Using the COPTR data feed
 Accessing the COPTR data
- I'd like to take the data in COPTR and create a funky 3D spinny view that helps people navigate the data and find what they are looking for. Can I do this, and can I host it somewhere else?
- Yes, that would be excellent! The COPTR content is made available under a CC-BY-SA license but we ask that if possible you point your users back to this site if they have corrections or new tools to add.
 Ways to access the COPTR data
We offer two main channels for accessing the data - the MediaWiki API, and XML dumps of the MediaWiki content.
 The COPTR API
As COPTR is based on MediaWiki, you can access the COPTR content via the MediaWiki API. The Official MediaWiki API Documentation is a pretty good starting point, and the endpoint itself is fairly self-documenting. However, to help get you started, here are a couple of examples.
 Machine-Readable Recent Changes
If you want access to information on what has changed recently, just like the RecentChanges page, but in a machine-readable form, you can construct a URL like this:
Breaking down those query parameters, we have:
|action||query||Perform a query action, rather than e.g. adding or editing a page.|
|list||recentchanges||Perform a query on the 'recent changes' list (one of many lists available).|
|format||json||Return the results in JSON format.|
|rclimit||500||Return up to 500 results at once (500 is the maximum per request, but there are other parameters for paging).|
|rctype||new||Return only 'new page' events.|
|rcprop||title|ids|sizes|flags|user|timestamp||For each event, return these fields (see the API docs for more detail).|
So, for example, if you would rather receive XML, you can just modify the format parameter.
 Category Members
There is also a Category Members list you can query. For example:
- This query lists all the subcategories belonging to the Function category.
- This query lists the Page IDs and Title of all the pages belonging to the Fixity category.
 The COPTR Database Backup Dumps
We also make daily XML dumps available, for backup and re-use purposes. You can find them in the backup-dumps folder,
