Andrew, I would suggest moving in a Linked Data direction, rather than inventing yet another API with its own set of rules and data formats. One simple first step you could take is to create simple persistent identifiers for each object in your collection. As an example, the National Trust (which uses the same underlying CMS software as you) has identifiers like this on its collection search site: http://www.nationaltrustcollections.org.uk/object/446824 which 'dereference' (as the current jargon has it) to a web page describing the object in question. This makes it easy for people to bookmark objects and quote them, using /National Trust/// URLs rather than URLs of their own invention. A corresponding item URL from your collection would be: http://www.royalcollection.org.uk/collection/search#/1/collection/606546/felipe-iii which contains both search-specific information and gratuitous descriptive text. This is much less useful as a bookmark. Going beyond this, I would suggest implementing Linked Data content negotiation on these URLs, and the delivery of machine-processible versions of your collections data. This would make your collections available in the same way as a custom API would, but using standard web protocols and delivery formats.

I'd really like us to, but its not on the immediate horizon at the moment. Any case studies/arguments for impact of introducing one would be greatly appreciated! -- *Richard Light* I've done the Big London Night (half marathon) Walk 2015 for the Big Issue Foundation: can you please support them? :- http://uk.virginmoneygiving.com/RichardBrianLight **************************************************************** website: http://museumscomputergroup.org.uk/ Twitter: http://www.twitter.com/ukmcg Facebook: http://www.facebook.com/museumscomputergroup [un]subscribe: http://museumscomputergroup.org.uk/email-list/ ****************************************************************
