I originally posted this on the Science Museum API wiki in 2008, this version dates from about March 2011 (when I left the Science Museum Group to start a PhD).

At that point, the APIs available related to various exhibitions, collections etc were: APIs: Collections, Pledges, Countries, Object Wiki, Exhibitions.

Science Museum API documentation

These documents describe the functionality of the Science Museum APIs.

The APIs have been released as a trial. As such, they should be considered 'beta', and things may change without warning.

If you are interested in devloping using these APIs, or want to ask any questions or make any suggestsions about them, please email us at web.team@nmsi.ac.uk or leave a comment at http://sciencemuseumdiscovery.com/blogs/museumdev.

In addition to the APIs documented here, we have an XML-based API with objects from the exhibition Cosmos & Culture at http://www.sciencemuseum.org.uk/objectapi/cosmosculturepublic.svc/MuseumObjects.
