One of the reasons that YourNextMP.com was created was because there was no central list of candidates. So we created one.
But we don't want anyone to duplicate our efforts collecting the candidate information - we'd rather that they were doing something interesting with the data instead. So almost all the data we have is now available under a Creative Commons license as JSON endpoints.
At the bottom of most pages you will now see a little 'json' link. If you click on it you will get the same data that we used to create the page in the JSON format which you can easily read into your code and do things with.
We've chosen the CC by-nc-sa license - which means that you must attribute where you got the data from, you can't use it commercially and you have to apply this same license to the work that you produce. Hopefully this is liberal enough for most people. If it isn't please contact us and we'll see what we can do.
UPDATE: we're now using the 'by-sa' license - we dropped the 'nc'.
Hopefully the data structure we've used is fairly self-explanatory. Documentation will be appearing on the site soon.
Let us know what you create with it!
