Quoting myself over on the museum developers blog, Cosmic Collections – do one thing and do it well:
I’ve realised that there may be some mismatch between the way mashups tend to work, and the scope we’ve suggested for entries to our competition. The types of interfaces someone might produce with the API may lend themselves more to exploring one particular idea in depth than produce something suitable for the broadest range of our audiences.
So I’m proposing to change the scope for entries to the competition, to make it more realistic and a better experience for entrants: I’d like to ask you to build a section of a site, rather than a whole site. The scope for entrants would then be: “create something that does one thing, and does it well”. Our criteria – use of collections data, creativity, accessibility, user experience and ease of deployment and maintenance – are still important but we’ll consider them alongside the type of mashup you submit.
In other news, programmableweb published a blog post about the competition today: Science Museum Opens API and Challenges Developers to Mashup the Cosmos. Woo!
And I don't know if it's any kind of consolation if you're entering, but I'll be working right alongside you up until Friday 28th, on an assignment for my MSc.
