious will stand out.
We discovered this when working with structured data in Wiki Loves Monuments photos. First, we add information about the competition to all photos in a country's category, for example Images from Wiki Loves Monuments 2021 in Iran.
We can easily see all the files whose coordinates are clearly not in Iran! We can now remove the coordinates from both the file page's wikitext and the SDC.
Note that the Wikimedia Commons Query Service is still in beta, and doesn't update automatically. The data is updated via weekly dumps. So you won't be able to see your edits reflected in the map until after a couple days.
You can follow our work with SDC and WLM photos here. There you can find a list of the countries we've worked on – some recent updates include Georgia and Venezuela – as well links to the SPARQL map queries.
How many bad coordinates can you spot in your country?
Needs assessment – video recorded interviews
Previous interviews have shown quite similar needs and where more resources are needed. We have now switched over and started recording interviews to be able to go back and follow longer reasoning on certain issues. Examples of questions we've discussed - Do we need more Wikimedia ambassadors to talk about the benefits of the platforms? How could one conduct courses and collaborations with a global perspective? What would a mentorship program for content partnership look like?

ISA is a tool that allows you to add structured data to images on Wikimedia Commons. It was developed in collaboration between Wiki In Africa, Histropedia and the Structured Data on Commons project. While it is still running and being used frequently, it has seen few updates since the initial development project ended.
We will be helping out with some development time to make sure that the tool will continue to be usable. So far we have solved a couple of security issues. We have now started working on some of the more noticeable issues, including slow loading of campaign pages and localisation, with more features planned to come.
